Transaction value method — statutory additions to price paid or payable
Once the price paid or payable for goods sold for export to Canada can be determined and the acceptability conditions in subsection 48(1) of the Customs Act are met, the value for duty is calculated by adjusting that price in accordance with subsection 48(5). Paragraph 48(5)(a) prescribes six categories of additions that must be made to the price paid or payable to the extent that each such amount is not already included in that price. These adjustments are the operational core of Canadian customs valuation practice for multinational importers.
Commissions and brokerage (subparagraph 48(5)(a)(i))
Commissions and brokerage incurred in respect of the goods by the purchaser must be added to the price paid or payable. The exception is buying-agent fees: if the purchaser engages a person to locate and purchase goods for export to Canada on the purchaser's behalf, the buying agent's fee is not dutiable and may be excluded when determining the transaction value. The term "brokerage" does not refer to charges by a customs broker for services rendered in respect of clearance of the imported goods; those fees are not added to the value for duty. If customs brokerage fees are included in the price paid or payable, they may be deducted under paragraph 48(5)(b) as associated costs.
Packing costs and charges (subparagraph 48(5)(a)(ii))
Packing costs and charges incurred by the purchaser in respect of the goods must be added, including the cost of cartons, cases, and other containers and coverings that are treated for customs purposes as being part of the imported goods, and all expenses of packing incident to placing the goods in the condition in which they are shipped to Canada. Both labour and material costs are to be considered in determining the expenses of packing incident to placing the goods in the condition in which they are shipped to Canada.
Assists (subparagraph 48(5)(a)(iii))
The value of any goods and services supplied, directly or indirectly, by the purchaser free of charge or at a reduced cost for use in connection with the production and sale for export of the imported goods must be added, apportioned to the imported goods in a reasonable manner and in accordance with generally accepted accounting principles. The term "assist" does not appear in the Customs Act but is convenient shorthand for the four categories enumerated in clauses (A) through (D): (A) materials, components, parts, and other goods incorporated in the imported goods; (B) tools, dies, moulds, and other goods utilized in the production of the imported goods; (C) any materials consumed in the production of the imported goods; and (D) engineering, development work, art work, design work, plans, and sketches undertaken elsewhere than in Canada and necessary for the production of the imported goods. The parenthetical "undertaken elsewhere than in Canada" means that the value of such engineering and design work undertaken in Canada is not to be added to the price paid or payable under the transaction value method, even when supplied by the purchaser free of charge or at a reduced cost.
Section 4 of the Valuation for Duty Regulations prescribes the manner of determining the value of assists. For materials, components, and parts incorporated in the goods (clause (A)), and materials consumed in production (clause (C)), the apportionment is usually based on the number of components or the quantity of material incorporated in or consumed in the production of the imported goods. For tools, dies, and moulds utilized in production (clause (B)), the value is apportioned over the number of units produced with the assist. The importer should be prepared to furnish documentation to the CBSA establishing the appropriateness of the apportionment method and a record of the imported units to which the value of the assist has been apportioned.
Royalties and licence fees (subparagraph 48(5)(a)(iv))
Any royalty or licence fee in respect of the imported goods that the purchaser is required to pay, directly or indirectly, as a condition of the sale of the goods for export to Canada must be added to the price paid or payable. Two requirements must both be met: the payment must be in respect of the imported goods, and it must be a condition of the sale of those goods for export to Canada. Payments for the right to reproduce the imported goods in Canada are not to be added to the price paid or payable, because such a payment is not in respect of the imported goods themselves but for the right to use them to produce further goods in Canada. CBSA Memorandum D13-4-9 provides that the Supreme Court of Canada's decision in Mattel Canada Inc. v. Canada (Commissioner of Customs and Revenue) (2001 SCC 36) establishes that if a royalty or licence fee payment is required to be made, the importer must be aware that in the event of failure to make the payment, the source of supply of the imported goods may be stopped; absent that nexus, the payment is not a condition of sale. The Canadian International Trade Tribunal and the Federal Court of Appeal decisions in Polygram Inc. and Reebok further guide the interpretation of "in respect of the goods."
Subsequent proceeds (subparagraph 48(5)(a)(v))
The value of any part of the proceeds of any subsequent resale, disposal, or use of the goods by the purchaser that accrues or is to accrue, directly or indirectly, to the vendor must be added to the price paid or payable. The term "subsequent proceeds" is a practical shorthand for the statutory phrase. This category captures post-importation payments that flow to the vendor and are connected to the resale, disposal, or use of the imported goods. Dividends are not subsequent proceeds and therefore are not included in the value for duty; the WTO Customs Valuation Agreement recognizes that the price actually paid or payable refers to the price for the imported goods, not a distribution of corporate profits. Payments for research and development made by a related-party purchaser to the vendor after importation are generally considered to be an addition to the price paid or payable and must be included in the value for duty, particularly when the R&D charges relate to development of the imported goods; if the importer can substantiate that a portion of the payment pertains exclusively to research unrelated to existing goods, only the development portion is to be added.
Transportation and associated costs (subparagraph 48(5)(a)(vi))
Costs, charges, and expenses incurred in respect of the international shipment of the goods to Canada must be added, but only to the extent that they arise prior to and at the place from which the goods begin their direct and uninterrupted journey to Canada (the "place of direct shipment"). These include freight, insurance, handling charges, and similar costs up to the place of direct shipment. Any of the costs referred to in subparagraph 48(5)(a)(vi) that arise after the place from which the goods begin their direct and uninterrupted journey to Canada are not included in the transaction value and may be deducted under paragraph 48(5)(b) if they are included in the price paid or payable. CBSA Memoranda D13-3-3 and D13-3-4 provide detailed guidance on the treatment of transportation and associated costs and the determination of the place of direct shipment.
Statutory floor and consequences of insufficient information
Subsection 48(6) of the Customs Act provides that where there is not sufficient information to determine any of the amounts required to be added to the price paid or payable in respect of any goods being appraised, the value for duty of the goods shall not be appraised under section 48. In such instances, the goods must be appraised under an alternative method in accordance with sections 49 to 53, applied in sequential order. This is a hard gate: if an importer knows that an assist, a royalty, or a subsequent-proceeds payment exists but cannot quantify it, the transaction value method is unavailable, and the importer must proceed to the transaction value of identical goods (section 49), then similar goods (section 50), then the deductive value method (section 51), then the computed value method (section 52), and finally the residual method (section 53).

Transaction value method — deductions from price paid or payable
Under paragraph 48(5)(b) of the Customs Act, certain costs that are included in the price paid or payable must be deducted when determining the transaction value for duty. These deductions are the mirror image of the statutory additions prescribed in paragraph 48(5)(a), and they are essential for calculating the correct customs value when the invoice price includes costs that arose after the place from which the goods began their direct and uninterrupted journey to Canada (the "place of direct shipment"). Importers shipping under delivered-duty-paid (DDP), delivered-duty-unpaid (DDU), or cost-insurance-freight (CIF) pricing structures routinely rely on these deductions to avoid paying duty on non-dutiable elements bundled into the invoice price.
Transportation and associated costs from the place of direct shipment (subparagraph 48(5)(b)(i))
Any of the costs, charges, and expenses incurred in respect of the international shipment of the goods that arise after the place from which the goods begin their direct and uninterrupted journey to Canada may be deducted from the price paid or payable, to the extent that they are included in that price. The place of direct shipment is the physical location where the goods are loaded onto the carrier with a specific destination in Canada identified on the transportation documents and where the event that caused the goods to be shipped to Canada has occurred. CBSA Memorandum D13-3-4 provides that the event, time, and place must coincide: the event (e.g., the sale for export to Canada or the order to ship), the time (when the goods are identified as destined for Canada), and the place (the loading point) together establish the place of direct shipment.
Transportation and associated costs that arise prior to and at the place of direct shipment are dutiable and must be added to the price paid or payable under subparagraph 48(5)(a)(vi). Only costs that arise after the place of direct shipment are excludable under subparagraph 48(5)(b)(i). These costs include freight charges for movement of the goods by truck, aircraft, train, or ship; handling charges for loading and unloading; marine or air insurance from the place of direct shipment to Canada; and similar associated costs. The deduction is available only to the extent that the actual amount of the cost is known or can be determined and is separately identified; estimated or notional amounts may not be deducted.
Canadian customs brokerage fees
Canadian customs brokerage fees—that is, fees paid to a customs broker for services rendered in respect of the clearance of the imported goods—may be deducted as associated costs under subparagraph 48(5)(b)(i) if they are included in the price paid or payable. The term "brokerage" in the statutory additions provision (subparagraph 48(5)(a)(i), referring to commissions and brokerage incurred by the purchaser in respect of the goods) does not refer to customs brokerage fees; those fees are not dutiable and may be subtracted if they are included in the invoice. CBSA Memorandum D13-4-7 and Memorandum D13-3-3 confirm this treatment.
Post-importation services (subparagraph 48(5)(b)(ii))
Any reasonable cost, charge, or expense that is incurred for construction, erection, assembly, maintenance, or technical assistance undertaken in Canada after the importation of the goods may be deducted from the price paid or payable, to the extent that the cost is identified separately from the price paid or payable for the goods. The key requirement is separate identification: if a lump-sum invoice includes the price of machinery and the cost of on-site installation or commissioning in Canada, and those installation costs are separately itemized, they may be deducted under subparagraph 48(5)(b)(ii). If they are not separately identified—for example, if the vendor quotes a single turnkey price—the deduction is unavailable, and the entire turnkey price forms part of the value for duty.
The term "technical assistance" in this context generally refers to post-importation services such as training of the purchaser's personnel in the operation or maintenance of the imported goods, or on-site assistance with commissioning or calibration. The assistance must be provided after importation; pre-importation technical services (such as engineering or design work undertaken outside Canada and necessary for the production of the imported goods) are dutiable under clause 48(5)(a)(iii)(D) as assists and are added to the price paid or payable, not deducted.
Duties and taxes paid in Canada (subparagraph 48(5)(b)(iii))
Duties and taxes levied under the Customs Tariff, the Excise Tax Act, the Excise Act, 2001, the Special Import Measures Act, or any other law relating to customs may be deducted from the price paid or payable if they form part of that price and are identified separately. For example, if a foreign vendor invoices a Canadian purchaser a lump sum that includes the purchase price of the goods plus the amount of Canadian customs duties and goods and services tax (GST) that the vendor has calculated or estimated, and if those duties and taxes are identified separately on the invoice or expressed as a percentage of the price, they may be deducted under subparagraph 48(5)(b)(iii). The amount to be deducted must be the actual amount of Canadian duties and taxes levied; an estimated or notional amount may not be deducted.
In practice, this deduction is invoked when a vendor quotes a delivered-duty-paid price that includes Canadian duties and GST as part of the purchase price. The vendor may include these amounts to simplify the transaction for the purchaser or to absorb the border cost. To claim the deduction, the importer must demonstrate that the duties and taxes have been separately identified, and the amount must correspond to the actual duties and taxes payable on the importation. CBSA Memorandum D13-4-7 confirms that the amount must be identified separately on the invoice or expressed as a percentage.
No deduction for post-importation price reductions (paragraph 48(5)(c))
Paragraph 48(5)(c) of the Customs Act provides that any rebate of, or other decrease in, the price paid or payable for the imported goods that is effected after importation must be disregarded when determining the transaction value. This prohibition is a hard gate: if a purchaser and a vendor enter into an agreement to reduce the price paid or payable after the goods have been imported to Canada—for example, to improve the purchaser's price competitiveness in the Canadian market, or because of defects discovered after importation—the value for duty cannot be amended to reflect that post-importation price reduction.
The CBSA allows a narrow exception for price reductions that result from an agreement that is in writing and is in effect at the time the goods are imported. For instance, a deferred discount (a retroactive discount given by the vendor when the purchaser satisfies certain obligations, such as reaching a specified volume of purchases over a year) is considered to be in effect at the time of importation if it ensues from a written agreement that existed when the goods were imported. Similarly, a cash discount or prompt-payment discount that is negotiated before importation and is still available (though not yet taken) at the time the goods are accounted for may be applied to reduce the value for duty if the purchaser subsequently takes advantage of the discount. CBSA Memorandum D13-4-10 provides detailed guidance on the treatment of price reductions, including deferred discounts and volume rebates.
The prohibition in paragraph 48(5)(c) does not extend to corrections of clerical errors or to transfer-pricing adjustments between related parties that are made under a documented transfer-pricing policy that was in effect at the time of importation. CBSA Memorandum D13-4-5 notes that, for related-party transactions, transfer-pricing adjustments may be recognized if the adjustment is pursuant to a pre-existing, documented methodology and the importer maintains records demonstrating that the final transfer price was determined in accordance with that methodology.
Documentary requirements and burden of proof
To claim any deduction under paragraph 48(5)(b), the importer must maintain documentation that substantiates the amount and the nature of the cost being deducted. For transportation-cost deductions, this typically includes freight invoices, bills of lading showing the place of direct shipment, and carrier contracts. For post-importation service deductions, invoices or contracts separately itemizing construction, installation, or technical-assistance charges are necessary. For duty-and-tax deductions, the vendor's invoice must separately state the amounts or express them as a percentage. Paragraph 152(3)(d) of the Customs Act places the burden of proof on the importer in any question relating to compliance with the Act, not on the Crown. If the CBSA requests documentation supporting a deduction and the importer cannot provide it, or if the amount cannot be separately identified, the deduction will be disallowed and the entire invoice price will be included in the value for duty.
Consequence of insufficient information
If an importer knows that a deductible cost exists but cannot quantify it or cannot identify it separately, the deduction is unavailable, but the transaction value method is not automatically disqualified on that ground alone (in contrast to the rule for additions under subsection 48(6), which provides that insufficient information to determine a required addition precludes the use of section 48). The inability to substantiate a deduction means only that the deduction is not made, and the value for duty includes the full price paid or payable as invoiced. However, if the price paid or payable itself cannot be determined—because the invoice includes non-dutiable elements that are not separately identified and the importer has no other reliable basis to apportion them—the transaction value method may be unavailable, and the importer must proceed to the transaction value of identical goods (section 49), similar goods (section 50), deductive value (section 51), computed value (section 52), or the residual method (section 53).

Deductive value method (section 51) — price per unit and deductions
When the transaction value method (section 48) and the transaction value of identical or similar goods (sections 49–50) cannot be applied, the deductive value method under section 51 of the Customs Act is the next sequential method, unless the importer has requested under subsection 47(3) that the order of sections 51 and 52 be reversed. Section 51 determines the value for duty by looking to sales in Canada of the imported goods, or of identical or similar imported goods, and working backward: the importer establishes a resale price per unit in the Canadian market, then deducts profit, general expenses, transportation costs, Canadian duties and taxes, and (where applicable) the value added by further processing in Canada. This method is the most commonly invoked fallback for multinational enterprises when related-party transaction values fail the section 48(1)(d) test and the importer lacks access to cost-of-production data for the computed value method (section 52).
Statutory structure and applicability
Subsection 51(1) of the Customs Act provides that, subject to subsections (5) and 47(3), where the value for duty of goods is not appraised under sections 48 to 50, the value for duty of the goods is the deductive value of the goods. Subsection 51(2) defines "deductive value" as the price per unit at which the greatest number of units of the goods being appraised, or of identical or similar goods, is sold in Canada at the earliest of three time points after importation, minus the deductions specified in subsection 51(4). The three time points prescribed in paragraphs 51(2)(a), (b), and (c) are: (a) at or about the time the goods being appraised are imported, in the condition as imported; (b) at or about the time the goods being appraised are imported, after further processing; or (c) not later than 90 days after the goods being appraised are imported, in the condition as imported. The importer may choose which of these three time points to use, provided that there are sufficient sales data at that point. CBSA Memorandum D13-7-1 notes that the deductive value method expects that value for duty will be based upon a price per unit derived from a sale of goods after importation—that is, a sale in the Canadian market—and not from the sale that prompted the international transfer of the goods.
The deductive value method can only be applied when there are sales in Canada of the imported goods, or of identical or similar goods, in sufficient quantity to permit a determination of the price per unit. If the goods are not resold in Canada—for example, if the importer consumes the goods in its own manufacturing process—or if there is only a single sale or an insufficient number of sales, the deductive value method is unavailable, and the importer must proceed to the computed value method (section 52) or the residual method (section 53). CBSA Memorandum D13-10-2, which addresses valuation of used automobiles and vessels, confirms that the deductive value method "can only be used when the goods being appraised are to be resold."
Determination of the price per unit
The price per unit is the price at which the greatest number of units of the goods is sold in Canada. Subsection 51(3) specifies that there must be a sufficient number of sales to permit a determination of the price per unit, and that such sales must be made at the first commercial level after importation at which the greatest number of units is sold to persons who are not related to the seller. CBSA Memorandum D13-7-1 provides that the number of sales that constitutes a "sufficient number" will depend on the circumstances and the marketing practices surrounding the importation and the sales in Canada. For example, if only a small percentage of the imported goods are sold within the time limits established in subsection 51(2), these sales may be acceptable for the purposes of establishing a price per unit if the price at which they are sold is consistent with the usual selling price of the goods, as indicated by a bona fide price list supported by commercial invoices or, where a price list is not used, by examining the recent trading history of the importer.
If goods are sold at various prices—for example, because the importer sells to distributors, wholesalers, and retailers at different volume-discount tiers—the price per unit is the price at which the greatest aggregate number of units is sold. CBSA Memorandum D13-7-1 illustrates this with an example: if an importer sells 6,000 units to distributors at $0.95, 5,700 units to distributors at $0.98, and 1,000 units to distributors at $1.00, and also sells 7,000 units to wholesalers at $1.00, the price per unit is $1.00, because the greatest number of units (8,000 in total: 1,000 to distributors plus 7,000 to wholesalers) is sold at that price. However, the Memorandum cautions that the price per unit at which the greatest number of goods is sold would not be acceptable if the number of goods sold at that price is only a small percentage of the total sales of those goods.
The amount, if any, of the goods and services tax (GST) or other domestic retail sales tax added to, or included in, the selling price of the goods must be excluded in determining the price per unit. Sales to related persons are excluded from the determination of the price per unit; only sales to unrelated purchasers may be used.
Deductions from the price per unit (subsection 51(4))
Subsection 51(4) of the Customs Act prescribes five categories of deductions that must be made from the price per unit to arrive at the deductive value. These deductions, elaborated in section 5 of the Valuation for Duty Regulations and CBSA Memorandum D13-7-3, are:
(a) Commissions or profit and general expenses (paragraph 51(4)(a)) An amount equal to either (i) the amount of commission generally earned on a unit basis, or (ii) the amount for profit and general expenses, including all costs of marketing the goods, considered together as a whole, that is generally reflected on a unit basis in connection with sales in Canada of goods of the same class or kind as those goods. These are alternative deductions: the importer may deduct either commissions or profit-and-general-expenses, not both. The profit and general expenses to be deducted must be limited to those incurred in Canada to be considered "in connection with sales in Canada," and the amount to be deducted is that which is generally earned or reflected on a unit basis of sales in Canada of imported goods of the same class or kind. Section 5 of the Valuation for Duty Regulations provides that if the CBSA determines that figures for profit and general expenses supplied by or on behalf of the importer are unacceptable, the CBSA will apply an amount based on relevant and quantifiable data from sales in Canada of imported goods of the same class or kind, or of the narrowest group or range of goods that includes the goods being appraised. The amount for profit and general expenses is to be calculated as a whole and expressed as a percentage of selling price.
(b) Transportation and insurance costs within Canada (paragraph 51(4)(b)) An amount equal to the costs, charges, and expenses generally incurred in respect of the transportation and insurance of the goods within Canada and the costs, charges, and expenses associated therewith that are generally incurred in connection with sales in Canada of the goods being appraised, identical goods, or similar goods, to the extent that an amount for such costs, charges, and expenses is not deducted in respect of general expenses under paragraph 51(4)(a). This deduction covers costs incurred for warehousing, distribution, and delivery within Canada. It can only be made if such an amount has not already been deducted in respect of general expenses; there is no double-counting.
(c) Transportation and insurance from place of direct shipment (paragraph 51(4)(c)) An amount equal to the costs, charges, and expenses in respect of the transportation and insurance of the goods from the place of direct shipment of the goods to Canada, to the extent that an amount for such costs, charges, and expenses is not deducted in respect of general expenses under paragraph 51(4)(a). The "place of direct shipment" is the location where the goods begin their direct and uninterrupted journey to Canada, as defined in CBSA Memorandum D13-3-4. This deduction parallels the deduction available under paragraph 48(5)(b)(i) for the transaction value method. Again, it can only be made if such an amount has not already been deducted in respect of general expenses.
(d) Canadian duties and taxes (paragraph 51(4)(d)) An amount equal to the duties and taxes levied under the Customs Tariff, the Excise Tax Act, the Excise Act, 2001, the Special Import Measures Act, or any other law relating to customs, paid or payable in respect of the goods, to the extent that an amount for such duties and taxes is not deducted in respect of general expenses under paragraph 51(4)(a). This deduction removes from the Canadian resale price the duties and taxes that were imposed at importation. The deduction is for the actual amount paid or payable; estimated amounts may not be deducted.
(e) Value added by further processing in Canada (paragraph 51(4)(e)) If the goods being appraised are assembled, packaged, or further processed in Canada after importation and if sales of these goods are used to determine the price per unit, the value added by assembly, packaging, or further processing must be deducted from the price per unit. The amount to be deducted for the value added by such work will be based on sufficient information relating to the cost of such work. CBSA Memorandum D13-7-3 notes that paragraph 51(4)(e) would normally not be applicable when, as a result of further processing, the imported goods lose their identity. However, there can be instances where, although the identity of the imported goods is lost, the value added by the processing can be determined accurately without unreasonable difficulty. On the other hand, there can also be instances where the imported goods maintain their identity but form such a minor element in the goods sold in Canada that the use of this valuation method would be unjustified. In view of the above, an importer must be prepared to support the applicability of the deductive value method where further processing in Canada occurs. Reference can be made to industry formulas, recipes, methods of construction, and other industry practices in determining the amount to be deducted.
Documentary and evidentiary requirements
The importer bears the burden of proof under paragraph 152(3)(d) of the Customs Act for any question relating to compliance with the Act. To substantiate a deductive value determination, the importer must provide the CBSA with documentation establishing the resale prices in Canada (invoices to unrelated purchasers, price lists), the volume of sales at each price point, and the amounts claimed as deductions for profit, general expenses, transportation, duties, and processing costs. Industry data or accounting records demonstrating that the profit-and-general-expenses percentage is consistent with that generally reflected in sales in Canada of goods of the same class or kind are typically required. If the importer cannot provide sufficient information to determine the price per unit or to substantiate the deductions, the deductive value method cannot be applied, and the importer must proceed to the computed value method (section 52) or the residual method (section 53).

Computed value method (section 52) — cost build-up from producer data
When the transaction value method (section 48), the transaction value of identical or similar goods (sections 49–50), and the deductive value method (section 51) cannot be applied, the computed value method under section 52 of the Customs Act is the next sequential method, unless the importer has requested under subsection 47(3) that the order of sections 51 and 52 be reversed. Section 52 determines the value for duty by building up from the producer's cost of production: the importer obtains the producer's commercial accounts showing the cost of materials, the cost of production or other processing, and certain other elements, then adds an amount for the profit and general expenses that producers in the country of export generally reflect in sales to Canada. This method is rarely invoked in practice, because it requires detailed cost-of-production data from the foreign producer—information that is typically unavailable unless the importer is related to the producer, which is precisely the circumstance that often triggers rejection of the transaction value method in the first instance.
Statutory structure and applicability
Subsection 52(1) of the Customs Act provides that, subject to subsection 47(3), where the value for duty of goods is not appraised under sections 48 to 51, the value for duty of the goods is the computed value of the goods if it can be determined. The computed value is defined in subsection 45(1) as "the value of the goods determined in accordance with section 52."
The computed value method can only be applied when the importer can obtain sufficient information relating to the production of the goods from the producer in the country of export. CBSA Memorandum D13-3-1 notes that, in order to determine a value for duty under the computed value method, it will be necessary to obtain information from the country of production of the goods, normally from the producer. Because production cost data is commercially sensitive and confidential, foreign producers who are not related to the Canadian importer rarely disclose such information. Consequently, the computed value method is generally only used by an importer who is related to the producer or who otherwise has access to the producer's commercial accounts. CBSA Memorandum D13-8-1 confirms that the amounts required to be included in the computed value must be determined on the basis of the commercial accounts of the producer or other sufficient information relating to the production of the goods being appraised, supplied by or on behalf of the producer and prepared in a manner consistent with the generally accepted accounting principles of the country of production.
Elements of the computed value (subsection 52(2))
Subsection 52(2) of the Customs Act provides that the computed value of goods being appraised is the aggregate of amounts equal to the sum of two principal components set out in paragraphs 52(2)(a) and (b). Paragraph 52(2)(a) requires the inclusion of the costs, charges, and expenses incurred in respect of, or the value of, (i) materials employed in producing the goods being appraised, and (ii) the production or other processing of the goods being appraised. Paragraph 52(2)(b) requires the inclusion of an amount for profit and general expenses equal to that generally reflected in sales of goods of the same class or kind as the goods being appraised that are made by producers in the country of export of the goods being appraised for export to Canada. These two components—cost of production (paragraph (a)) plus profit and general expenses (paragraph (b))—constitute the core of the computed value.
Inclusions deemed to be part of materials and production costs (subsection 52(3))
Subsection 52(3) of the Customs Act specifies that, for purposes of subsection 52(2), the costs, charges, and expenses or value referred to in paragraph 52(2)(a) are deemed to include three categories of costs:
(a) Packing costs (paragraph 52(3)(a)) The packing costs and charges referred to in subparagraph 48(5)(a)(ii) of the Customs Act—that is, the cost of cartons, cases, and other containers and coverings that are treated for customs purposes as being part of the imported goods, and all expenses of packing incident to placing the goods in the condition in which they are shipped to Canada. Both labour and material costs of packing are included. CBSA Memorandum D13-8-1 confirms that these packing costs are considered to be included in the elements of paragraph 52(2)(a) and are therefore part of the computed value.
(b) Assists (paragraph 52(3)(b)) The value of any goods and services referred to in subparagraph 48(5)(a)(iii) of the Customs Act—that is, assists supplied directly or indirectly by the purchaser free of charge or at a reduced cost for use in connection with the production and sale for export of the imported goods, apportioned in accordance with that subparagraph. The four categories of assists enumerated in clauses 48(5)(a)(iii)(A) through (D) are: materials, components, parts, and other goods incorporated in the imported goods; tools, dies, moulds, and other goods utilized in the production of the imported goods; materials consumed in the production of the imported goods; and engineering, development work, art work, design work, plans, and sketches undertaken elsewhere than in Canada and necessary for the production of the imported goods.
CBSA Memorandum D13-8-1 provides detailed guidance on the treatment of assists when calculating the computed value. The value of an assist provided free of charge should not be included as part of the elements in subparagraphs 52(2)(a)(i) and (ii) for purposes of calculating an amount for profit and general expenses over costs as specified in paragraph 52(2)(b), but should be added as part of the elements of subparagraphs 52(2)(a)(i) and (ii) only after the profit-and-general-expenses calculation has been made. This treatment prevents the distortion that would result from calculating a profit-and-general-expenses percentage over a denominator that includes cost elements that the producer did not actually incur. The value of an assist provided at a reduced cost is treated similarly: the portion of the value provided at no cost to the producer is added only after the profit calculation, while the portion of the value for which the producer incurs a cost or charge is included in the base costs when calculating the profit-and-general-expenses percentage.
(c) Engineering work undertaken in Canada (paragraph 52(3)(c)) Any costs, charges, or expenses actually incurred by the producer for engineering, development work, art work, design work, plans, or sketches undertaken in Canada and supplied for use in the production of the goods being appraised. This is the mirror image of the treatment of such work under subparagraph 48(5)(a)(iii), which adds the value of engineering work undertaken elsewhere than in Canada to the transaction value. Engineering work undertaken in Canada is not added to the transaction value under section 48, but if it is supplied to the producer for use in production and the producer incurs a cost for it, that cost is included in the computed value under paragraph 52(3)(c). CBSA Memorandum D13-3-7 confirms that only the costs, charges, or expenses actually incurred by the producer for engineering work undertaken in Canada are to be included in the computed value.
Profit and general expenses (paragraph 52(2)(b))
The amount for profit and general expenses to be added under paragraph 52(2)(b) is "that generally reflected in sales of goods of the same class or kind as the goods being appraised that are made by producers in the country of export of the goods being appraised for export to Canada." This amount must be based on sales for export to Canada by producers in the country of export, not on sales in the domestic market of the country of export or on sales for export to third countries. CBSA Memorandum D13-3-1 notes that the amount for profit and general expenses to be considered when calculating the computed value is the amount generally reflected in export sales to Canada by producers in the country of export, and that the CBSA is prepared to accept the producer's own figures based on sales to Canada of the narrowest range of goods for which accounting records are available.
Subsection 6(1) of the Valuation for Duty Regulations, SOR/86-792, provides that the amount for profit and general expenses referred to in paragraph 52(2)(b) of the Customs Act must be determined on the basis of sufficient information relating to the profit and general expenses of producers in the country of export who produce and sell for export to Canada goods of the same class or kind as the goods being appraised, or, if no such information is available with respect to such sales, on the basis of the profit and general expenses of producers in the country of export who produce and sell for export to Canada the narrowest group or range of goods, that includes goods of the same class or kind as the goods being appraised, for which the necessary information can be provided. The CBSA will accept the producer's own profit-and-general-expenses figures if they are based on the producer's own sales to Canada of the narrowest range of goods for which accounting records are available and are prepared in a manner consistent with the generally accepted accounting principles of the country of production.
If the producer can provide sufficient information relating only to the profit and general expenses generally reflected in that producer's own sales for export to Canada of goods of the same class or kind, the CBSA will accept that information. If the producer cannot provide such information, the CBSA may rely on industry data or other relevant and quantifiable data from sales by producers in the country of export of imported goods of the same class or kind. The profit-and-general-expenses amount is calculated as a percentage of the cost of production and is applied to the aggregate of the cost elements in paragraph 52(2)(a).
Documentary and evidentiary requirements
The importer bears the burden of proof under paragraph 152(3)(d) of the Customs Act for any question relating to compliance with the Act. To substantiate a computed value determination, the importer must provide the CBSA with the producer's commercial accounts or other sufficient information demonstrating the cost of materials employed in producing the goods, the cost of production or other processing, packing costs, the value of assists, and the cost of any engineering work undertaken in Canada. The importer must also provide documentation establishing the amount for profit and general expenses generally reflected in sales to Canada by producers in the country of export of goods of the same class or kind. This information must be prepared in a manner consistent with the generally accepted accounting principles of the country of production. CBSA Memorandum D13-3-8 provides guidance on the application of generally accepted accounting principles in the customs valuation context.
If the importer cannot provide sufficient information to determine the computed value—for example, because the producer refuses to disclose cost-of-production data, or because the profit-and-general-expenses percentage cannot be established from the producer's own sales to Canada or from industry data—the computed value method cannot be applied, and the importer must proceed to the residual method (section 53). In practice, the inability to obtain producer cost data is the most common reason the computed value method is unavailable. CBSA Memorandum D13-3-11 notes that, for goods imported to be used in the assembly, construction, or fabrication of a facility or a machine sold on an installed contract basis, if the goods cannot be valued under sections 48 to 51, the most appropriate valuation approach will likely be section 52, provided the contractor/importer can obtain the necessary cost information from the producer.
Comparison with the deductive value method and request for reversal of order
Under subsection 47(3) of the Customs Act, the importer may request in writing, prior to the commencement of the appraisal of the goods, that the order of application of the deductive value method (section 51) and the computed value method (section 52) be reversed. In other words, the importer may ask the CBSA to consider the computed value method before the deductive value method. This request is advantageous when the importer has ready access to the producer's cost data—for example, because the importer and the producer are related—but does not have sufficient Canadian resale data to apply the deductive value method, or when the goods will be consumed by the importer in its own manufacturing process rather than resold in Canada. CBSA Memorandum D13-8-1 confirms that the importer may reverse the order of application of the deductive value method and the computed value method under the provisions of subsection 47(3).
The request to reverse the order must be made in writing to the CBSA prior to accounting for the goods. If the request is granted and the computed value method is considered first but is found to be inapplicable, the importer must then proceed to the deductive value method (section 51). If both methods are inapplicable, the importer must proceed to the residual method (section 53).

Residual method (section 53) — flexible approach when all other methods fail
When all other customs valuation methods under the Canadian regime—transaction value (section 48), transaction value of identical goods (section 49), similar goods (section 50), deductive value (section 51), and computed value (section 52)—cannot be applied, the Customs Act provides for a final resort: the residual method under section 53. This method is designed as a catch-all, permitting customs authorities and the importer a more flexible approach to determining value for duty in cases where rigid adherence to other methods would be unworkable, but still requiring adherence to WTO Valuation Agreement principles.
Statutory basis and strict limits
Section 53(1) of the Customs Act provides that value for duty shall be determined using "reasonably available means consistent with the principles and general provisions" of the Act and the WTO Customs Valuation Agreement. Importers cannot use methods explicitly prohibited under subsection 53(2) or Article 7.2 of the Agreement. These prohibited methods include: (a) the selling price in Canada of goods produced there; (b) a system providing for the acceptance, for customs purposes, of the higher of two alternative values; (c) the price of goods on the domestic market of the country of exportation; (d) a cost of production other than computed value as defined in section 52; (e) the price of goods for export to a third country; or (f) minimum customs values or arbitrary or fictitious values. Section 53 can only be invoked after genuinely exhausting the prescribed sequence in sections 48 to 52—CBSA will not accept a residual approach unless each prior method has been definitively ruled out.
CBSA guidance and expectations
The CBSA (Canada Border Services Agency) clarifies in Memorandum D13-9-1 that while section 53 allows flexibility, any value derived must approximate as closely as possible a value that would arise under the first five methods. Typical Section 53 situations include: inability to obtain producer cost data (computed value unavailable); insufficient resale transactions to unrelated parties in Canada (deductive value fails); no appropriate identical or similar goods (sections 49 and 50 fail); or transaction value is blocked, usually due to related-party pricing or unquantified additions.
The CBSA may apply any reasonably available, documented approach that draws on objective and verifiable data—such as a blend of partial transaction values, industry benchmarks, or limited cost data—so long as it does not default to any of the explicitly banned methods above. All calculations must be transparent, with objective documentation in the customs file. The result should respect the hierarchy and principles of the WTO Valuation Agreement, including using the most similar available data and avoiding “arbitrary or fictitious values.”
Documentation and practical tips
Importers must retain detailed records demonstrating (1) exhaustion of prior statutory methods, and (2) the logic and support for the proposed calculation. The onus is always on the importer to show that all earlier approaches were truly unavailable, and to support the chosen approach with verifiable, non-arbitrary data. CBSA may audit and challenge any residual basis valuation, and the file should be prepared as if for review.

Who qualifies as a 'purchaser in Canada' for the transaction value method?
Eligibility to use the transaction value method—the primary route for customs valuation in Canada—turns on whether the importer can establish that goods are “sold for export to Canada to a purchaser in Canada.” This determination is a gating issue in both standard and non-resident importer (NRI) scenarios. Failure to meet the statutory requirements means the importer must shift to one of the fallback valuation methods, which are often less favorable and always more complex.
Statutory and regulatory test Under section 48(1)(a) of the Customs Act, transaction value requires a sale for export to Canada "to a purchaser in Canada." The definition is elaborated in section 2.1 of the Valuation for Duty Regulations (SOR/86-792):
A "purchaser in Canada" is:
- a resident, as defined in the Regulations;
- a corporation carrying on business in Canada, with management and control within Canada;
- a non-resident, but only if the non-resident imports for their own consumption, use, or enjoyment—not for immediate sale—or for sale in Canada when they have not entered a sale agreement with a resident before importing;
- a permanent establishment in Canada.
For non-resident importers, the decisive factor is whether the non-resident is importing on its own account or as agent on behalf of a Canadian resident who is already a buyer under a binding contract before import. When a non-resident has no pre-existing sale to a Canadian resident, and imports into its own inventory for subsequent Canadian sale, it may qualify as a “purchaser in Canada.” But if a contract with a Canadian customer exists before the goods’ arrival, the Canadian customer is seen as the purchaser.
CBSA’s Customs Valuation Handbook (“Purchaser in Canada”, Ch. 2) provides practical examples illustrating these points. For instance, an NRI who imports goods to warehouse in Canada—intending to sell later to unidentified customers—may qualify, but an NRI who acts as conduit under a prior sales agreement (e.g., direct drop shipment) does not. The actual business arrangements, timing of contract formation, and flow of title and risk all factor into the CBSA’s determination. The Handbook does not employ the “substance over form” phrase, but stresses factual detail over mere invoice addresses or declared parties.
Typical audit flags CBSA audit scrutiny focuses on scenarios such as:
- Multi-tiered sales chains involving both foreign and domestic entities;
- NRI importers with contracts to sell to Canadian customers before importation;
- Arrangements that appear to disguise an agency or pre-sale structure to claim transaction value eligibility.
Ultimately, the onus is on the importer to maintain clear records supporting its status, with documentary evidence: contracts, transport records, and proof of when (and to whom) title and risk passed. If the CBSA determines the importer does not meet the criteria, the fallback valuation hierarchy applies.

CBSA policy on transfer pricing adjustments and customs value: Post-import corrections for related-party transactions
A recurring and contentious issue in Canadian customs valuation is whether transfer pricing adjustments made after importation—intra-group pricing revisions between related buyers and sellers—can be reflected retroactively in the value for duty declared for the imported goods. This is most acute for multinational importers subject to both tax transfer pricing policies and customs valuation under the Customs Act, and hinges on CBSA’s evolving administrative position and recent judicial decisions.
CBSA’s policy evolution Before 2018, the Canada Border Services Agency (CBSA) generally took the position that post-import transfer pricing adjustments, whether upward or downward, could be reflected in the customs value—provided the adjustment methodology was established prior to import and properly documented. However, in Customs Notice 16-20 (2016), the CBSA warned that it regarded post-entry downward adjustments with skepticism and often disallowed them.
In 2018, CBSA issued Customs Notice 18-22 and, in 2019, updated its core interpretive document—Memorandum D13-4-5, section 8 (“Transfer Pricing and Adjustments”). The agency’s clarified stance is:
- Only upward transfer pricing adjustments (resulting in additional dutiable value) may be reported and accounted for post-import, using either a voluntary correction or an adjustment to a previous declaration.
- Downward post-import price corrections are NOT accepted for reduction of value for duty unless the importer can show that the transfer pricing methodology and condition for adjustment were in place, and fixed, before importation. In the absence of such pre-import evidence, CBSA assumes the price paid or payable was the amount originally declared.
- For downward adjustments, the onus is on the importer to provide clear, contemporaneous proof that a pre-existing agreement provided for possible price reduction and that any revised price legitimately reflects the payment obligation in effect at the time of import. Otherwise, refunds or credits for duty are denied.
- If the upward or downward transfer price adjustment is routine (e.g., year-end true-up) but not fixed or objectively pre-determined before import, CBSA disallows it—citing the Federal Court of Appeal decision in PricewaterhouseCoopers LLP v. Canada (2015 FCA 97) and subsequent CITT jurisprudence (notably Bayer Inc. AP-2015-027, affirmed 2022).
Required evidence and compliance risk The documentation must include (a) the agreement or corporate policy in effect before import; (b) how the adjustment is objectively determined; and (c) correspondence or records showing the parties understood and agreed to the price mechanism pre-import. Mere after-the-fact accounting entries or transfer pricing studies prepared post-import will not suffice. If the original customs value was too low and a true-up requires additional payment, importers must submit a correction under section 32.2(2) of the Customs Act within 90 days of becoming aware.
Practical impact Routine transfer pricing true-ups can produce a compliance risk when the method is not established in advance. Importers unable to satisfy the documentation test for downward corrections must declare the higher initial invoice price as final, with no refund or reduction of duty, even if their tax reporting ultimately reduces the intercompany price.

Transaction value of identical goods (section 49) — fallback method and evidentiary requirements
When the primary transaction value method under section 48 of the Customs Act cannot be applied—typically due to absence of a qualifying sale for export, a failed related-party test, or insufficient information to affirmatively value assists or royalties—the law mandates the sequential fallback to section 49: the transaction value of identical goods. This method is often the first lifeline for importers whose primary documentation is lacking or who operate in industries with repetitive, standard goods imported under different purchasing chains.
Statutory structure and core requirements Section 49(1) of the Customs Act provides that if imported goods cannot be appraised under section 48, but identical goods have been imported into Canada at or about the same time in a sale for export to a purchaser in Canada, and those goods can be valued under the primary transaction value method, then the value for duty of the original goods is that transaction value of the identical goods, subject to quantifiable adjustments for differences in commercial level, quantity, and costs incurred for transportation and insurance (see s.49(1)(b); Valuation for Duty Regulations, SOR/86-792, s.3). “Identical goods” are defined in section 45(1) as goods that are the same in all respects, including physical characteristics, quality, and reputation, except for minor differences such as markings or packaging that do not alter the substance of the goods. Country of export and producer must also match unless differences have no impact on value.
The identical goods must have been exported at or about the same time (in practice, the CBSA generally uses a 90-day window, though the statute does not fix a strict limit) as the goods being appraised and must have been sold for export to a purchaser in Canada who is not related to the vendor, unless the CBSA accepts that the relationship did not influence price (the same related-party gate as section 48).
Adjustments and documentation Where valid identical-goods comparables are identified, adjustments to the reference transaction value are permitted only where they can be quantified based on objective and verifiable data. These include differences in:
- commercial level (e.g., wholesale vs. retail sales),
- quantity (different pricing tiers), and
- transportation, insurance, and associated costs if circumstances of shipment differ (Customs Act s.49(1)(b); Valuation for Duty Regulations).
All adjustments must be fully documented. The importer is expected to produce commercial invoices, shipping records, and, if relevant, contracts and correspondence establishing comparability.
When multiple eligible importations exist, the lowest transaction value among valid comparables is used (Customs Act s.49(2)). Where no sufficiently similar identically described goods are available, the law mandates a move to the transaction value of similar goods (section 50).
Burden of proof and typical pain points Under paragraph 152(3)(d) of the Customs Act, the burden of proof rests on the importer. CBSA Memorandum D13-5-1 specifies that officers will scrutinize whether any differences—producer, production batch, model year, or even packaging—could affect value. If documentation is missing or comparability cannot be demonstrated on objective grounds, the fallback is unavailable, and the valuation chain continues to section 50.
All facts and adjustments proposed by the importer should be treated as if destined for audit or review.

Transaction value of similar goods (section 50) — method, requirements, and documentation standard
Section 50 of the Canadian Customs Act prescribes the use of the transaction value of similar goods as the fourth method in the sequential customs valuation hierarchy—available only if valuation under transaction value (section 48), transaction value of identical goods (section 49), and (if comparable goods exist) methods above are unavailable. The method, grounded in Article 2 of the WTO Customs Valuation Agreement, is triggered when the imported goods cannot be valued under section 48 or 49, but there are contemporaneous imports of similar—not identical—goods supplied by the same producer or by a different producer in the same country, sold for export to Canada to a purchaser in Canada under comparable circumstances.
Definition of “similar goods” and qualifying conditions Section 45(1) of the Customs Act defines similar goods as goods that: (a) “although not alike in all respects, have like characteristics and like component materials which enable them to perform the same functions and to be commercially interchangeable with the goods being appraised”, and (b) were produced in the same country and by the producer of the goods being appraised, unless no such goods exist—in which case goods produced in the same country by a different producer may be used. This definition closely tracks the WTO Agreement (Annex I, Note to Article 15). The law prioritizes goods made by the same producer, but allows resort to other producers only when the same-producer test fails—an important sequence for supporting file documentation.
The similar-goods method applies only to goods exported to Canada at or about the same time as the goods being appraised. The CBSA generally interprets “at or about the same time” as within a 90-day window before or after the entry date, but this is not strictly fixed by statute; the closer, the better. The imported goods and the “similar” comparables must have been sold under conditions permitting use of the primary transaction value method (i.e., a bona fide sale for export, price paid or payable, purchaser in Canada, and proper documentation).
Permitted adjustments and evidentiary burden Section 50(1)(b) authorizes quantifiable adjustments to account for differences in commercial level, quantity, transportation/insurance, and other comparable factors affecting price—all on the same objective, verifiable-data basis as under section 49. The onus is squarely on the importer to (1) demonstrate that the selected similar goods meet the legal definition, (2) document each price adjustment, and (3) establish comparability to the CBSA’s satisfaction. Failure on any front—insufficient similarity, unverifiable pricing data, or lack of audit trail—precludes use of the method and forces progression to the next permissible valuation step (deductive value under section 51).
When multiple qualifying similar-goods comparisons are available, section 50(2) mandates that the lowest available transaction value among valid comparables must be used. This is tilted deliberately in the Crown’s favour—a practical caution for broker and client alike. CBSA Memorandum D13-6-1 provides extensive interpretive guidance, with case examples distinguishing “like characteristics,” material composition, function, and reputation—all must align for goods to be considered truly similar. Documentation requirements mirror those for identical-goods: full commercial invoices, technical data, marketing sheets, and—where necessary—expert opinion on functional equivalence.

CBSA valuation audit and verification procedures: Initiation, evidence, and importer rights
The Canada Border Services Agency (CBSA) regularly conducts audits (compliance verifications) to assess whether the value for duty declared by importers complies with the Customs Act and the Valuation for Duty Regulations. These audits are a core tool for detecting undervaluation, non-disclosed additions (such as unreported assists or royalties), and failures to apply the correct valuation method. The agency’s approach is risk-based, relying on risk indicators in import records, targeting by HS code, and random selection.
Audit initiation and triggers CBSA can initiate an audit at import, post-entry, or during a periodic compliance verification cycle. Audits may result from: (1) flagged anomalies detected at the time of entry, (2) referrals from other government departments, (3) patterns in HS codes associated with common valuation errors, or (4) random selection. The Directorate issues a request for information, such as a Form BSF373 (Request for Documentation), specifying the transactions or periods under review. In some cases, Form E311 (Customs Declaration Card) information or post-entry adjustment filings under section 32.2 of the Customs Act may also be reviewed as part of the audit.
Scope of the audit A valuation verification will assess correct application of the primary method (transaction value), scrutinize related-party pricing, additions and deductions under s.48(5), and the eligibility of references to fallback methods. Audit scope routinely extends to test sampling, inspection of sale contracts, invoices, proof of payments, royalty/licence agreements, transfer pricing studies, engineering/design work documentation, freight invoices, and supply chain records establishing the place of direct shipment. The CBSA may also request working papers demonstrating regional value content or origin for goods subject to trade agreements if value for duty is at issue.
Evidence standard and cooperation duty Importers must produce documents and information specified within the timeline on Form BSF373—usually 30 days from the request. Section 42 of the Customs Act authorizes CBSA’s demand for records kept under section 40, and section 43 grants the agency power to inspect premises or require information from third parties. Failure to provide records or to cooperate fully may result in reassessment, administrative monetary penalties (AMPs), or—if gross misstatement is found—seizure and ascertained forfeiture.
Importer rights and audit resolution If CBSA proposes to adjust the declared value, it must notify the importer in writing of the reasons and permit written representations before a final decision. Importers may appeal valuation determinations first through CBSA’s recourse process (sections 59–61), and if unsatisfied, by filing further appeals with the Canadian International Trade Tribunal, Federal Court of Appeal, or Federal Court, as applicable. Time limits for appeal are set by section 60(1) (90 days from the decision).

Valuation and allocation of assists: Statutory requirements and CBSA audit practice
Assists—the value of goods and services supplied by the purchaser free of charge or at reduced cost for use in producing imported goods—remain among the thorniest customs valuation issues in Canadian practice. The Customs Act and the Valuation for Duty Regulations require importers to identify, value, and apportion assists when calculating value for duty under both the transaction value and computed value methods, with strict documentary expectations enforced by CBSA.
Statutory test and categories of assists Under subparagraph 48(5)(a)(iii) of the Customs Act, additions to price paid or payable must include:
- (A) materials, components, and parts incorporated in the goods;
- (B) tools, dies, and moulds used in production;
- (C) materials consumed in production;
- (D) engineering, development, artwork, design work, plans, and sketches undertaken elsewhere than in Canada and necessary for production.
If supplied free or at reduced cost, these values are dutiable to the extent not already included in the invoice price. Engineering/design must be offshore in origin—Canadian-supplied services are excluded. Failure to capture any category risks reassessment and penalties.
Valuation and apportionment Section 4 of the Valuation for Duty Regulations sets the methodology. Valuation of materials and components is based on the price paid by the purchaser; tools and dies are apportioned over the production run benefiting from the free supply. Engineering and design work are valued at actual cost to the purchaser or, if unavailable, at the market value for such work. The allocation method must be reasonable—typically by number of units produced with the assist. Documentation must substantiate both the valuation approach and allocation formula. CBSA D13-3-12 and D13-3-11 specify that the importer must be able to trace each assist to corresponding import transactions.
Audit posture and evidentiary burdens CBSA expects importers to maintain detailed records—agreements, invoices, proof of delivery/use, engineering contracts—demonstrating the precise value and allocation of assists, and to disclose all assists in accounting declarations. Where an importer knows an assist exists but cannot quantify its value, use of the transaction value method is barred (Customs Act s.48(6)); fallback methods apply. In practice, lack of documentation or poor allocation methods is a common audit trigger, and the onus rests with the importer throughout (Customs Act s.152(3)(d)).

Subsequent proceeds additions under section 48(5)(a)(v): When are resale payments dutiable?
Subparagraph 48(5)(a)(v) of the Customs Act requires the value for duty to include “the value of any part of the proceeds of any subsequent resale, disposal or use of the goods by the purchaser that accrues or is to accrue, directly or indirectly, to the vendor.” This addition—known in practice as “subsequent proceeds”—is a recurrent compliance headache for importers using sales-based royalties, channel incentive schemes, or complex revenue-sharing arrangements.
Statutory test and scope The addition applies only if: (1) a portion of the proceeds of resale, disposal, or use of the imported goods will flow back to the vendor (directly or indirectly), and (2) that right to proceeds exists by virtue of the sale for export. The clause aims to prevent undervaluation when the vendor expects post-import payments, for example via sales-based royalties, commissions, or rebates tied to Canadian resale performance (as opposed to flat fees or lump-sum royalties, which are addressed separately under subparagraph 48(5)(a)(iv)). Payments that are wholly unrelated to the resale or use transaction—such as unrelated service fees or independent third-party arrangements—are not captured; CBSA Memorandum D13-4-13 draws this explicit distinction.
For the amount to be dutiable, there must be a discernible, reliable flow of funds, not a hypothetical or indirect market benefit. Common triggers flagged by CBSA audit include: (i) sales-based royalties paid to the supplier post-import; (ii) “retro-bonus” or “kickback” structures whereby the supplier receives additional payment per unit upon post-import resale; or (iii) contractually guaranteed minimum payments based on resale outcomes. The CBSA will disregard arrangements lacking contractual clarity or quantifiable data.
Timing and documentation requirements The importer must be able to specify, at the time of import, the quantum or method by which the subsequent proceeds can be determined. If the amount is unknown but calculable based on post-import sales, a reasonable estimate must be made and adjusted post-entry if necessary. Where full particulars cannot be provided, section 48(6) of the Act bars use of the transaction value method entirely, forcing fallback to identical/similar goods value or deductive/computed value.
Accepted documentation includes: supply contracts, channel agreements, royalty schedules, and post-entry accounting records showing payments to the vendor. The onus is on the importer to disclose and substantiate the full extent of any resale-linked amounts. CBSA Memorandum D13-4-13 gives illustrations and distinguishes dutiable proceeds from non-dutiable marketing or after-sale service fees when the benefit runs to unrelated third parties, not the vendor.
Case examples and audit approach CBSA auditors focus on:
- Sales-based royalties for branded products (e.g., a percentage of resale price paid back to the foreign rightsholder);
- Manufacturer incentives or rebates that require payment to the foreign vendor on subsequent resale by the Canadian importer;
- Cross-border supply chains where subsequent proceeds are netted or credited by an affiliate acting as collection agent on the vendor’s behalf.
In each case, failure to disclose may result in assessment of omitted duty and administrative penalties. Recapture clauses or floating payment terms must be monitored for changes after import, with voluntary correction obligations under section 32.2 if further payments accrue.
Section 48(5)(a)(v) has remained substantively unchanged since its introduction in the 1985 statute; no subsequent amendment has altered the core proceeds rule as of 2026.

Voluntary corrections and self-disclosure of value for duty errors (section 32.2)
Section 32.2 of the Customs Act creates a strict statutory regime obligating importers to voluntarily correct errors or omissions in value for duty declarations after accounting for goods—regardless of whether the mistake was detected internally, by a broker, or flagged in a post-release audit. This rule is pivotal for compliance management in Canada: the onus falls clearly on the importer to disclose and correct errors on its own initiative, with significant consequences for non-compliance.
Statutory triggers and timing Under section 32.2(1) of the Customs Act, when an importer "has reason to believe" that a declaration of origin, tariff classification, or value for duty was incorrect, they must “make a correction to the declaration” within 90 days. The obligation is triggered by the existence of information within the importer’s possession or control that gives reason to believe an error has occurred—this is broader than “actual knowledge.” The threshold is met not only when an importer discovers an explicit error (e.g., through a compliance review or advice from a broker or auditor), but also when objective data in the importer’s records (even if initially unrecognized) would lead a reasonable person to conclude that the declared value, origin, or classification was incorrect.
The 90-day period runs from the date the importer first has reason to believe—documented in internal correspondence, accounting records, or audit reports. Corrections are made by filing an updated B3 customs accounting document (B2 adjustment) and retaining supporting documentation. There is no materiality threshold: corrections must be made even for de minimis errors, though CBSA audit policy may prioritize significant adjustments for verification.
Limitations and exceptions Voluntary correction is only mandatory for adjustments resulting in duty or tax increases for goods accounted for within the previous four years (s. 32.2(2)), unless the CBSA is already actively auditing or has issued a verification letter covering the same issue. If a CBSA verification is underway and covers the relevant period and issue, further voluntary corrections on the points under audit are not accepted; the matter is handled through the audit determination process instead.
Consequences and penalty regime Failure to comply with the 90-day correction window can result in Administrative Monetary Penalties (AMPs) under the Customs Act, with penalty amounts escalating for repeated or systemic non-compliance (see CBSA AMPS Master Penalty Document, C082). Late or non-disclosed corrections may also carry interest charges on underestimated duty or tax liabilities. Importers who self-disclose outside of an audit may benefit from mitigated penalties but should not expect immunity unless very specific CBSA amnesty guidelines apply.
Documentation and best practice Best practice is to maintain contemporaneous records documenting the date the importer acquired "reason to believe" and the steps taken to investigate and submit corrections. The burden of proof, if challenged by CBSA, falls squarely on the importer.
