United Kingdom — Trade Remedies

The United Kingdom operates an independent trade-remedies regime under the Taxation (Cross-border Trade) Act 2018 ("TCTA 2018"), which came into force following the UK's departure from the EU. Section 13 of TCTA 2018 confers power on the Secretary of State to impose additional amounts of import duty to counteract three categories of unfair trade practices and import surges: dumping, subsidisation, and safeguard measures.

Schedule 4 to TCTA 2018 governs anti-dumping and countervailing duties (dumping and foreign subsidies causing injury to UK industry), while Schedule 5 addresses safeguard measures (increased imports causing serious injury to UK producers). These schedules set out the procedural and substantive framework for investigations, determinations, and imposition of remedies.

## The Trade Remedies Authority

The Trade Remedies Authority (TRA) is the independent body responsible for conducting trade-remedies investigations in the UK. The TRA was formally established under section 6 of the Trade Act 2021, which came into force on 1 June 2021. The TRA is constituted as a body corporate and is an executive non-departmental public body sponsored by the Department for Business and Trade.

The TRA's core function is to investigate whether new trade remedies are needed and to make recommendations to the Secretary of State. Under the framework in TCTA 2018 Schedules 4 and 5, the TRA conducts investigations, makes provisional and final affirmative or negative determinations (Schedule 4 paragraph 11; Schedule 5 paragraph 8), and recommends whether anti-dumping amounts, countervailing amounts, or safeguarding amounts (additional import duties) should be applied. The Secretary of State retains decision-making authority: the Secretary may accept or reject the TRA's recommendations, subject to a public-interest test (Schedule 4 paragraph 15(2); Schedule 5 paragraph 12(2)) and, for certain decisions, a requirement to lay a statement before the House of Commons explaining any rejection (Schedule 4 paragraph 20(4)(c); Schedule 5 paragraph 16(4)(c)).

## Three types of trade remedies

UK law recognises three WTO-compliant trade-policy tools:

1. Anti-dumping measures address goods imported into the UK at prices below their normal value in the country of export. Schedule 4 Part 1 sets out the framework for dumping investigations. Dumping occurs when goods are sold in the UK at a price lower than the normal value (typically the comparable price in the exporting country's domestic market), and the dumped imports cause or threaten material injury to a UK industry or prevent establishment of a UK industry (Schedule 4 paragraph 9).

1. Countervailing measures address imported goods that benefit from subsidies granted by foreign governments. Schedule 4 Part 2 governs subsidy investigations. The TRA assesses whether subsidised imports cause or threaten material injury to a UK industry (Schedule 4 paragraph 9, applied to subsidy cases).

1. Safeguard measures protect domestic industries against unforeseen surges of imports, regardless of whether those imports are unfairly traded. Schedule 5 establishes the framework for safeguarding investigations. Safeguard remedies are available when increased imports cause or threaten serious injury to UK producers (Schedule 5 paragraph 6), even absent dumping or subsidisation.

## The economic interest test

Before the TRA may recommend imposition of an anti-dumping amount, countervailing amount, or safeguarding amount, it must determine that the proposed remedy meets the economic interest test—a statutory requirement unique to UK trade-remedies law. Schedule 4 paragraph 25 (for dumping and subsidies) and Schedule 5 paragraph 23 (for safeguards) define the economic interest test. The TRA must be satisfied that applying the remedy is in the economic interest of the United Kingdom, having regard to all relevant economic factors, including the interests of UK producers, importers, users of the goods, and consumers. This test functions as a broader public-interest screen before duties are imposed.

## Implementing regulations

The procedural detail for each remedy type is set out in secondary legislation made under sections 13, 32, and 51 of TCTA 2018:

• The Trade Remedies (Dumping and Subsidisation) (EU Exit) Regulations 2019 (S.I. 2019/450) ("the D&S Regulations") implement Schedule 4, covering anti-dumping and countervailing-duty investigations, including determination of normal value, dumping margins, material injury, causation, and the economic interest test.

• The Trade Remedies (Increase in Imports Causing Serious Injury to UK Producers) (EU Exit) Regulations 2019 (S.I. 2019/449) ("the Safeguarding Regulations") implement Schedule 5, addressing safeguard investigations and the imposition of safeguarding amounts (additional duties or tariff-rate quotas).

## Scope: goods only, no services

Trade remedies under TCTA 2018 apply only to goods, not services. The UK trade-remedies framework does not extend to services. Remedies take the form of additional amounts of import duty (ad valorem or specific duties) or, in safeguard cases, tariff-rate quotas.

## Relationship to WTO agreements

UK trade-remedies law implements the UK's obligations as a WTO member. Schedule 4 paragraph 1 requires the TRA to have regard to the United Kingdom's international obligations, including:

• Article VI of the General Agreement on Tariffs and Trade (GATT 1994), which permits action against dumping and subsidisation;
• The WTO Anti-Dumping Agreement (Agreement on Implementation of Article VI of GATT 1994), which clarifies dumping investigation procedures and substantive standards;
• The WTO Agreement on Subsidies and Countervailing Measures (SCM Agreement), which regulates subsidy definitions and countervailing-duty investigations; and
• The WTO Agreement on Safeguards, which governs safeguard-measure conditions and procedural requirements.

## Transition from EU measures

Upon leaving the EU, the UK transitioned certain EU trade-remedy measures into UK law. Under Part 12 of the D&S Regulations and Part 9 of the Safeguarding Regulations, EU measures of interest to the UK were designated as "transitioned trade remedies" by Secretary of State determination notices. The TRA conducted transition reviews to determine whether each transitioned measure should be maintained, varied, or revoked to suit UK market circumstances (D&S Regulations regulation 76; Safeguarding Regulations regulation 48).

A UK trade-remedies investigation begins when the Trade Remedies Authority (TRA) accepts an application from a UK industry or, in exceptional cases, when the TRA initiates on its own motion. The Taxation (Cross-border Trade) Act 2018 Schedule 4 paragraph 9 (for dumping and subsidy investigations) and Schedule 5 paragraph 7 (for safeguards) set the statutory framework; procedural detail is in the Trade Remedies (Dumping and Subsidisation) (EU Exit) Regulations 2019 (S.I. 2019/450), regulations 50–53, and the Trade Remedies (Increase in Imports Causing Serious Injury to UK Producers) (EU Exit) Regulations 2019 (S.I. 2019/449).

## Who may apply

Under Schedule 4 paragraph 9(1)(a)(i), a dumping or subsidy investigation may be initiated on the basis of an application made by or on behalf of a UK industry in the goods concerned. A "UK industry" means all UK producers of like goods, or those producers whose collective output constitutes a major proportion of total UK production of like goods (Schedule 4 paragraph 6).

Regulation 52(2) of the D&S Regulations specifies the standing threshold: an application is treated as made by or on behalf of a UK industry when the TRA determines that it is supported by UK producers whose collective output constitutes at least 25 per cent of total UK production of the like goods, and is not opposed by other UK producers of the like goods whose collective output is greater than or equal to that percentage. In other words, support must reach 25% and opposition must not reach 25% of domestic production. If opposition equals or exceeds support, the TRA will reject the application for lack of standing.

Trade or business associations representing UK producers may file applications on behalf of their members, provided the 25% support threshold is met and opposition does not exceed that threshold.

## Application must be submitted via the Trade Remedies Service

Regulation 52(4) permits the TRA to reject an application if it is not made via the TRA's case management system—the Trade Remedies Service (accessible at trade-remedies.service.gov.uk). The online portal is the mandatory channel; paper or email applications outside the system may be refused.

Before submitting a formal application, UK producers may consult the Trade Remedies Advisory Service (formerly the Pre-Application Office), which provides informal guidance on completing the application form and clarifies data requirements. The Advisory Service is independent from the TRA's investigation teams: staff who review draft applications take no part in the subsequent assessment or case determination once an investigation is initiated, and they do not share pre-application information with case teams. Engagement with the Advisory Service is voluntary; applicants may file directly if they prefer.

## Evidence and data requirements

The TRA examines the accuracy and adequacy of the information in the application to determine whether it justifies initiation (regulation 52(1)). Applications for dumping and subsidy investigations must demonstrate:

1. Dumping or subsidisation. Evidence that the goods are being sold in the UK at prices below normal value (for dumping), or that a countervailable subsidy has been granted for the goods' manufacture, production, export, or transport (for subsidies). Applicants typically provide pricing data, invoice samples, cost breakdowns, and public subsidy notices.

1. Injury to the UK industry. Data showing material injury (or threat of material injury) to the UK industry, or material retardation of the industry's establishment (Schedule 4 paragraph 5). This includes production volume, sales, capacity utilisation, employment, profitability, market share, prices, and trends over approximately five years.

1. Causation. Evidence that the dumped or subsidised imports are causing (or threatening to cause) the injury, as distinct from other factors (Schedule 4 paragraph 9). Correlation of import volumes, prices, and domestic-industry performance is critical.

1. Market-share requirement. Under regulation 51, the TRA will not initiate unless the applicant UK industry's share of the UK market for the goods is at least 1 per cent, or such higher share as the TRA considers appropriate for the particular goods and market. If the domestic industry is de minimis, the application will be rejected.

Safeguard applications require analogous evidence—showing increased imports and serious injury—under Schedule 5 and the Safeguarding Regulations.

## Assessment and confidentiality during the pre-initiation phase

The TRA does not publicise an application until it has determined to initiate the investigation (regulation 53(1)). While assessing the application, the TRA may request additional information from the applicant or from other parties relevant to the application. Applicants may withdraw an application at any time before the notice of initiation is published; if withdrawn before publication, the application is treated as not having been made and will not appear on the public record (regulation 50(4)).

The TRA may reject an application if it does not satisfy the requirements in regulation 50 (the standing and market-share thresholds) or regulation 52 (adequacy of evidence), unless the TRA has expressly waived a particular requirement (regulation 52(3)).

## Initiation decision and publication

If the TRA accepts the application, it notifies the Secretary of State of its decision to initiate (Schedule 4 paragraph 9(5) and (6)). The TRA then publishes a notice of initiation online through the Trade Remedies Service, notifies interested parties (including the governments of the countries subject to the investigation), and—in subsidy cases—invites those governments to participate in consultations (Schedule 4 paragraph 9(5)(d) and (6)(c); regulation 65).

The notice of initiation must contain the information specified in Schedule 2 to the D&S Regulations, including the description of the goods, the countries of origin or export, a summary of the factors on which the allegation of dumping or subsidisation is based, and a summary of the injury evidence.

For safeguard investigations, initiation triggers additional WTO notification and consultation requirements performed by the UK Government (Schedule 5).

## Own-initiative (ex officio) investigations

Under Schedule 4 paragraph 9(1)(b), the TRA may initiate a dumping or subsidy investigation on its own initiative if it appears that the conditions for imposing an anti-dumping or countervailing amount may be met. This discretionary power permits the TRA to act even without an industry application, though in practice own-initiative cases are rare. The TRA must still be satisfied that there is sufficient evidence of dumping or subsidisation, injury, and causation before initiating ex officio.

## Rejection and recourse

If the TRA rejects an application, the applicant has no automatic right to a formal appeal at that stage; the rejection is a preliminary decision rather than a final determination. However, the applicant may submit a revised application addressing the deficiencies identified by the TRA, or seek judicial review of the rejection decision on public-law grounds (irrationality, procedural unfairness, or error of law).

A UK trade-remedies investigation from initiation to final determination operates under statutory and WTO-mandated timelines that shape both the TRA's procedural calendar and the commercial risk-management decisions of importers, exporters, and domestic producers. The WTO Anti-Dumping Agreement Article 5.10 establishes the outer constraint: investigations shall, "except in special circumstances, be concluded within one year, and in no case more than 18 months, after their initiation." Schedule 4 paragraph 1 of the Taxation (Cross-border Trade) Act 2018 requires the TRA to "have regard to" the United Kingdom's WTO obligations, including the Anti-Dumping Agreement and the WTO Agreement on Subsidies and Countervailing Measures; that incorporation brings the 12-month target and the 18-month ceiling into the UK framework as binding constraints.

The TRA publishes an indicative timeline for each new investigation, transition review, or other review on the public file for the relevant case early in the investigation. The timeline includes target dates for the provisional affirmative determination (if any), the Statement of Essential Facts, and the final recommendation to the Secretary of State. These indicative timelines are not binding statutory deadlines, but the TRA is expected to update the case file and notify the Secretary of State when it cannot meet its own published milestones. If the TRA determines that it will exceed the 18-month WTO maximum, it must provide an explanation directly to the Secretary of State in support of the UK's WTO compliance responsibilities.

In practice, the TRA targets 11 to 13 months for the completion of a dumping or subsidisation investigation from initiation through final recommendation to the Secretary of State. Safeguarding investigations typically run on a slightly shorter timeline. Actual duration varies with case complexity, the number of sampled exporters, the need for verification visits, and the volume of information submitted by interested parties and contributors.

## Provisional measures: imposition and duration

Where a dumping or subsidisation investigation has advanced to the point that the TRA can make a provisional affirmative determination — a preliminary finding that goods have been or are being dumped or subsidised, that a UK industry is suffering injury, and that causation exists — the TRA may recommend to the Secretary of State that importers be required to give a guarantee (cash deposit, bond, or bank guarantee) for the estimated anti-dumping or countervailing amount on all imports of the goods during the investigation. Schedule 4 paragraph 13(3) and (4) permit this recommendation only if the TRA is satisfied that requiring a guarantee is necessary to prevent injury being caused during the investigation to the UK industry and that the provisional remedy meets the economic interest test. The provisional remedy does not impose a definitive duty; instead, it secures the estimated liability so that, if the final determination is affirmative, importers can be held accountable for duties accrued during the provisional period. If the final determination is negative, or if the Secretary of State rejects the TRA's final recommendation, the guarantee is released and no duty is collected.

The period of a provisional remedy — the period during which the guarantee requirement applies — is subject to statutory maxima set out in the Trade Remedies (Dumping and Subsidisation) (EU Exit) Regulations 2019 (S.I. 2019/450), regulation 90 and the relevant paragraphs of Schedule 4 to TCTA 2018. For dumping investigations, the period of the provisional remedy must not exceed 6 months; for subsidisation investigations, it must not exceed 4 months. The period begins the day after publication of the Secretary of State's notice accepting the TRA's recommendation (or, if later, the day after the 60th day following the date of initiation of the investigation). The period of the provisional remedy ceases automatically when the investigation terminates, whether by final determination, undertaking, or withdrawal.

Under certain circumstances, the Secretary of State may extend the period of a provisional remedy in a dumping investigation. Regulation 90 provides that the TRA may, on its own initiative or at the request of an interested party, recommend an extension if satisfied that such extension is necessary to prevent injury during the investigation and meets the economic interest test. However, even with an extension, the combined period of the provisional remedy plus any extension is constrained by the overall investigation deadline: the investigation as a whole must conclude within the 12-month target or the 18-month WTO maximum. The TRA and the Secretary of State manage the extension decision to ensure that sufficient time remains for the final determination stage and for parties to submit comments on the Statement of Essential Facts.

Safeguard investigations operate under a parallel but distinct regime established by Schedule 5 to TCTA 2018 and the Trade Remedies (Increase in Imports Causing Serious Injury to UK Producers) (EU Exit) Regulations 2019 (S.I. 2019/449). The TRA may recommend a provisional safeguarding remedy (a provisional safeguarding amount, provisional suspension of tariff rate reduction, or provisional tariff rate quota) under Schedule 5 paragraph 11. The WTO Agreement on Safeguards does not prescribe a maximum investigation period as explicitly as the Anti-Dumping Agreement does, but UK practice and WTO notification obligations encourage timely completion. Safeguarding investigations are typically faster than dumping or subsidy investigations because they do not require company-specific dumping-margin or subsidy calculations for multiple overseas exporters; instead, the TRA examines import-volume trends, price effects, and serious injury to the UK industry on an aggregate basis.

## Registration period and questionnaire issuance

The TRA sets a registration period at the outset of the investigation during which interested parties (UK producers, importers, overseas exporters, governments of the countries under investigation, and trade or business associations) and any other person may make themselves known to the TRA and register to participate. Regulation 54 of the Dumping and Subsidisation Regulations requires the TRA to issue questionnaires "as far as practicable" to all interested parties who registered during the registration period, to all UK producers, importers, and overseas exporters identified in the application, and to all contributors who registered. Parties who register after the end of the registration period may still be included in any sample used by the TRA for dumping-margin or subsidy-amount calculations, though there is no guarantee.

Questionnaire responses form the evidentiary foundation for the TRA's determination. The TRA typically allows parties at least 30 days to complete and submit questionnaire responses, although regulation 55(4) permits the TRA to set a shorter period "where the circumstances of the case so require" — subject to a minimum of 21 days in most circumstances. Late or incomplete responses can lead the TRA to apply facts available under regulation 60, which may result in a less favourable dumping margin, subsidy amount, or injury finding for the non-cooperating party.

## Statement of Essential Facts and final recommendation

Before making a final affirmative or final negative determination, the TRA must publish a Statement of Essential Facts (SEF) that sets out the intended final determination, a summary of the facts considered, the facts that formed the basis of the intended determination, and the TRA's analysis (regulation 62). The SEF serves as the TRA's draft decision. Interested parties and contributors typically have at least two weeks to submit comments on the SEF, though the TRA determines the appropriate comment period based on the complexity of the case. The SEF comment phase is the final opportunity for parties to correct factual errors, respond to claims by other parties, and challenge the TRA's legal or economic analysis before the TRA finalises its recommendation.

Following the SEF comment period, the TRA makes its final determination and, if affirmative, formulates a recommendation to the Secretary of State on the type, level, and duration of the remedy (or alternative remedies if different options meet the economic interest test). The TRA must notify the Secretary of State of the recommendation. The Secretary of State then has discretion to accept or reject the recommendation, subject to the public-interest test in Schedule 4 paragraph 15(2) for dumping and subsidy investigations and Schedule 5 paragraph 12(2) for safeguarding investigations. If the Secretary of State rejects a TRA recommendation to impose an anti-dumping, countervailing, or safeguarding amount, the Secretary must lay a statement before the House of Commons setting out the reasons for the rejection.

## Judicial review and reconsideration

Under the Trade Remedies (Reconsideration and Appeals) (EU Exit) Regulations 2019 (S.I. 2019/910), interested parties may apply to the TRA for reconsideration of certain decisions, including the rejection of an application, a determination to terminate an investigation, and (after the Secretary of State has made a decision following an investigation) the Secretary of State's acceptance or rejection of a TRA recommendation. If reconsideration is refused or if the reconsidered decision is still adverse, parties may appeal to the Upper Tribunal on a point of law. Appeals must be brought within strict time limits (generally 30 days from the date of the decision). The Upper Tribunal may affirm, set aside, or remit the decision to the TRA or the Secretary of State for reconsideration. Judicial review in the High Court is also available for public-law challenges (irrationality, procedural unfairness, or error of law), though the reconsideration-and-appeal route under the 2019 Regulations is the primary statutory mechanism for challenge.

## Duration of definitive measures and expiry reviews

Definitive anti-dumping amounts, countervailing amounts, and safeguarding amounts (once imposed by the Secretary of State) remain in force for a specified period, typically up to five years from the date of application. Schedule 4 paragraph 17 and Schedule 5 paragraph 16 permit the TRA to recommend a shorter period if it considers that a measure of less than five years is more appropriate. The five-year maximum aligns with the WTO Anti-Dumping Agreement Article 11.3 requirement that duties "shall be terminated on a date not later than five years from their imposition" unless an expiry review (commonly called a "sunset review") determines that "the expiry of the duty would be likely to lead to continuation or recurrence of dumping and injury." UK law incorporates this sunset-review mechanism in regulation 70 of the Dumping and Subsidisation Regulations and regulation 35 of the Safeguarding Regulations. UK producers or other interested parties must apply to the TRA for an expiry review; the application must be submitted within a specified window (typically ending no later than three months before the measure is due to expire). If the TRA conducts an expiry review and determines that expiry would be likely to lead to continuation or recurrence of dumping (or subsidisation) and injury, the measure may be extended for a further period, again subject to a maximum of five years.

The combination of the WTO-mandated 18-month investigation ceiling, the UK statutory maxima on provisional-remedy periods, and the mandatory expiry-review framework ensures that UK trade remedies operate within defined temporal boundaries and are subject to periodic re-examination. Parties planning to participate in a UK trade-remedies investigation should monitor the TRA's published indicative timeline, observe the registration-period and questionnaire-response deadlines, and reserve capacity to submit detailed comments on the Statement of Essential Facts—since missing any of these procedural milestones can materially prejudice a party's ability to shape the final determination.

The dumping margin is the numerical heart of every anti-dumping investigation — the difference between the export price and the normal value of the goods, expressed as a percentage of the export price. The Trade Remedies (Dumping and Subsidisation) (EU Exit) Regulations 2019 (S.I. 2019/450), Part 2, sets out the UK methodology for calculating this margin; it follows WTO Anti-Dumping Agreement Article 2 and incorporates the TRA's operational guidance. A dumping margin below 2 per cent is considered de minimis and will lead to termination of the investigation; a finding of dumping requires the margin to meet or exceed that threshold.

## Step one: determining normal value

The normal value of the goods is the baseline for comparison — the price that represents the true commercial value absent dumping. Regulation 7(1) defines normal value as the comparable price of like goods when sold in the ordinary course of trade in the domestic market of the exporting country or territory. This is the default method: if the overseas exporter sells like goods domestically at arm's-length prices in ordinary commercial transactions, those domestic sales provide the normal value.

Regulation 9 defines the "ordinary course of trade" threshold. Sales are not in the ordinary course of trade — and thus excluded from the normal-value calculation — when they are made at prices below the per-unit cost of production plus SG&A and either (a) were made over an extended period (normally one year) in substantial quantities (at least 20 per cent of the exporter's volume of profitable sales of the like goods), or (b) were at prices that do not permit recovery of all costs within a reasonable period. Below-cost sales that pass these volume and duration thresholds are disregarded; the TRA bases normal value on the remaining profitable domestic sales.

When the exporter has no domestic sales, or when domestic sales are not in the ordinary course of trade, or when a particular market situation exists in the domestic market such that those sales do not permit a proper comparison, the TRA applies an alternative methodology under regulation 8:

1. Third-country price (regulation 10): The TRA may determine normal value based on the representative price of like goods when sold for consumption in an appropriate third country or territory — typically a country with a comparable market structure and at a similar level of economic development, where the exporter (or other producers) sell like goods in meaningful volumes.

1. Constructed normal value (regulations 11 and 12): The TRA constructs normal value by summing:

• the cost of production of the goods in the country of origin (regulation 11), calculated on a per-unit basis for materials, labour, energy, and other production inputs during the period of investigation; plus
• a reasonable amount for administrative, selling, and general (SG&A) costs (regulation 12(2)(a)); plus
• a reasonable amount for profit (regulation 12(2)(b)).

SG&A and profit are typically based on the exporter's actual data for profitable sales of like goods in the domestic market, or — if no such sales exist — on the weighted-average SG&A and profit of other producers or exporters in the same country for sales of goods in the same general category. When no domestic-market or same-country benchmark is available, the TRA may use any reasonable method, including reference to sales of the like goods when exported to a third country.

1. Non-market-economy methodology (regulation 14): For imports from a country the TRA determines is not operating on market-economy principles — typically because (a) the state owns or controls a significant part of the means of production, or (b) there is a complete or substantially complete monopoly of trade and substantially all domestic prices are fixed by the government — the TRA may disregard the exporter's domestic prices and costs entirely. Instead, the TRA constructs normal value using the costs of production and sale of like goods in an appropriate market-economy third country (a "surrogate country"), chosen on the basis of comparable economic development and production of comparable merchandise. This methodology addresses the distortion that state intervention introduces into price and cost data.

## Particular market situation

Regulation 7(3) and (4) permit the TRA to find that a particular market situation exists in the exporting country's domestic market, making domestic sales unsuitable for normal-value determination even when those sales are otherwise in the ordinary course of trade. Regulation 7(4) provides a non-exhaustive list of circumstances that may constitute a particular market situation:

• barter trade or non-commercial arrangements covering a significant part of the domestic market;
• hyperinflation, state trading, or other macroeconomic distortions;
• government intervention in the domestic market for the like goods or in markets for significant inputs (e.g., raw materials, energy), resulting in artificially low or high sales prices.

When the TRA finds a particular market situation, it moves to the third-country price or constructed-value methodology under regulation 8.

## Step two: determining the export price

Regulation 15 governs the export price — the price actually paid or payable for the goods when sold for export to the United Kingdom. The default is the transaction price charged by the overseas exporter to the first independent UK buyer, adjusted ex-works (i.e., excluding freight, insurance, UK import duty, and other post-export costs).

When there is no export price or when the export price is unreliable because the exporter and the importer are associated or there is a compensatory arrangement (e.g., barter, offset, or reciprocal-purchase agreements), the TRA may construct the export price under regulation 15(2). The constructed export price is the price at which the imported goods are first resold to an independent buyer in the UK, minus:

• UK import duties and taxes;
• costs incurred between importation and resale (transport, warehousing, selling costs); and
• a reasonable margin for SG&A and profit.

This constructed price approximates the ex-works export price absent the transfer-pricing or compensation distortion.

## Step three: fair comparison and adjustments

Regulation 16 requires the TRA to ensure a fair comparison between the normal value and the export price. The comparison must be made at the same level of trade (ordinarily ex-works or ex-factory) and at as nearly as possible the same time. Regulation 13 permits (and in many cases requires) the TRA to make adjustments to the normal value or the export price (or both) to account for differences that affect price comparability and are demonstrated by verifiable evidence, including:

• Physical characteristics of the goods (if the exported goods differ in specification, grade, or model from the domestic like goods);
• Import charges and indirect taxes (regulation 13(2)(a)); the TRA adjusts normal value downward to exclude internal taxes (e.g., VAT) levied on domestic sales, and adjusts the export price to exclude UK import duty and taxes to bring both to a comparable tax-free ex-works basis;
• Discounts, rebates, and allowances granted to customers, if directly linked to the sales in question;
• Commissions paid in the export market but not in the domestic market, or vice versa (regulation 13(2)(e)); when a commission is paid in only one market, the TRA may also adjust for the relevant selling expenses incurred in the other market;
• Level of trade (regulation 13(2)(d)): if the exporter sells to different categories of customer domestically (e.g., wholesalers) versus export (e.g., retailers), the TRA adjusts for the difference in margins and selling costs associated with each distribution channel;
• Transportation, insurance, handling, and packing costs (regulations 13(2)(b) and (c)); the TRA adjusts both prices to ex-works to remove freight, insurance, packing for shipment, and handling charges incurred after the goods leave the factory gate;
• Credit terms and payment dates (regulation 13(2)(f)); differences in credit periods or payment method (e.g., letter of credit versus open account) may warrant an adjustment for the time-value of money or for the cost of credit insurance.

The burden is on the party claiming the adjustment to demonstrate that the difference affects price comparability and to quantify the adjustment with documentary evidence (invoices, contracts, cost accounting records). The TRA will not make speculative or unsupported adjustments.

## Comparison methodology: weighted-average-to-weighted-average, transaction-to-transaction, and asymmetric (targeted-dumping) methods

Regulation 17 sets out the permissible methodologies for comparing normal value and export price once both have been determined and adjusted for fair comparison:

1. Weighted-average to weighted-average (regulation 17(2)(a)): The TRA compares a weighted-average normal value with a weighted-average of prices of all comparable export transactions to the UK during the period of investigation. This is the default method and is used in the great majority of UK dumping investigations. For each Product Control Number (PCN) — a code that groups goods by key physical and commercial characteristics — the TRA calculates a single weighted-average normal value and a single weighted-average export price, applies adjustments, and derives the dumping margin for that PCN. The overall dumping margin for the exporter is the quantity-weighted or value-weighted average across all PCNs.

1. Transaction-to-transaction (regulation 17(2)(b)): The TRA compares the normal value and the export price on an individual-transaction basis, matching each export sale to a comparable domestic sale (or to the constructed normal value for goods of the same PCN) and calculating the dumping amount for each pair of transactions. The overall margin is the sum of the dumping amounts (ignoring negative amounts, i.e., transactions where export price exceeded normal value) divided by the total value of exports. This method is rarely used in UK practice; it is appropriate when the exporter's pricing is highly heterogeneous and transaction-level matching better reflects the pattern of dumping.

1. Asymmetric comparison — weighted-average normal value to individual export transactions (regulation 17(3) and (4)): The TRA may compare a weighted-average normal value to the prices of individual export transactions if the TRA determines that a pattern of export prices exists that differs significantly among different purchasers, regions, or time periods in the UK, and it is not possible to take appropriate account of those differences using the weighted-average or transaction-to-transaction method. This "targeted dumping" or "W-T" methodology is designed to capture situations in which an exporter dumps selectively — for example, offering deep discounts to certain UK buyers or in certain UK regions or during certain months, while maintaining higher (non-dumped) prices to other buyers. The asymmetric comparison prevents averaging of high and low export prices from masking the dumping pattern. Regulation 17(4) requires the TRA to apply this method only when the conditions are met and to explain its reasoning; the method is exceptional and must be justified by evidence of targeted pricing behaviour.

## Currency conversion

Regulation 18 addresses currency conversion when the normal value and the export price are denominated in different currencies. The TRA uses the rate of exchange on the date of sale (normally the date of the sales contract, purchase order, or — if those determine different terms — the invoice date). The TRA will ordinarily use the exchange rate the exporter itself used for accounting purposes for the sales in question, unless that rate is shown to be unreliable or manipulated. If daily or transaction-specific rates are not available, the TRA may use a monthly or quarterly average exchange rate for the period in which the sales occurred.

## Product Control Numbers (PCNs) and like-goods matching

The TRA assigns Product Control Numbers to sub-categories of the goods under investigation based on the main physical, technical, and commercial characteristics that differentiate models, grades, or specifications within the scope of the investigation (e.g., for steel products: thickness, width, coating type, grade; for chemicals: purity, packaging size, form). During the dumping-margin calculation, the TRA matches each PCN of exported goods to the same PCN (or the most closely comparable PCN) of like goods sold domestically, ensuring that the comparison is between genuinely comparable merchandise. When an exporter has no domestic sales of a particular PCN, the TRA constructs the normal value for that PCN using the cost-buildup method under regulations 11 and 12, applying the exporter's actual per-unit production cost for that PCN plus the exporter's average SG&A and profit for all like goods (or, if none, a benchmark from other producers).

## Output: the dumping margin and the de minimis threshold

The final dumping margin for each overseas exporter is expressed as a percentage of the export price. Regulation 4(2) defines a dumping margin of less than 2 per cent, expressed as a percentage of the export price, as de minimis — negligible. If the TRA determines that the dumping margin for goods from a particular country is less than 2 per cent, the investigation must be terminated immediately with respect to those goods under Schedule 4 paragraph 10(2) of the Taxation (Cross-border Trade) Act 2018. Similarly, if the volume of dumped imports from a country is negligible (defined in regulation 3 as less than 3 per cent of total UK imports of like goods, unless imports from several countries individually below 3 per cent collectively exceed 7 per cent), the investigation terminates.

The dumping margin is one of two ceilings on the level of any anti-dumping amount the TRA may recommend. Under the lesser-duty rule (regulation 36 and Schedule 4 paragraph 18), the TRA must recommend the lower of (a) the dumping margin or (b) the injury margin (the amount required to remove the injury to the UK industry). The injury margin is calculated separately, based on a comparison of the UK industry's target price (a non-injurious price that would allow the UK industry to cover costs plus a reasonable profit) and the landed price of the dumped imports. In most UK cases, the recommended anti-dumping amount is set at the injury margin if it is lower than the dumping margin, ensuring that the duty removes the injury without over-protecting the domestic industry.

The economic interest test (EIT) is the United Kingdom's statutory public-interest screen for trade remedies — a mandatory assessment, unique to UK law, that asks whether imposing an anti-dumping amount, countervailing amount, or safeguarding amount is in the economic interest of the United Kingdom when the interests of all affected UK stakeholders are weighed. The test is codified in Schedule 4 paragraph 25 of the Taxation (Cross-border Trade) Act 2018 (TCTA 2018) for dumping and subsidy investigations, and in Schedule 5 paragraph 23 for safeguard investigations. Every TRA recommendation to impose a trade remedy must include the TRA's determination of whether the proposed measure meets the economic interest test, and the Secretary of State must in turn consider the test before accepting or rejecting the TRA's recommendation.

The EIT is not required by WTO law. The WTO Anti-Dumping Agreement, the SCM Agreement, and the Agreement on Safeguards permit but do not mandate public-interest or economic-interest assessments. The UK's decision to embed the EIT in primary legislation reflects a policy judgment that trade remedies should protect domestic producers from unfair trade only when the broader economic costs — to importers, downstream manufacturers, consumers, and the competitive environment — do not outweigh the benefits of removing the injury to the UK industry. Other jurisdictions that conduct analogous assessments include the European Union (under its "Union interest" test), Canada (optional public-interest test), New Zealand, and Brazil; however, the UK test is mandatory for dumping and subsidy cases and is arguably more transparent and rule-bound than those in other systems.

## Statutory definition and the five mandatory factors

Schedule 4 paragraph 25(2) defines the economic interest test as met "if the application of the remedy is in the economic interest of the United Kingdom." Paragraph 25(4) and Schedule 5 paragraph 23(3) set out five categories of economic factors that the TRA and the Secretary of State must take into account "so far as relevant" when conducting the assessment:

1. The injury caused to the UK industry by the dumped or subsidised goods (or, in safeguard cases, by the increased imports) and the benefits to that industry in removing that injury. This factor captures the positive impact of a remedy on the affected UK producers: restoration of market share, price recovery, return to profitability, preservation of employment, and prevention of industry exit or retardation of a new industry's establishment. The TRA compares injury indicators (capacity utilisation, sales volumes, profit margins, employment levels) in a scenario with the remedy versus a scenario without it.

1. The economic significance of affected industries and consumers in the United Kingdom. The TRA evaluates the size, turnover, employment, and contribution to GDP of the UK industry that would be protected, as well as the economic significance of importers, downstream manufacturers (users of the goods as inputs in their own production processes), and end consumers. If the protected industry is small but the downstream users are systemically important — for example, if the goods are critical inputs for automotive, aerospace, or pharmaceutical manufacturing — this factor may weigh against imposing a remedy.

1. The likely impact on affected industries and consumers in the United Kingdom. The TRA assesses both positive and negative impacts. For UK producers of the like goods, the impact is typically positive: higher prices, improved margins, increased production. For importers and downstream users, the impact may be negative: higher input costs, reduced product availability if overseas suppliers stop serving the UK market, potential loss of competitiveness in export markets if their input costs rise. For consumers, the TRA considers whether the remedy will lead to measurably higher retail prices, and whether those price increases will disproportionately affect lower-income households or particular demographic groups (including groups with protected characteristics under the Equality Act 2010).

1. The likely impact on particular geographic areas, or particular groups, in the United Kingdom. The TRA examines whether the remedy would have concentrated regional effects — for example, if the UK industry is concentrated in one part of the country (such as the Midlands or the North East) while downstream users are concentrated elsewhere, or if a particular supply chain (for instance, the steel supply chain for automotive or construction) would be disrupted. The TRA may seek information from devolved administrations (Scotland, Wales, Northern Ireland) and local authorities to understand regional distributional effects.

1. The likely consequences for the competitive environment, and for the structure of markets for goods, in the United Kingdom. The TRA assesses whether the remedy would entrench a dominant UK producer, reduce the number of suppliers in the UK market, or otherwise harm competition. Conversely, the TRA considers whether the absence of a remedy would lead to the exit of the last remaining UK producer, thereby reducing competition in the long run and increasing UK dependence on overseas suppliers that may exercise market power once domestic competition is eliminated. The assessment is primarily qualitative and considers both short-term and long-term effects on market structure.

In addition to these five mandatory factors, Schedule 4 paragraph 25(4)(b) and Schedule 5 paragraph 23(3)(b) require the TRA and the Secretary of State to "take account of such other matters" as they consider relevant. This catch-all provision allows the TRA to weigh considerations specific to the particular goods, industry, or supply chain in question — for example, national-security implications of supply-chain resilience, environmental costs or benefits of shifting production, or the UK's international obligations under free-trade agreements.

## Presumption in dumping and subsidy cases; no presumption in safeguards

A critical procedural difference distinguishes dumping and subsidy investigations from safeguard investigations. For anti-dumping and countervailing-duty cases, Schedule 4 paragraph 25(3) establishes a presumption that the economic interest test is met unless the TRA or the Secretary of State is satisfied that the application of the remedy is not in the economic interest of the United Kingdom. In other words, once the TRA has determined that goods are dumped or subsidised, that a UK industry is suffering material injury, and that causation exists, the economic interest test is rebuttably presumed to be satisfied; the burden is on parties opposing the remedy — typically importers, downstream users, or consumers — to demonstrate that the costs of the remedy outweigh its benefits.

For safeguard investigations, by contrast, Schedule 5 paragraph 23 contains no such presumption. The TRA must affirmatively determine, based on the evidence in the record, that the proposed safeguarding remedy is in the economic interest of the United Kingdom. The absence of a presumption reflects the different nature of safeguard measures: safeguards address import surges irrespective of unfair trade, and they restrict imports that may themselves be fairly traded and competitively priced; accordingly, UK law requires a more demanding assessment of whether the protection is justified.

## When the TRA conducts the EIT

The TRA is required to conduct the EIT in the following circumstances:

• In a new dumping or subsidy investigation, if the TRA makes a provisional affirmative determination or a final affirmative determination. The TRA's provisional and final recommendations to the Secretary of State must state whether the TRA considers that the proposed provisional or definitive remedy meets the economic interest test.

• In a new safeguard investigation, if the TRA makes a provisional or final affirmative determination.

• In an expiry review (sunset review), if the TRA recommends extending the duration of an existing measure. The TRA must determine whether the extension meets the EIT.

• In certain other reviews where the TRA proposes to vary the measure in a way that extends its duration or increases its scope. The TRA has discretion to conduct the EIT in mid-term or scope reviews even when not strictly required.

• In an investigation in light of an international dispute decision or an early review initiated by the Secretary of State, if the Secretary of State consults the TRA and determines that an EIT should be conducted as part of that investigation.

The TRA does not conduct the EIT if it makes a negative determination (no dumping, no injury, or no causation), because there is no remedy to assess. Similarly, if the TRA has already conducted an EIT during the original investigation, a subsequent review may rely on the original EIT assessment supplemented by data on the measure's actual economic impact since it was imposed, rather than conducting a fresh stand-alone EIT from scratch.

## Data sources and evidence

The TRA's EIT assessment draws on multiple sources of evidence, including:

• Questionnaire responses from UK producers, importers, overseas exporters, and downstream users submitted during the investigation.

• Business and consumer surveys commissioned by the TRA to collect evidence from upstream suppliers, downstream manufacturers, distributors, and end consumers about the expected impact of the remedy on input costs, product availability, retail prices, and purchasing decisions.

• Written submissions from interested parties and contributors. Importers, users, and consumer groups may submit economic analyses, market studies, supply-chain maps, and price-impact modelling to support their positions.

• Publicly available data from HM Revenue & Customs (HMRC) trade statistics, the United Nations Comtrade database, the Office for National Statistics (ONS) (industry output, employment, inflation data), industry publications, and international trade databases.

• Information from other government departments and devolved administrations when the TRA considers that a remedy may have significant regional, sectoral, or national-security implications.

The TRA is required to critically assess and verify the data and evidence it relies upon, using independent sources where practicable. All submissions and data are subject to the TRA's verification procedures and may be disregarded if they cannot be substantiated.

## Outcome: what happens if the EIT is not met

If the TRA determines that no form of remedy would meet the economic interest test, the TRA's preferred recommendation to the Secretary of State must be that no measure be imposed, even if dumping (or subsidisation or increased imports) and injury have been found. In such cases, the TRA terminates the investigation with a recommendation of no remedy.

When the TRA concludes that a remedy is justified but that different forms of remedy would have different economic impacts, the TRA may recommend alternative options to the Secretary of State. Under the statutory framework and the TRA's operational guidance, the TRA must ordinarily provide at least one alternative option: a 5-year ad valorem duty (for dumping or subsidy cases) or a 4-year ad valorem duty (for safeguards). The TRA may also recommend a second alternative if it considers that another form of remedy — for example, a shorter duration, a different duty structure (specific duty, price undertaking, tariff-rate quota), or an exemption for certain end uses or importers — would better balance the competing interests. The Secretary of State then selects one of the recommended options (or rejects all of them under the public-interest override in Schedule 4 paragraph 15(2) or Schedule 5 paragraph 12(2)).

When the TRA determines that the proposed remedy does meet the EIT, it must explain in the Statement of Essential Facts and the final determination why it is satisfied that the remedy is in the economic interest of the United Kingdom, with reference to the five mandatory factors and any other relevant matters. The TRA's reasoning is subject to challenge on reconsideration and on appeal to the Upper Tribunal; a determination that fails to address the statutory factors or that is based on demonstrably erroneous facts may be set aside as irrational or as an error of law.

## Secretary of State review and the public-interest override

Once the TRA has made its recommendation and its EIT determination, the Secretary of State reviews both. Schedule 4 paragraph 15(3) (for dumping and subsidy cases) and Schedule 5 paragraph 12(3) (for safeguards) provide that the Secretary of State must accept the TRA's determination that a remedy meets (or does not meet) the economic interest test unless the Secretary of State is satisfied that the determination is not one that the TRA could reasonably have made. This is a rationality standard similar to judicial review: the Secretary of State may reject the TRA's EIT determination only if it is unreasonable in the Wednesbury sense — outside the range of conclusions that a reasonable decision-maker, properly directing itself on the law and the evidence, could reach.

If the Secretary of State accepts the TRA's recommendation and is satisfied that the EIT is met, the Secretary of State publishes a notice imposing the remedy. If the Secretary of State rejects the TRA's recommendation — either because the Secretary of State considers the EIT is not met (disagreeing with the TRA's determination on rationality grounds) or because the Secretary of State concludes on wider public-interest grounds that the remedy should not be imposed — the Secretary of State must lay a statement before the House of Commons setting out the reasons for the rejection (Schedule 4 paragraph 20(4)(c); Schedule 5 paragraph 16(4)(c)). This parliamentary-reporting requirement is intended to ensure transparency and political accountability for decisions to reject trade-remedy recommendations.

## Comparison with the EU Union-interest test

The UK economic interest test is conceptually similar to the Union interest test formerly applicable to the UK when it was an EU Member State and still applicable in the EU under Article 21 of the EU Anti-Dumping Regulation (Regulation (EU) 2016/1036) and the corresponding provisions of the Anti-Subsidy Regulation. However, there are three key differences:

1. Mandatory vs discretionary. The UK EIT is mandatory in every dumping and subsidy investigation that reaches an affirmative determination; the EU test is discretionary — the European Commission may conduct a Union-interest assessment if requested by a Member State or an interested party, but is not required to do so in every case.

1. Presumption. The UK test includes a statutory presumption that the test is met (for dumping and subsidy cases) unless proved otherwise; the EU test has no formal presumption, though in practice the Commission rarely refuses to impose duties on Union-interest grounds.

1. Transparency and structure. The UK statutory framework explicitly lists the five mandatory factors and requires the TRA to publish its EIT findings in the Statement of Essential Facts and the final determination. The EU framework is less prescriptive, and Union-interest analysis is often integrated into the final Commission regulation with less granular disclosure of the evidence and reasoning.

## Practical implications for parties

For UK producers filing an application, the economic interest test creates an additional evidentiary burden beyond the traditional dumping/injury/causation determination. Applicants should anticipate that importers and downstream users will submit evidence on price increases, supply-chain disruption, and negative competitive effects, and should be prepared to rebut those claims with data showing that alternative sources of supply exist, that the price impact of a duty will be modest, and that the long-term benefits of maintaining a viable UK industry (supply-chain resilience, competition, security of supply) outweigh short-term cost increases.

For importers and downstream users, the EIT is the primary mechanism to oppose a remedy even after dumping and injury have been established. Effective participation requires early registration, completion of the TRA's business surveys, and submission of detailed economic evidence during the EIT consultation phase (typically after the provisional determination and before or during the Statement of Essential Facts comment period). Evidence should quantify cost increases, document the absence of substitute suppliers, identify any regional or sectoral concentration of harm, and — where applicable — demonstrate that the remedy would harm UK exporters' competitiveness in third-country markets.

For overseas exporters, the EIT can be a double-edged sword. If the exporter can demonstrate that imposition of a duty would lead to market exit and thereby reduce competition to the detriment of UK consumers and users, the TRA may find that the EIT is not met. Conversely, in some cases an exporter may prefer a definitive duty to the uncertainty of an expiry review or the risk of a higher injury-margin duty; undertakings (price or volume commitments) may be easier to negotiate when the TRA's preliminary EIT assessment suggests that a duty would have significant negative downstream effects.
