USMCA origin framework and implementing authority
The Tratado entre México, Estados Unidos y Canadá (T-MEC, known as USMCA in the United States and CUSMA in Canada) is Mexico's predominant trade agreement by volume and governs preferential tariff treatment for goods originating in North America. The T-MEC entered into force on July 1, 2020, replacing the North American Free Trade Agreement (NAFTA). The treaty text was published in Mexico's Diario Oficial de la Federación (DOF) on June 29, 2020.
Origin criteria under Chapter 4. A good qualifies as originating—and thereby eligible for preferential tariff treatment—if it meets one of the criteria set out in T-MEC Article 4.2:
- Wholly obtained or produced entirely in the territory of one or more Parties under Article 4.3 (e.g., minerals extracted, live animals born and raised, harvested plants);
- Produced exclusively from originating materials from one or more Parties; or
- Produced in the territory of one or more Parties using non-originating materials that satisfy the applicable product-specific rule of origin (PSRO) listed in Annex 4-B, which may require a tariff-shift, a regional value content (RVC) threshold, or both, and may specify prohibited non-originating inputs for certain goods.
RVC is calculated under one of three methods specified in Article 4.5: the net-cost method (required for automotive goods under Chapter 4 Appendix and certain other goods), the transaction-value method, or the build-down method. Automotive goods face the most demanding origin requirements in the agreement: passenger vehicles and light trucks must achieve 75% RVC (phased in), and a new Labor Value Content (LVC) requirement mandates that 40–45% of vehicle production (by value) be performed by workers earning at least USD 16 per hour.
Administering authority and Uniform Regulations. In Mexico, the Secretaría de Economía (SE) is responsible for trade-policy implementation, and the Servicio de Administración Tributaria (SAT)—specifically its customs authority (autoridad aduanera)—enforces origin requirements at import. On June 30, 2020, SE published in the DOF a Resolución que establece las Reglas de Carácter General relativas a la aplicación de las disposiciones en materia aduanera del T-MEC y sus anexos (General Rules Resolution), which sets out the customs procedures for claiming preferential treatment, certification-of-origin formats, and verification protocols.
Article 5.16 of the T-MEC required the three Parties to adopt Uniform Regulations for interpreting and administering Chapters 4 (Rules of Origin), 5 (Origin Procedures), 6 (Textiles and Apparel), and 7 (Customs Administration and Trade Facilitation). The Free Trade Commission adopted Decision No. 1 on the Uniform Regulations on June 1, 2020, and an updated Decision No. 2 on May 18, 2021. Mexico published the updated Uniform Regulations in the DOF on August 13, 2021. These Uniform Regulations define critical terms—e.g., "net cost," "transaction value," "applicable change in tariff classification"—and provide detailed calculation methods and tolerances (such as the de minimis rule at Article 4.7, allowing up to 10% non-originating content by weight or value for most goods, and a tighter 7% de minimis for certain textile and apparel items).
Entry into force and sunset review. The T-MEC has a 16-year initial term from July 1, 2020. Article 34.7 mandates a joint review by the three Parties on July 1, 2026 (six years after entry into force), at which each Party must confirm in writing—at the level of head of state or government—its intent to extend the agreement for another 16-year term. If any Party declines, the agreement will be reviewed annually for the following 10 years, and any Party may withdraw on six months' notice under Article 34.6.
Mexico's FTA network — 14 agreements covering 52 countries
Mexico operates one of the world's most extensive preferential-trade networks. According to the Secretaría de Economía (SE), Mexico has 14 free trade agreements covering 52 countries, plus 30 bilateral investment treaties (Acuerdos para la Promoción y Protección Recíproca de las Inversiones, APPRIs) and 9 limited-scope trade agreements (Economic Complementation Agreements and Partial Scope Agreements) within the Latin American Integration Association (ALADI) framework. The SE maintains the authoritative registry of trade agreements under its Sistema de Información de Tratados Comerciales Internacionales (SICAIT), as required by Article 29, Section VI of the SE's Internal Regulations published in the Diario Oficial de la Federación on November 22, 2012.
Geographic distribution and major agreements
Beyond the USMCA (T-MEC, in force July 1, 2020), Mexico's FTA portfolio includes agreements across the Americas, Europe, and Asia-Pacific:
Latin America: FTAs with Chile, Costa Rica, Bolivia, Nicaragua, the Northern Triangle (El Salvador, Guatemala, Honduras), Uruguay, Colombia, Peru, and Panama. Mexico is also a founding member of the Pacific Alliance (Alianza del Pacífico), a regional-integration platform among Mexico, Chile, Colombia, and Peru that seeks liberalization of goods, services, capital, and persons and coordinates joint trade promotion. The Pacific Alliance accounts for approximately 43% of Latin America's GDP.
Europe: FTAs with the European Union (27 member states; decision of the EU–Mexico Joint Council effective July 1, 2000, modernized under a Global Agreement in 2020) and the European Free Trade Association (EFTA: Iceland, Liechtenstein, Norway, Switzerland; effective July 1, 2001). The EFTA agreement was negotiated on the basis of the EU FTA template.
Middle East: FTA with Israel (effective July 1, 2000).
Asia-Pacific: The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP, known in Mexico as Tratado Integral y Progresista de Asociación Transpacífico or TIPAT). The CPTPP was signed by Mexico on March 8, 2018, in Santiago, Chile, approved by the Mexican Senate on April 24, 2018, and entered into force for Mexico on December 30, 2018. The agreement has 11 member states: Australia, Brunei Darussalam, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, and Vietnam. For Mexico, the CPTPP provides FTA access to six Asia-Pacific economies with which it did not previously have comprehensive FTAs: Australia, Brunei, Malaysia, New Zealand, Singapore, and Vietnam.
ALADI Economic Complementation Agreements and Partial Scope Agreements
In addition to comprehensive FTAs, Mexico has signed 9 limited-scope agreements under the ALADI framework, which was established by the 1980 Montevideo Treaty. These Economic Complementation Agreements (ACEs) and Partial Scope Agreements cover specific sectors or product lines and typically do not include the full trade disciplines (services, intellectual property, government procurement, investment) found in comprehensive FTAs. Examples include ACE 6 (Argentina), ACE 53 (Brazil), and ACE 55 (Mercosur).
CPTPP as a "next-generation" agreement
The CPTPP is described by SE as part of a long-term strategy to complement USMCA and reinforce the Pacific Alliance. The agreement includes commitments on digital trade, state-owned enterprises, regulatory coherence, intellectual property, labor, environment, and services that go beyond traditional WTO disciplines. Several provisions in the USMCA were drawn from the original Trans-Pacific Partnership (TPP) negotiating text.
Rules of origin and certification framework
Each FTA has its own product-specific rules of origin (PSROs) set out in annexes to the treaty. The general origin framework follows the pattern established in NAFTA and USMCA: goods qualify as originating if they are (i) wholly obtained in the territory of one or more parties, (ii) produced exclusively from originating materials, or (iii) satisfy the applicable tariff-shift requirement and/or regional-value-content threshold specified for the relevant tariff heading. De minimis tolerances, accumulation rules, and certification-of-origin formats vary by agreement.
Under USMCA and CPTPP, origin certification is by self-certification (the exporter, producer, or importer may certify origin). Under older agreements such as the EU and EFTA FTAs, origin is certified by an authorized issuer (typically a chamber of commerce or government authority in the exporting country).
The Servicio de Administración Tributaria (SAT)—Mexico's customs and tax authority—enforces origin requirements at import. The Secretaría de Economía issues implementing regulations for each FTA, published in the Diario Oficial de la Federación.
Multilateral participation
Mexico is also a member of the World Trade Organization (WTO; member since 1986 under GATT, founding WTO member in 1995), the Asia-Pacific Economic Cooperation (APEC) forum, and the Organisation for Economic Co-operation and Development (OECD).

USMCA certification of origin — self-certification format and data requirements
Under the USMCA (T-MEC), certification of origin is based on a self-certification system that eliminates the requirement for third-party validation by chambers of commerce or government agencies. Article 5.2 of the T-MEC permits any of three parties—the exporter, the producer, or the importer—to certify that a good qualifies as originating and is therefore eligible for preferential tariff treatment. This represents a significant departure from the NAFTA system, which required the exporter or producer to complete the certificate, and from many of Mexico's older FTAs (such as those with the EU and EFTA), which still mandate official certificates issued by authorized bodies.
Who may certify origin
USMCA Article 5.2 provides that a certification of origin may be completed and signed by the exporter of a good, the producer of a good, or the importer of record. When the exporter is not the producer, the exporter must obtain from the producer a certification or other written statement demonstrating that the good qualifies as originating. The importer may likewise certify origin based on knowledge that the good qualifies, including knowledge based on a written statement or certification from the producer or exporter.
The Resolución que establece las reglas de carácter general relativas a la aplicación de las disposiciones en materia aduanera del T-MEC (the T-MEC Resolution), published by the Secretaría de Economía in the Diario Oficial de la Federación on June 30, 2020, sets out the implementing procedures for Mexico. Rules 12 and 13 of the T-MEC Resolution specify that an importer claiming preferential treatment must possess a valid certification of origin at the time the claim is made (not necessarily at the time of importation, but the importer must be able to provide it promptly if requested by Mexican customs). The certification may be in the format set out in Annex 5-A of the T-MEC or in any format that includes the minimum data elements specified in Article 5.2.
Minimum data elements
Article 5.2 of the T-MEC and the Uniform Regulations (adopted by Free Trade Commission Decision No. 2 on May 18, 2021, and published in Mexico's DOF on August 13, 2021) identify nine minimum data elements that must appear in a certification of origin:
- Certifier — indicate whether the certifier is the exporter, producer, or importer, and provide the certifier's name, title (if applicable), address (including country), telephone, and e-mail.
- Exporter — name and address (including country); if not the certifier, may state "various" if multiple exporters are covered by a blanket certification.
- Producer — name and address (including country); if confidential or if there are multiple producers, may state "available to customs upon request."
- Importer — name and address (if known); may state "unknown" or "various."
- Description and HS tariff classification — sufficient detail to relate the certification to the invoice and the good, and the six-digit HS subheading (or eight-digit national tariff line if required by a product-specific rule of origin).
- Origin criterion — indicate which basis under Article 4.2 the good qualifies: (A) wholly obtained, (B) produced exclusively from originating materials, (C) satisfies the product-specific rule in Annex 4-B using the applicable tariff shift or regional value content, or (D) under an alternative staging category for automotive goods or other sector-specific rules.
- Blanket period — if the certification covers multiple shipments of identical goods for a specified period (up to 12 months), state the "from" and "to" dates (format: YYYY-MM-DD).
- Authorized signature and date — the certifier's signature (or digital equivalent under the importing Party's law) and the date of signing (format: YYYY-MM-DD).
- Certification text — a statement, in English, Spanish, or French, that the good qualifies as originating under the USMCA. The Uniform Regulations provide template text in each language; for a certification in Spanish, the statement is: "Certifico que los bienes descritos en este documento califican como originarios y que la información contenida en este documento es verdadera y exacta. Asumo la responsabilidad de comprobar lo aquí declarado y de mantener y presentar la documentación necesaria que respalde esta certificación, así como de informar, de conformidad con el Artículo 5.10, a todas las personas a quienes se les haya entregado esta certificación, de cualquier cambio que pudiera afectar la exactitud o validez de la misma. La presente certificación consta de [indicar el número total] páginas, incluyendo todos sus anexos."
Format flexibility and electronic transmission
Article 5.2 expressly permits the certification to be prepared in any format, provided it contains the minimum data elements. In practice, most traders use the template in Annex 5-A of the T-MEC, which is a fillable table. The certification may be transmitted electronically and need not be a stand-alone document; it may appear on an invoice, a bill of lading, a packing list, or any other commercial document. Under Article 5.7, each Party must accept a certification transmitted electronically.
Validity and record-keeping
A certification of origin is valid for one year from the date of signing (T-MEC Article 5.4), or for the period stated in a blanket certification (up to 12 months from the blanket-period start date). The certifier must retain records supporting the origin determination for five years from the date of signing (Article 5.9), and Mexico's SAT may verify origin during this window under the procedures in Chapter 6 of the T-MEC and Chapter 6.3 of Mexico's Reglas Generales de Comercio Exterior (RGCE).
The importer claiming preferential treatment in Mexico must file the customs declaration (pedimento) with the appropriate tariff preference identifier and have the certification of origin in its possession. SAT's verification authority is set out in Article 5.11 of the T-MEC and Rules 6.3.1–6.3.7 of the RGCE. If origin cannot be verified, the importer is liable for the MFN duties and any applicable penalties under Mexico's customs law (Ley Aduanera).
Correcting or replacing a certification
Article 5.10 of the T-MEC requires the certifier to promptly notify in writing all persons to whom the certification was provided if the certifier becomes aware that the certification contains incorrect or false information. The importer must then notify Mexican customs and pay any additional duties owed. A corrected certification may be provided, but it does not retroactively validate preferential treatment claimed on the basis of the incorrect certification.
USMCA regional value content — calculation methods (transaction value, net cost, and build-down)
When a product-specific rule of origin (PSRO) in Annex 4-B of the USMCA imposes a regional value content (RVC) requirement, the producer or exporter must calculate the percentage of North American content using one of the methods prescribed in Article 4.5 of the T-MEC. The three primary methods are the transaction-value method, the net-cost method, and the build-down method. Choosing the correct method—and applying it accurately—is critical to determining whether a good qualifies as originating and may claim preferential tariff treatment when imported into Mexico, the United States, or Canada.
General RVC thresholds
Most non-automotive goods subject to an RVC requirement under the USMCA must achieve 60% RVC if the transaction-value method is used, or 50% RVC if the net-cost method is used. These thresholds are specified in Article 4.5(2) and (3) of the T-MEC. Automotive goods are subject to higher thresholds—75% RVC for passenger vehicles and light trucks (phased in as of July 1, 2023), and 70% RVC for heavy trucks—and the net-cost method is mandatory for automotive goods under the Automotive Appendix to Annex 4-B.
Transaction-value method (Article 4.5(2))
The transaction-value method measures RVC by comparing the adjusted value of the good (its sales price, less certain costs) to the value of non-originating materials. The formula is:
RVC = [(TV − VNM) / TV] × 100
where:
- TV (transaction value of the good) is the price actually paid or payable for the good when sold for export to the territory of a USMCA Party, adjusted in accordance with the principles of Articles 8(1), 8(3), and 8(4) of the WTO Customs Valuation Agreement, and excluding the international-freight, insurance, and packing costs incurred in shipping the good from the territory of exportation to the territory of importation. TV is the ex-works or FOB value—what the buyer pays at the point of export.
- VNM (value of non-originating materials) is the sum of the transaction values of all materials used in the production of the good that do not qualify as originating under Chapter 4. The transaction value of a material is determined under Articles 1 through 8 of the Customs Valuation Agreement and is adjusted to an FOB, CIF, or other basis as defined in the Uniform Regulations. Importantly, Article 4.5(4) of the T-MEC provides that the value of non-originating materials used to produce an originating material is not counted again when that originating material is subsequently used in the production of the finished good. This is the "roll-up" or cumulation principle: once a material qualifies as originating by meeting its own PSRO, it is treated as having zero non-originating content when incorporated into the next stage of production.
The transaction-value method is the default and is simpler to administer when the producer sells the good at arm's length. It requires accurate records of material purchase prices and the ability to segregate originating from non-originating materials.
Net-cost method (Article 4.5(3))
The net-cost method measures RVC by reference to the net cost of producing the good, which is defined in the Uniform Regulations as total cost minus sales promotion, marketing, after-sales service, royalties, shipping and packing, and non-allowable interest costs. The formula is:
RVC = [(NC − VNM) / NC] × 100
where:
- NC (net cost) is calculated under the Uniform Regulations Section 7 (Net Cost Method). It is derived from the producer's books and records kept in accordance with Generally Accepted Accounting Principles (GAAP) applicable in the territory of the Party where the good is produced. Net cost includes product costs (materials, direct labor, direct overhead) and certain period costs allocable to the good, but excludes the enumerated costs (sales promotion, marketing, after-sales service, royalties, shipping, packing, and non-allowable interest).
- VNM is determined as in the transaction-value method, with the same roll-up rule under Article 4.5(4).
The net-cost method is mandatory when:
- The PSRO in Annex 4-B specifies that only the net-cost method may be used (as is the case for all automotive goods under the Automotive Appendix);
- The good is sold between related parties and the transaction value is not acceptable for RVC purposes under the principles of the Customs Valuation Agreement;
- During a verification proceeding under Chapter 5, the importing Party's customs authority notifies the producer or exporter that the transaction value is unacceptable or must be adjusted.
If the net-cost method is not mandatory, the producer may elect to use it as an alternative to the transaction-value method, but once a particular method is used for a certification of origin, that choice governs for the period covered by the certification.
Build-down method (alternative transaction-value formula)
Some older NAFTA-legacy PSROs and non-USMCA FTAs (such as the U.S.–Chile FTA) permit a build-down formula as an alternative to the transaction-value formula. Under the USMCA, the build-down approach is functionally equivalent to the transaction-value method but expressed in a different order:
RVC = [(TV − VNM) / TV] × 100
This is mathematically identical to the transaction-value formula in Article 4.5(2). The term "build-down" reflects the calculation starting from the adjusted value (TV) and subtracting the value of non-originating materials. The USMCA text does not use the term "build-down," but the Uniform Regulations and implementing guidance from the Secretaría de Economía recognize that the formula in Article 4.5(2) serves the same function.
Intermediate materials and self-produced materials (Article 4.6)
Article 4.6 of the T-MEC permits a producer to designate a self-produced material as an intermediate material for the purpose of calculating RVC. When a self-produced material is designated as intermediate, the RVC of that material is calculated separately, and if it qualifies as originating, it may be valued at its total cost for purposes of calculating the RVC of the finished good. This allows the producer to capture the value-added at each stage of production and can simplify RVC calculations for complex goods. However, only one level of intermediate-material designation is permitted: if the intermediate material itself is subject to an RVC requirement, no material used to produce the intermediate material may itself be designated as intermediate.
De minimis tolerance (Article 4.7)
Even when a good uses non-originating materials that do not undergo the tariff shift required by the PSRO, the good may still qualify as originating if the value (or weight) of all such non-originating materials does not exceed 10% of the transaction value (or total weight) of the good. This de minimis rule is subject to product-specific exceptions: for certain textile and apparel goods, the threshold is 7% by weight, and some automotive goods and other sensitive products are excluded entirely from the de minimis rule.
Record-keeping and verification
Under Article 5.9 of the T-MEC and the implementing regulations published by SAT, the producer or exporter must maintain complete records supporting the RVC calculation—including material purchase invoices, supplier certifications, production records, and accounting ledgers showing total cost and net cost—for five years from the date the certification of origin is signed. Mexican customs (SAT) may verify the RVC calculation during this period under the procedures in Chapter 5 and Chapter 6.3 of Mexico's Reglas Generales de Comercio Exterior.
Automotive-specific requirements
For passenger vehicles, light trucks, and heavy trucks, the Automotive Appendix to Annex 4-B mandates the net-cost method and imposes additional requirements: separate RVC calculations for specified "core parts" (engines, transmissions, bodies, axles, suspension systems, steering systems, and advanced batteries), a requirement that 70% of steel and aluminum purchases be melted and poured in North America, and a Labor Value Content (LVC) requirement that 40–45% of the vehicle's production value be performed by workers earning at least USD 16 per hour. The detailed LVC calculation methodology is set out in Article 7 of the Automotive Appendix and Section 8 of the Uniform Regulations.
Uniform Regulations and implementing guidance
The Uniform Regulations (Reglamentaciones Uniformes) adopted by the USMCA Free Trade Commission on May 18, 2021, and published in Mexico's Diario Oficial de la Federación on August 13, 2021, provide the authoritative definitions and computational rules for transaction value, net cost, VNM, and all related terms. Sections 6 and 7 of the Uniform Regulations specify how to determine total cost, net cost, and the treatment of overhead, royalties, and other costs under GAAP. The Secretaría de Economía's Resolución que establece las Reglas de Carácter General relativas a la aplicación de las disposiciones en materia aduanera del T-MEC (DOF, June 30, 2020) sets out the procedural framework for claiming RVC-based preferential treatment when importing into Mexico, including the documentation that SAT may request during verification.
CPTPP origin rules and certification — regional value content thresholds, de minimis, and self-certification procedures
The Tratado Integral y Progresista de Asociación Transpacífico (TIPAT, known internationally as the Comprehensive and Progressive Agreement for Trans-Pacific Partnership, or CPTPP) entered into force for Mexico on December 30, 2018. The treaty was promulgated in Mexico's Diario Oficial de la Federación on November 29, 2018, and establishes preferential origin rules and self-certification procedures that differ materially from those in the USMCA. For Mexican exporters and importers trading with the ten other CPTPP Parties—Australia, Brunei, Canada, Chile, Japan, Malaysia, New Zealand, Peru, Singapore, and Vietnam—the CPTPP origin framework governs eligibility for preferential tariff treatment.
Origin criteria (CPTPP Article 3.2)
A good qualifies as originating under the CPTPP if it meets one of the following criteria set out in Article 3.2:
- Wholly obtained or produced entirely in the territory of one or more CPTPP Parties under Article 3.3 (e.g., minerals extracted, live animals born and raised, harvested plants, fish caught in the territorial sea or exclusive economic zone);
- Produced exclusively from originating materials from one or more CPTPP Parties; or
- Produced in the territory of one or more Parties using non-originating materials that satisfy the applicable product-specific rule of origin (PSRO) in Annex 3-D, which may require a tariff shift, a regional value content (RVC) threshold, or both, and may prohibit certain non-originating inputs.
These three criteria are parallel to the USMCA structure. However, the product-specific rules in CPTPP Annex 3-D differ from those in USMCA Annex 4-B. A good that qualifies for preferential treatment under USMCA may not qualify under CPTPP for the same destination market (notably Canada), and vice versa, because the tariff-shift requirements, RVC thresholds, and prohibited-materials lists are negotiated separately for each FTA.
Regional value content (RVC) calculation methods and thresholds (Article 3.5)
When a PSRO in Annex 3-D requires regional value content, the producer or exporter must calculate RVC using one of two methods specified in Article 3.5:
- Transaction-value method (focused-value method):
RVC = [(AV − VNM) / AV] × 100 where AV (adjusted value) is the value of the good adjusted to an FOB, FCA, or ex-works basis (excluding international freight, insurance, and packing), and VNM is the value of non-originating materials. For most goods, the RVC threshold under this method is 55% (compared to 60% under USMCA).
- Build-up method:
RVC = (VOM / AV) × 100 where VOM (value of originating materials) is the sum of the value of materials originating in one or more CPTPP Parties, plus the direct labor cost and direct overhead incurred in the production of the good, plus other costs and profit. For most goods, the RVC threshold under this method is 45% (compared to 50% net-cost RVC under USMCA).
The CPTPP does not have a net-cost method equivalent to USMCA Article 4.5(3). Instead, the build-up method allows the producer to count originating materials, direct labor, direct overhead, and other value-added in the territory of one or more CPTPP Parties. Accumulation is permitted: materials originating in any CPTPP Party count as originating when incorporated into a good produced in another CPTPP Party (Article 3.8).
De minimis tolerance (Article 3.11)
A good that uses non-originating materials that do not undergo the tariff shift required by the applicable PSRO may still qualify as originating if the value of all such non-originating materials does not exceed 10% of the value (or weight) of the good. This de minimis rule is subject to exceptions listed in Annex 3-C; certain textile and apparel goods (Chapter 4 of the CPTPP) are subject to a lower threshold (7% by weight for specific categories), and certain dairy, sugar, and other sensitive products are excluded entirely from the de minimis rule.
The CPTPP de minimis list in Annex 3-C differs from USMCA Article 4.7's exceptions. A compliance officer applying both agreements to the same supply chain must check each treaty's Annex independently.
Self-certification procedures (Article 3.20 and Annex 3-B)
The CPTPP uses a self-certification system similar to the USMCA. Under Article 3.20, a certification of origin may be completed by the exporter or the producer. Importer certification is also permitted, but Mexico elected a five-year transition period from the date of entry into force before accepting importer certifications. Since the CPTPP entered into force for Mexico on December 30, 2018, importer certification for goods imported into Mexico became available on December 30, 2023. During the transition period (December 30, 2018, through December 29, 2023), only exporter or producer certifications were accepted by Mexican customs (SAT).
Minimum data requirements (Annex 3-B) for a CPTPP certification of origin are set out in Annex 3-B and parallel the USMCA framework with minor differences. The certification must include:
- Certifier — indicate whether the certifier is the exporter, producer, or importer (if permitted by the importing Party), and provide the certifier's name, address, telephone, and e-mail.
- Exporter — name and address (including country).
- Producer — name and address (if known); may state "available upon request" if confidential or if multiple producers are covered.
- Importer — name and address (if known); may state "unknown" or "various."
- Description and HS tariff classification — sufficient detail to relate the certification to the invoice and the good, and the six-digit HS subheading.
- Origin criterion — indicate which basis under Article 3.2 the good qualifies: (A) wholly obtained, (B) produced exclusively from originating materials, (C) satisfies the product-specific rule in Annex 3-D, or (D) other (specify).
- Blanket period — if the certification covers multiple shipments of identical goods for a specified period (up to 12 months), state the "from" and "to" dates.
- Authorized signature and date — the certifier's signature and the date of signing.
There is no prescribed format. The certification may be on an invoice, a bill of lading, a packing list, or any other commercial document, provided it contains the minimum data elements. It may be transmitted electronically.
Validity and record-keeping (Articles 3.22 and 3.24)
A certification of origin is valid for one year from the date of signing (or for the period stated in a blanket certification, up to 12 months). The certifier must retain all records supporting the origin determination—including material purchase invoices, production records, and accounting ledgers—for at least three years from the date of signing (Article 3.24). This is a shorter retention period than the five years required under USMCA Article 5.9; compliance programs must track both obligations when certifying under multiple agreements.
Verification and compliance
The importing Party's customs authority may verify origin during the three-year retention period under the procedures in Article 3.27. For imports into Mexico, the Servicio de Administración Tributaria (SAT) may request records from the certifier, conduct questionnaires, or (with the consent of the exporting Party) visit the producer's facility. If origin cannot be verified, the importer is liable for the most-favored-nation (MFN) duties and any applicable penalties under Mexico's Ley Aduanera.
The Secretaría de Economía has published implementing guidance for CPTPP certification in the Diario Oficial de la Federación and on its trade-agreements portal (gob.mx/se). Importers claiming CPTPP preferential treatment must file the customs declaration (pedimento) with the appropriate tariff-preference identifier and have the certification of origin in their possession (or be able to provide it promptly upon SAT's request).
Comparison with USMCA for trade-compliance planning
For goods moving between Mexico and Canada (both USMCA and CPTPP Parties), or between Mexico and other dual-FTA partners (Chile, Peru), the compliance officer must evaluate which agreement offers the more favorable treatment. Key variables include:
- RVC thresholds: CPTPP is 55% (transaction-value) or 45% (build-up) for most goods; USMCA is 60% (transaction-value) or 50% (net-cost). If a good has high North American content but sources key inputs from Asia, CPTPP may be preferable because accumulation across 11 Asia-Pacific economies is permitted.
- Product-specific rules: The tariff-shift or RVC requirement for a given HS heading may differ. For example, certain steel products under HS Chapter 72 have a more permissive PSRO under CPTPP than under USMCA.
- Automotive goods: USMCA has strict automotive origin rules (75% RVC, Labor Value Content, steel-and-aluminum melted-and-poured requirements) that do not appear in CPTPP. Finished vehicles and automotive parts destined for the U.S. or Canadian markets will typically not qualify under CPTPP's general RVC thresholds but may qualify under USMCA if they meet the higher thresholds.
- De minimis and other tolerances: CPTPP Annex 3-C excludes certain products (notably dairy) that are not excluded under USMCA Article 4.7, and vice versa.
Mexican exporters should maintain dual origin analysis worksheets and certifications when selling into CPTPP markets that are also USMCA Parties, and claim preferential treatment under the agreement that yields the lowest duty.
