Rules of Origin
The framework governing whether a good qualifies for USMCA’s preferential tariff treatment, and one of the most consequential, actively negotiated areas of the 2026 joint review. The USMCA origin rules themselves are unchanged, and the reported U.S. push for a country-specific automotive content threshold remains live and contested; as of October 18, 2026, ICPA has located no announced date for the fourth U.S.–Mexico round, which Secretary Ebrard said on October 16 “tiene que ser antes del fin de año.” What changed on August 22 is the value of qualifying: the new 50 percent Section 338 duties apply to covered Canadian goods whether or not they are USMCA originating.

No change to the current USMCA Rules of Origin has been identified as legally effective as of October 18, 2026. Current obligations remain governed by USMCA Chapter 4, Annex 4-B, the Appendix to Annex 4-B (automotive), the trilateral Uniform Regulations, and each country’s domestic implementing law unless and until a legally effective change is adopted. The developments below concern the negotiation environment, not the governing text.
Five-Minute Briefing
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. That value rose in late July 2026: Mexico said USMCA-compliant goods would remain exempt from the new U.S. forced-labor tariff action, with roughly 85 percent of Mexican exports staying tariff-free if they satisfy the agreement’s rules of origin.
The U.S. declined to renew USMCA in its current form on July 1, 2026, triggering annual reviews through 2036. The third U.S.–Mexico bilateral round concluded in Mexico City on July 23, 2026, with rules of origin bundled alongside steel and aluminum, automobiles, and economic security; a fourth round was then set for Washington in September 2026 and has since been reported as moved to October; ICPA has located no announced date as of October 18; on October 16 Economy Secretary Ebrard told Mexico’s Chamber of Deputies the round “tiene que ser antes del fin de año.” 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; its public hearing was scheduled for October 14, 2026, and post-hearing briefs are due October 21 and other written submissions November 2, 2026. On October 14 Commerce (BIS) published guidance to CBP, effective that day, defining “U.S. content” for the Section 232 metals deduction available to USMCA-qualifying goods under Proclamation 11032; it does not amend the USMCA rules of origin.
Reuters reported on July 24, 2026 that a central sticking point remains a U.S. demand that vehicles contain 50 percent U.S.-made content to qualify for preferential access, and that Mexico strongly opposes it. Current USMCA rules still require 75 percent North American content with no country-specific share. ICPA has not located these figures in published government text and has moved them to the Reported Proposals section 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. The July 23 official language emphasizing “free-riding from non-parties” suggests the next wave of pressure may be as much about verification architecture and tracing as about headline percentages. None of these have been adopted as legally effective changes.
Since August 22, Canadian-origin goods on the Section 338 lists pay an additional 50 percent whether or not they qualify under USMCA, and the entry must carry the right Chapter 99 heading. That is a filing change, not an origin change, and it is live today:
- Screen every Canadian-origin line against CBP’s September 15 modified Section 338 list (CSMS # 69851916) and the September 29 import-exclusion annexes, not only dairy, alcohol, and vehicles; cement (2523.29.00) and salt (2501.00.00) left the list on September 15
- File covered entries under the correct HTSUS 9903.03.12–9903.03.14 heading rather than omitting the Chapter 99 line; since September 15 the zero-rate 9903.03.15 (Section 232 goods) is available only for goods under the dairy heading 9903.03.13, and 9903.03.16 covers civil-aircraft articles
- Do not treat a valid USMCA certification as an exemption; the duty applies to originating goods
- If you export to Canada, check the published Finance Canada product list for the September 8 counter-tariffs (steel, dairy, appliances, agricultural equipment, pulp and paper, electronics) and CBSA Customs Notices 26-23 and 25-11, including any applicable remission
- Refresh BOM mapping and HTS classification for products with narrow qualification margins
- Identify products with heavy reliance on non-party inputs or significant Canadian content
- Strengthen supplier-origin support and preference-utilization analysis
- Treat Chinese-linked inputs, battery materials, and sensitive upstream sourcing as an early-warning watch
Do not rebuild origin certifications, ERP calculation logic, RVC methodology, or supplier contract terms around the reported 82 percent or 50 percent figures. The treaty baseline is unchanged; the numbers are reported, not published government text.
Confirmed Developments
Official government actions and confirmed events relevant to rules of origin. None of these amends the USMCA text.
The Department of Labor’s Wage and Hour Division published a Paperwork Reduction Act notice (91 FR 65800, FR Doc. 2026-21169) on the information collection for the high-wage components of the USMCA labor value content (LVC) requirements, OMB Control Number 1235-0032. The notice states that “the current approval for this collection will expire on January 31, 2027” and that “The Department seeks to extend PRA authorization for this information collection for 3 more years, without any change to existing requirements.” The collection covers the records vehicle producers maintain under 29 CFR 810.600 to support their high-wage LVC calculations, which “will often include worker time records, payroll records,” and which the Administrator may request to verify the high-wage components of the LVC requirements for “passenger vehicles, light trucks, and heavy trucks.” DOL estimates 9,343 respondents, 6,221,407 annual responses and 219,689 burden hours. Comments are due on or before December 15, 2026. Federal Register, 91 FR 65800, Oct 16 ↗
The Bureau of Industry and Security published guidance to CBP (91 FR 65162, FR Doc. 2026-20938, Docket No. 260918-0056) stating that, “for purposes of implementing clause (2)(d) of the Proclamation,” U.S. content means “1. The value of the product attributable to parts wholly obtained, entirely produced, or substantially transformed in the United States, and 2. To the extent not otherwise accounted for in (1), the value of the product attributable to steel that was melted and poured in the United States, aluminum that was smelted and cast in the United States, and/or copper that was smelted and cast in the United States.” The guidance is effective for goods entered, or withdrawn from warehouse, for consumption on or after 12:01 a.m. ET October 14, 2026. It sets out no filing procedure and directs product-specific questions to CBP. Under Proclamation 11032 itself (91 FR 34085), for the Annex I-C aluminum and steel articles entered June 8, 2026 through December 31, 2027, clause (2)(d) provides that for products of Canada and Mexico that qualify for USMCA preferential treatment “a duty of 25 percent shall apply only to the non-U.S. content of the product” and that “the total effective duty on the imported product assessed under this subclause shall not be less than 15 percent ad valorem.” ICPA analysis, not stated in the source: Proclamation 11032 defines non-U.S. content as total value minus “the value attributable to parts produced in the United States”; the BIS definition supplies the origin-based test (wholly obtained, entirely produced or substantially transformed) that CBP will now apply to that phrase. The notice does not reference CBP’s June 5, 2026 CSMS # 68855869, which instructs filers to report non-U.S. and U.S. content of USMCA-eligible derivative steel articles of Canada or Mexico on two lines under HTSUS 9903.82.20/9903.82.21 and to “not report more than 40 percent of the value of the U.S. content of the good in heading 9903.82.21”; we have located no CBP message updating that guidance as of October 18, 2026. USMCA qualification is the gate to the clause (2)(d) treatment, so a defensible origin claim carries Section 232 value as well as preference value; the USMCA rules of origin themselves are unchanged.

The USITC has instituted its 2027 automotive-rules-of-origin economic-impact investigation (No. 332-608, 91 FR 8521) and set its public hearing for October 14, 2026. Under the Commission’s corrected schedule (FR Doc. 2026-03841, 91 FR 9640), posthearing briefs and statements are due October 21, 2026 and all other written submissions and summaries of views are due November 2, 2026. This is the statutory economic-analysis track that runs parallel to the negotiation; reporting on the hearing itself is in the Timeline. Federal Register correction, 91 FR 9640 ↗
USTR announced a public consultation ahead of the 2027 joint review of USMCA. Written comments go to docket USTR-2026-0595 and requests to appear at a public hearing to docket USTR-2026-0596; “The deadline for submission of comments is January 12, 2027, at 11:59 p.m. EST.” The hearing date and location will be posted on ustr.gov. The Federal Register notice filed the same day (FR Doc. 2026-20341) was published in the Federal Register on October 5, 2026 (91 FR 63379); issued under Section 611 of the USMCA Implementation Act, it asks that hearing requests include a summary of testimony filed through comments.ustr.gov, and sets post-hearing rebuttal comments for seven calendar days after the hearing closes. It records that at the July 1 Free Trade Commission meeting “the United States did not agree to extend the Agreement for a new 16-year term,” so that under Articles 34.7.4–6 “the Commission will meet to conduct a joint review annually.” The notice invites comments on “Any aspect of the operation or implementation of the USMCA; Any issues of compliance with the USMCA; Recommendations for specific actions that USTR should propose ahead of the joint review; Factors affecting the investment climate in North America ...; and Strategies for strengthening North American economic security and competitiveness and cooperation on issues related to non-market policies and practices of other countries.” ICPA analysis, not stated in the source: rules of origin, automotive content and steel are not named; the notice’s topics are general, but docket USTR-2026-0595 is the on-the-record channel for rules-of-origin comments ahead of the 2027 review.

Secretaría de Economía Comunicado No. 93 states that Economy Secretary Marcelo Ebrard “sostuvo hoy un encuentro de trabajo” of almost an hour with USTR Jamieson Greer “en los márgenes de la reunión de ministros de Comercio del G20” in Milwaukee. Ebrard told reporters “Nos estamos acercando (México y Estados Unidos) a muchas cosas. A avanzar, a acercar posiciones, resolver temas” and “Ya cada día estamos más cerca de tener nuevos acuerdos,” framing Mexico’s aim as protecting “los empleos, sus empresas, sus legítimos intereses.” Separately, the comunicado notes that during the G20 Ebrard took part in sessions on the use of food as a trade weapon, forced labor, and industrial overcapacity; it does not say these were raised in the meeting with Greer. The comunicado does not mention the fourth bilateral round, rules of origin or automotive content. ICPA analysis, not stated in the source: As of October 18, 2026, ICPA has located no announced date for the fourth U.S.–Mexico round, which the Sep 23 Timeline entry (El Universal, reported) records as moved to October and which Secretary Ebrard said on October 16 must take place before year-end; current rules of origin requirements are unchanged.

CBP’s CSMS # 70050970 implements Proclamations 11061 (Alcoholic Beverages), 11062 (Dairy) and 11063 (Motor Vehicles), the September 29 exclusions recorded in the Sep 8 entry above and on this page’s Timeline. “As of 12:01 a.m. Eastern Time on September 29, 2026, any entry containing covered products will be unconditionally rejected by U.S. Customs and Border Protection (CBP),” with error codes 239 (FTZ e214 admission), 335 (cargo release) and 886 (entry summary); unreleased ACE entries were cancelled at that time. Covered products imported before 12:01 a.m. ET September 29 remain eligible for entry, and those entered into a bonded warehouse or admitted to a Foreign Trade Zone before that time may be withdrawn for consumption subject to the 50 percent ad valorem duty. A second message the same day, CSMS # 70050117, announced the FTZ and cargo-release error codes. The message does not mention USMCA and sets out no exception for USMCA-qualifying goods.

CBP’s CSMS # 69851916 implements Proclamations 11064 and 11065 for goods entered for consumption or withdrawn from warehouse on or after 12:01 a.m. ET September 15, 2026. The attached list “provides the complete list of HTSUS classifications subject to Section 338 duties as of September 15, 2026, including 122 additional HTSUS classifications now subject to HTSUS 9903.03.12 or HTSUS 9903.03.14.” Ten classifications come off: 2208.30.60 and 2208.70.00 from 9903.03.12, and 2501.00.00 (salt), 2523.29.00 (Portland cement), 2940.00.60, 4803.00.40, 4818.90.00, 7801.10.00, 8537.10.91 and 9507.10.00 from 9903.03.14; the 9903.03.13 dairy list is unchanged. CBP states: “As of September 15, 2026, only goods subject to HTSUS 9903.03.13 are eligible to claim HTSUS 9903.03.15.” The additional duties remain eligible for drawback, and the Chapter 98 and FTZ privileged-foreign-status rules are restated. ICPA analysis, not stated in the source: importers of Canadian-origin goods should re-run the attached “Section 338 Canada Modified HTS LIST eff 091526” against their Chapter 99 filing logic, because coverage changed in both directions, and neither CBP’s August 21 guidance (CSMS # 69606660) nor this message sets out a USMCA exception for covered goods.

On September 8 the President signed five proclamations under Section 338 of the Tariff Act of 1930, published in the Federal Register on September 14 as Proclamations 11061 through 11065. Three exclude the Canadian products listed in their annexes from importation “effective with respect to goods imported on or after 12:01 a.m. eastern time on September 29, 2026”: alcoholic beverages (11061, 91 FR 58311), dairy-related products (11062, 91 FR 58319) and motor-vehicle-sector products (11063, 91 FR 58325). Covered goods imported but not entered for consumption before that time “will remain subject to the 50 percent duty rate established by Proclamation 11048.” Two proclamations (11064 and 11065, the latter at 91 FR 58339) modify the scope of the existing 50 percent duties for goods entered on or after 12:01 a.m. ET September 15, and Proclamation 11065 states that the modified duties “shall apply in addition to duties imposed pursuant to section 232 of the Trade Expansion Act of 1962.” The White House fact sheet describes the scope changes as removing products such as rock salt and cement and adding products “ranging from all-terrain vehicles (ATVs) to additional dairy products,” and states that the Section 338 tariffs “apply to all covered goods regardless of whether a good originates under the U.S.-Mexico-Canada Agreement (USMCA).” Ambassador Greer described the package as “targeted import bans as authorized by Section 338 and a calibration of the underlying Section 338 tariffs,” and the President directed USTR and GSA to remove $50 billion worth of Canadian-origin products from GSA’s Multiple Award Schedules. ICPA analysis, not stated in the source: the action came the same day Canada’s counter-tariffs took effect (CBSA Customs Notice 26-23), and nothing in the proclamations creates a USMCA-origin carve-out from either the duties or the import bans. For this page the point is unchanged from August 22: the USMCA rules of origin are not amended, and CBP’s CSMS # 69606660 already set out no USMCA exception from the Section 338 duties.

The Department of Finance Canada published the operative product list for its September 8 counter-tariffs: surtaxes of 15, 25 and 50 percent across 629 tariff items covering approximately $27.6 billion of U.S. imports, each rate matched to the corresponding U.S. Section 338 or Section 232 rate on the same goods, effective 12:01 a.m., September 8, 2026, in steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics. On origin, the backgrounder states that the tariffs “only apply to goods originating from the U.S., which shall be considered as those goods eligible to be marked as a good of the U.S. in accordance with the Determination of Country of Origin for the Purpose of Marking Goods (CUSMA Countries) Regulations.” Goods in transit to Canada on the day the measures come into force are excluded, and Finance Canada states that administrative detail will follow through CBSA customs notices. ICPA analysis, not stated in the backgrounder: the order defines U.S. origin by reference to the marking regulations only, and does not mention the CUSMA preferential rules of origin. Members should therefore expect the marking test, rather than preferential origin, to govern whether a listed good is caught, and should not assume that claiming CUSMA preference removes a good from the list. ICPA has not located a CBSA customs notice addressing the point. Department of Finance Canada, Aug 26 ↗
In official remarks, Prime Minister Carney announced that Canada is suspending negotiations with the United States, saying the U.S. “asked too much and offered too little.” Canada will match the new U.S. tariffs dollar for dollar, targeting steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics, effective the Tuesday after Labour Day, September 8, 2026. Carney also stated that the United States has imposed tariffs that violate its commitments under CUSMA. Members exporting to Canada should expect duties payable on covered goods to change from September 8; the specific tariff list and any remission mechanics are expected from the Department of Finance Canada. No implementing instrument had been published as of August 24.
CBP issued CSMS # 69606660 implementing the three Section 338 proclamations covering Canadian dairy, alcoholic beverages, and motor vehicles, with coverage extending to items such as wine and cement. The additional 50 percent ad valorem duty applies to Canadian-origin goods entered or withdrawn for consumption on or after 12:01 a.m. ET on August 22, 2026, after a three-day suspension of the original August 19 date. Entries must be filed under new HTSUS Chapter 99 headings 9903.03.12 through 9903.03.16, the last two carrying a zero rate for excluded categories including Section 232 goods and certain civil-aircraft components. The guidance does not mention USMCA and sets out no exception for originating goods; the White House states the Section 338 tariffs “apply to all covered goods regardless of whether a good originates under the U.S.-Mexico-Canada Agreement (USMCA).” This does not amend Chapter 4 or Annex 4-B, but it sharply reduces the practical value of origin qualification on the covered Canadian tariff lines.
Reuters reported that the U.S. push for a 50 percent U.S.-content requirement for preferential auto access remains an active dispute heading into the September round, with Mexico resisting and linking any concessions to relief from U.S. national-security tariffs on autos and metals. Still not confirmed in published government text. See Current Rule vs. Proposed Change.
USTR’s forced-labor Section 301 action imposed tariffs on 60 economies, including Canada and Mexico. Mexico’s Economy Minister said the same day it would produce no practical change for Mexico because USMCA-compliant goods remain exempt, with roughly 85 percent of Mexican exports to the United States staying tariff-free if they satisfy the rules of origin. This is not a treaty amendment, but it sharpens the immediate commercial value of a defensible origin claim.
The USTR–Mexico joint statement said Ambassador Greer and President Sheinbaum agreed on the urgency of growing North American manufacturing, strengthening regional supply chains, and addressing free-riding from non-parties. ICPA analysis, not stated in the source: that framing ties the review to economic-security and non-market-input concerns, not merely percentage thresholds, and is a leading interpretive clue for where future ROO pressure may land.
USTR and Mexico completed the third bilateral round in Mexico City, with Ambassador Greer meeting President Sheinbaum. The agenda covered automobiles, steel and aluminum and derivative products, economic security, labor, agriculture, and electronic payment services. The July 23 joint statement directs both teams to convene a fourth bilateral round in Washington, D.C. in September 2026. No negotiating text was published. Canada is not party to this bilateral track.
Testifying before the Senate Finance Committee, Ambassador Greer said the United States hopes to reach interim arrangements with Canada and Mexico by the end of 2026, and that thornier issues, including tighter automotive rules of origin, would likely require more time and further discussion with Congress, pushing full resolution into 2027.
At the first joint review, the United States did not agree to renew USMCA in its current form, triggering annual reviews through 2036 under Article 34.7.4. Article 34.7 still allows the parties to extend the agreement later if all three governments confirm in writing that they wish to do so.
A USMCA Chapter 31 panel ruled against the United States, confirming the more flexible roll-up method advocated by Canada and Mexico for calculating a vehicle’s regional value content. USTR disagreed; the agreement provides no mechanism to appeal panel decisions. See Disputes & Panel Decisions.
Overview
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 in the Appendix to Annex 4-B, 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. The negotiation picture sharpened after July 19: the third bilateral round concluded on July 23, a fourth round was set for September, and Ambassador Greer signaled that ROO is likely to be handled in stages, with interim arrangements sought by year-end and the harder legal work slipping into 2027. No published agreement amending the current Rules of Origin has been located as of July 26, 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.
Controlling Authorities
The legal texts that govern origin qualification today, unaffected by ongoing negotiations.
Current Rule vs. Proposed Change
The most consequential comparisons on this page. Nothing here is legally effective unless labeled “confirmed by controlling authority.”
75% North American RVC under the net cost method for passenger vehicles and light trucks; for Table A.1 core parts, 75% net cost or 85% transaction value where the rule allows (EV propulsion batteries of 8507.60 excepted), per Article 3 of the Appendix to Annex 4-B, with no country-specific content share.
A reported U.S. push to raise North American content as high as 82%, paired with a new requirement that vehicles contain 50% U.S.-made content for preferential access. Reuters reported on July 24, 2026 that the 50% demand remains an active dispute and that Mexico strongly opposes it. Not located in published government text.
No official proposal has been published. As of August 24, 2026 the 50 percent U.S.-content and 82 percent regional-value-content figures remain trade-press reporting only. ICPA re-checked this cycle for a notice of proposed rulemaking, a Federal Register notice, published negotiating text, or a joint statement establishing a U.S.-content requirement under the USMCA rules of origin, and found none. Two official items published in August were examined and do not qualify: the Commerce Department’s August 19 final rule amending U.S.-content submission procedures for USMCA-qualifying automobiles governs Section 232 offset documentation, not USMCA origin, and the USITC’s 2027 automotive-rules investigation is an economic-analysis track, not a proposal. The treaty baseline is intact.
The evidentiary weight of this proposal has increased without changing its legal status. Before July 19, the figures were an older, single-source rumor attached to the May round; after July 24 they are tied explicitly to the September round and to Mexico’s active resistance, with reporting indicating Mexico has refused even a 1% country-specific requirement. A U.S.-specific content rule would fall hardest on Canadian parts content, which is one reason it also carries trilateral-structure risk. It is still reported, not confirmed 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.
At least 70% by value of the vehicle producer’s steel purchases, and separately of its aluminum purchases, in the USMCA territories must be originating goods (Article 6 of the Appendix to Annex 4-B); a supplier’s North American location alone does not establish origin. 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, and the July 23 statement centered supply chains and non-party free-riding. No specific proposed text located.
Disputes & Panel Decisions
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 26, 2026. USTR’s current Chapter 31 disputes page still lists the existing Auto ROO (Mexico) matter and does not show a new public ROO-specific Chapter 31 case filed after 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. The immediate ROO battleground has shifted back to negotiation rather than litigation.
Canada & Trilateral Structure Watch
A structural feature of the current phase, not a one-off meeting format. Rules of origin are inherently trilateral, so a bilateral reworking carries consequences beyond the U.S.–Mexico lane.
Reuters reported on July 22, 2026 that separate U.S. negotiating tracks with Canada and Mexico are testing the trilateral structure of USMCA, with the U.S.–Mexico talks described as several months more advanced and Canada still outside the formal bilateral round structure that set the September Washington meeting. The same reporting warned that separate tracks could create terms the third country later has to accept or contest.
Why this matters for origin: cumulation, RVC counting, and steel and aluminum sourcing all assume a North American architecture rather than a country-by-country one. A bilateral reworking of automotive ROO, especially one with U.S.-specific content counting, would have consequences far beyond the U.S.–Mexico lane and could destabilize the legal logic of current Canadian participation in the automotive ecosystem.
Open Legal Issues
Recurring and developing issue-areas ICPA is tracking beyond the headline automotive dispute. Status reflects the most recent verification pass; none of these has been adopted as a legally effective change.
Origin Certification & Verification
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.
- Importer-based certifications
- Producer & exporter recordkeeping
- Supplier affidavits
- Confidential business information
- Tracing of steel, aluminum, batteries & minerals
- Verification questionnaires & site visits
- Denials based on inadequate documentation
- Consistency across CBP, CBSA & Mexican customs
- Post-importation corrections & refunds
- Fraud, transshipment & circumvention
- Confirm HTS classifications
- Map applicable Annex 4-B rules
- Identify high-risk non-originating inputs
- Review supplier affidavit coverage
- Test bill-of-material data quality
- Review steel, aluminum, battery & mineral sourcing
- Compare USMCA utilization to MFN entry
- Confirm record-retention practices
- Review verification readiness
- Identify products with narrow qualification margins

Seeks stronger rules of origin for automotive and key industrial goods, more North American and U.S. production, 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, and now favors interim arrangements by year-end with harder ROO work in 2027.
Supports continuing and extending USMCA while treating automotive rules, evolving origin requirements, verification, steel, aluminum, and economic security as active subjects. Opposes a U.S.-specific automotive content threshold and reportedly links concessions to relief from U.S. national-security tariffs on autos and metals.
Emphasizes stability, predictability, and preserving the integrated North American market, and describes the review as a process for assessing and improving the agreement rather than a wholesale reopening. Currently outside the formal U.S.–Mexico bilateral round structure carrying the live ROO agenda.

| U.S. vehicle production | −15,037 vehicles |
| Employment in U.S. parts production | +5,387 workers |
| Employment in U.S. steel production | +2,463 workers |
| Employment in U.S. vehicle production | −302 workers |
| Revenue in U.S. parts production | +$3.419 billion |

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. This suggests future proposals will likely be argued in distributional terms, who wins inside the value chain, rather than as transformational whole-economy changes.

Research Gaps & Open Issues
Reviewed and updated with each page verification pass.
- Official negotiating text has not been published for any proposed automotive RVC change
- Exact numerical automotive proposals (82% / 50%) not confirmed by government source; still sourced only to secondary reporting
- Canada’s formal response to bilateral U.S.–Mexico proposals, and whether it re-enters the formal round structure, not located
- Specific industrial-goods product rules under discussion not yet identified in public text
- Proposed verification or supplier-disclosure changes not described in published text; no new Origin Committee or Sub-Committee on Origin Verification records posted since July 19
- Legal mechanism for any ownership- or entity-based origin restriction remains unclear
- Whether rules of origin would be included in any interim U.S. arrangement in 2026, or held for the 2027 phase, not addressed in a public government document. ICPA analysis: the CCE’s October 5 private-sector account in Milenio says rules of origin have moved to next year’s review (see the Oct 5 Timeline entry); it is not a government statement
- Sector-level preferential utilization data incomplete for 2025–2026

About this tracker
The USMCA Joint Review Tracker is published by the International Compliance Professionals Association (ICPA). It follows the 2026 USMCA joint review under Article 34.7: negotiating rounds, government positions, legal status, tariff and customs actions, and what each change means for importers and exporters. It is a policy and compliance tracker, not a trade-flow data dashboard.
Updated weekly and when a significant development breaks. It covers automotive, agriculture, labor, digital trade, de minimis, steel and aluminum, economic security and rules of origin, and it is built on primary sources from USTR, CBP, the White House, the Federal Register and the governments of Canada and Mexico, with every item marked as confirmed or reported.
This tracker is researched and maintained by Heather Tschirhart, who leads ICPA’s trade research and data work.
