USMCA Rules of Origin: How to Qualify Goods for Duty-Free Trade
What Is USMCA?
The United States-Mexico-Canada Agreement (USMCA) is the free trade agreement among the three North American countries that entered into force on July 1, 2020, replacing the North American Free Trade Agreement (NAFTA). USMCA was implemented in the United States by the USMCA Implementation Act (Public Law 116-113) and is administered by USTR, CBP, and the Department of Commerce.
USMCA preserves the duty-free treatment for qualifying goods that previously moved under NAFTA, while adding new requirements for automotive content, labor, intellectual property, and digital trade. The agreement is subject to a joint review every six years, with the first review scheduled for 2026.
Official text and uniform regulations are published at ustr.gov/trade-agreements/free-trade-agreements/united-states-mexico-canada-agreement. CBP implementing regulations appear at 19 CFR Part 182.
Why USMCA Qualification Matters in 2026
USMCA qualification has become significantly more valuable since 2025. The Trump administration imposed IEEPA tariffs on Mexico and Canada under the fentanyl and migration emergency declarations (Executive Orders 14193 and 14194 issued February 2025, modified by subsequent orders).
USMCA-qualifying goods are exempt from these IEEPA tariffs. Non-qualifying goods from Mexico and Canada pay the IEEPA rate (typically 25%) in addition to any standard MFN duty. This creates a sharp economic incentive to properly document USMCA qualification for every eligible shipment.
Many importers historically declared NAFTA or USMCA preference on a default basis without rigorous origin analysis. CBP has substantially increased verification and audit activity in 2025-2026, and incorrect USMCA claims now expose importers to both back duties and penalties under 19 U.S.C. 1592.
The Three Categories of USMCA Originating Goods
USMCA Article 4.2 defines three categories of goods that qualify as originating.
Category A: Wholly obtained or produced. Goods that are entirely produced in one or more USMCA countries from materials wholly obtained in those countries. Examples include live animals born and raised in USMCA territory, plants grown in USMCA territory, fish caught in USMCA waters, and minerals extracted from USMCA soil.
Category B: Produced from originating materials. Goods produced entirely in USMCA territory exclusively from materials that are themselves originating. This is common in continuous production chains where all inputs already qualify.
Category C: Produced using non-originating materials that meet a Product-Specific Rule of Origin. Most manufactured goods qualify under Category C. The Product-Specific Rules (PSRs) appear in USMCA Annex 4-B and prescribe a tariff shift, regional value content (RVC) requirement, or specific process for each HTS subheading.
Tariff Shift Rules
A tariff shift requires that non-originating materials be classified under a different HTS heading or subheading than the finished good. The shift demonstrates substantial transformation in USMCA territory.
Common tariff shift formulations in Annex 4-B:
Change in Chapter (CC): Non-originating materials must shift from a different Chapter (2-digit level) to the finished good’s Chapter. This is the most demanding shift requirement.
Change in Tariff Heading (CTH): Non-originating materials must shift from a different 4-digit heading. This is the most common shift requirement.
Change in Tariff Subheading (CTSH): Non-originating materials must shift from a different 6-digit subheading. This is the least demanding shift.
Some Annex 4-B rules combine a tariff shift with an RVC requirement, or offer alternative paths (tariff shift OR RVC).
Regional Value Content (RVC)
Regional Value Content measures the proportion of a good’s value that originates in USMCA territory. USMCA permits two calculation methods, with the importer or producer free to choose either method except where the PSR specifies one.
Transaction Value Method:
RVC = ((Transaction Value − Value of Non-Originating Materials) / Transaction Value) × 100
Net Cost Method:
RVC = ((Net Cost − Value of Non-Originating Materials) / Net Cost) × 100
Required RVC thresholds vary by product. General manufactured goods typically require 60% (transaction value) or 50% (net cost). Automotive products have substantially higher thresholds discussed below.
Automotive Rules of Origin
USMCA imposed strict new rules of origin for automotive goods that exceed the prior NAFTA standards. These rules are codified in USMCA Chapter 4 Appendix and were phased in through 2023, with final compliance levels now in effect.
Passenger vehicles and light trucks: 75% RVC required (up from 62.5% under NAFTA), calculated under the Net Cost Method.
Heavy trucks: 70% RVC required.
Auto parts: Three categories (Core Parts, Principal Parts, Complementary Parts) with RVC thresholds of 75%, 70%, and 65% respectively.
Steel and aluminum purchasing requirement: 70% of a vehicle producer’s steel and aluminum purchases must be of USMCA origin.
Labor Value Content (LVC): 40% of passenger vehicle content (45% for trucks) must be produced by workers earning at least $16 per hour in USMCA territory. LVC is unique to USMCA and has no NAFTA precedent.
Certification of Origin
Unlike NAFTA, USMCA does not prescribe a specific certification form. Instead, certification can be made on any document that contains the nine required data elements specified in USMCA Annex 5-A.
Required data elements:
1. Identification of the certifier (importer, exporter, or producer)
2. Certifier’s name, address, and contact information
3. Exporter’s name and address (if different from certifier)
4. Producer’s name and address (if different from certifier)
5. Importer’s name and address
6. Description and HTS classification of the good
7. Origin criterion (A, B, or C)
8. Blanket period (if applicable, up to 12 months)
9. Authorized signature, date, and certification statement
The certification can be made by the importer, exporter, or producer. The certifier must possess records supporting the origin claim and produce them upon CBP verification.
CBP Verification and Penalties
CBP enforces USMCA origin claims through written verification, on-site verification visits, and audit programs. Verification can occur up to five years after entry.
Verification methods (USMCA Article 5.9):
1. Written request to the importer for information
2. Written request to the exporter or producer in the exporting country
3. Verification visit to the exporter or producer (with consent)
4. Other procedures as agreed
Consequences of denied claims:
1. Reliquidation with assessment of MFN duty plus IEEPA tariff (currently 25% for Mexico and Canada non-USMCA goods)
2. Interest on unpaid duties from date of original entry
3. Penalties up to four times the unpaid duties for negligence (19 U.S.C. 1592)
4. Higher penalties for gross negligence or fraud
De Minimis Provisions
USMCA provides a de minimis tolerance allowing limited use of non-originating materials that fail the tariff shift rule.
General de minimis: Up to 10% of the transaction value (or 10% of net cost) of the good can consist of non-originating materials that fail the applicable tariff shift, and the good still qualifies. The 10% de minimis does not apply to certain agricultural goods or to inputs that fail an RVC requirement.
Textile de minimis: 10% by weight for the component that determines tariff classification.
Frequently Asked Questions
Does USMCA cover services?
Yes. USMCA includes chapters on cross-border trade in services, financial services, telecommunications, digital trade, and temporary entry for business persons. This article focuses only on goods.
Can I claim USMCA preference retroactively?
Yes. Under USMCA Article 5.4, importers can claim preference up to one year after importation through a post-summary correction or protest, provided supporting certification exists.
What happens during the 2026 USMCA review?
The first joint review is scheduled for July 2026. The three parties will assess compliance and decide whether to extend USMCA for another 16 years, or to enter a 10-year sunset period requiring further negotiation.
Are USMCA-originating goods exempt from Section 232 steel and aluminum tariffs?
Originally yes for Mexico and Canada. The 2025 expansion of Section 232 modified this treatment. Mexico and Canada steel and aluminum imports may face Section 232 duties depending on the current proclamation status.
Do I need an MID (Manufacturer Identification) for USMCA claims?
Yes. Manufacturer ID must be reported on entry summaries for USMCA claims, allowing CBP to identify the producer for verification purposes.
