ICPA distinguishes controlling law, official government positions, stakeholder recommendations, media reporting, and ICPA analysis throughout this page. Negotiations do not alter an importer’s legal obligations unless implemented through an applicable legal mechanism.
No change to the current USMCA Rules of Origin has been identified as legally effective as of July 19, 2026. Current obligations remain governed by USMCA Chapter 4, Annex 4-B, the trilateral Uniform Regulations, and each country’s domestic implementing law unless and until a legally effective change is adopted.
Everything a compliance professional needs before the details.
Rules of origin determine preferential tariff eligibility, product qualification, certification obligations, supplier documentation, bill-of-material data, and verification exposure. Any change here reaches directly into sourcing decisions and customs duty liability — independent of what happens with tariffs elsewhere in the agreement.
The U.S. declined to renew USMCA in its current form on July 1, 2026, triggering annual reviews through 2036. The U.S. and Mexico have held negotiating rounds addressing automotive rules of origin, steel and aluminum, and economic security. A USMCA Chapter 31 panel has already ruled in favor of Canada and Mexico’s interpretation of the automotive core-parts “roll-up” calculation. The USITC has instituted its 2027 automotive-rules investigation, with a public hearing scheduled for October 14, 2026.
Secondary reporting has surfaced possible U.S. proposals to raise automotive regional value content and introduce a U.S.-specific content threshold. ICPA has not located these figures in published government text and has moved them to the Reported Proposals table below rather than presenting them as settled.
Potential areas of change include automotive RVC thresholds, treatment of non-market or Chinese-linked inputs, steel and aluminum origin rules, EV battery and critical-mineral rules, verification and supplier-disclosure requirements, and product-specific rules for a broader set of industrial goods. None of these have been adopted as legally effective changes.
Confirm HTS classifications, map applicable Annex 4-B rules, and identify products with narrow qualification margins or high-risk non-originating inputs.
Do not revise origin certifications, ERP calculation logic, RVC methodology, or supplier contract terms based on reported figures alone.
Rules of origin determine whether a product qualifies as originating in the United States, Mexico, or Canada and may receive preferential tariff treatment under USMCA. The governing framework includes Chapter 4, the product-specific rules in Annex 4-B, specialized automotive provisions, Chapter 5 origin procedures, textile and apparel rules under Chapter 6, trilateral Uniform Regulations, and each country’s domestic customs laws and guidance.
Rules of origin are a central issue in the continuing 2026 review. Official statements confirm negotiations concerning automotive content, rules for certain industrial goods, steel and aluminum, economic security, and the extent to which the agreement’s benefits accrue to the three parties rather than non-parties. No published agreement amending the current Rules of Origin has been located as of July 19, 2026.
For compliance teams, the immediate legal requirements remain unchanged unless and until the parties adopt a legally effective amendment, decision, regulation, or other implementing measure. Potential changes could nevertheless affect product qualification, regional-value-content calculations, supplier documentation, bills of material, certification practices, sourcing decisions, and verification exposure.

The most consequential comparisons on this page. Nothing here is legally effective unless labeled “confirmed by controlling authority.”
75% RVC for passenger vehicles, light trucks, and core parts, per the Appendix to Annex 4-B.
Increase to as high as 82%, alongside a new U.S.-specific content requirement near 50% that would exclude Canadian content. Not located in published government text.
A USMCA Chapter 31 panel confirmed the more flexible calculation method advocated by Canada and Mexico, rejecting the U.S.’s narrower tracing interpretation.
Codification of the panel’s interpretation, or a treaty-text revision adopting a stricter calculation with added tracing requirements.
Vehicle producers must purchase at least 70% of steel and 70% of aluminum from North American sources. A steel melted-and-poured requirement phases in seven years after entry into force.
Likely modification target given the U.S. has expressly paired rules-of-origin discussions with steel, aluminum, and economic-security concerns. No specific proposed text located.
Resolved litigation that remains highly relevant to how the review may unfold.
Canada and Mexico v. United States
Automotive core-parts RVC calculation, Appendix to Annex 4-B
Canada and Mexico challenged the United States’ interpretation of the core-parts rule — specifically, whether a producer that satisfied the core-parts requirement using the agreement’s permitted calculation methods could treat the resulting amount as fully originating (“roll-up”) when calculating a vehicle’s overall regional value content. The United States applied a narrower interpretation requiring additional tracing of non-originating content.
Canada and Mexico requested the panel in January 2022. In December 2022, a USMCA Chapter 31 panel ruled against the United States, confirming the more flexible “roll-up” calculation method advocated by Canada and Mexico. USTR disagreed with the ruling; USMCA does not provide a mechanism to appeal panel decisions. Confirmed
USTR’s July 2024 biennial report to Congress stated the three countries were working toward a potential resolution. ICPA has not located a published implementation agreement as of July 19, 2026.
Possible review outcomes range from codifying the panel’s interpretation to revising treaty language toward a stricter calculation, adding tracing or documentation requirements, or creating special rules for batteries, electric motors, and other advanced components.
Mexico’s economy secretary has publicly identified both the evolution of the rules and the manner in which compliance is verified as unresolved review issues — a separate policy track from the substantive percentage requirements.

Formal positions inferred only from official statements, not from press reporting or meeting attendance alone.
Seeks stronger rules of origin for automotive and key industrial goods, reduced dependence on non-party imports, tighter treatment of non-market inputs, and stronger supply-chain security. Declined to renew USMCA in its current form on July 1, 2026.
Supports continuing and extending USMCA — reportedly for another 16-year term — while acknowledging that automotive rules, evolving origin requirements, verification, steel, aluminum, and economic security remain active negotiating subjects.
Emphasizes stability, predictability, and preserving the integrated North American market. Has consistently described the review as a process for assessing and improving the agreement, not a wholesale reopening.

Source: USITC 2025 report. All 22 identified U.S. motor-vehicle producers completed the mandatory questionnaire — a 100% response rate. Effect on overall U.S. GDP and aggregate employment was estimated at less than 0.01%. Results reflect a distributional effect: higher regional sourcing can benefit parts and materials producers while increasing vehicle-production costs.
