The US government has exempted Mexico and Canada from its recent 10% global tariffs, but that doesn't mean North American trade is in the clear.
With the United States-Mexico-Canada Agreement’s (USMCA) first joint review scheduled to begin on July 1, 2026, trade uncertainty is back on the table. The review could reshape rules of origin, labor enforcement, sector-specific duties, and even the structure of the agreement itself.
What is USMCA?
The United States-Mexico-Canada Agreement (USMCA) agreement governs commerce between the three North American countries (the US, Mexico, and Canada). It replaced the North American Free Trade Agreement (NAFTA) in 2020, introducing updated provisions around rules of origin, labor rights, digital trade, and agricultural market access.
Unlike a standard trade deal, negotiators modernized the USMCA with a sunset clause. It’s subject to a joint review every six years, beginning in 2026, with an automatic expiry after 16 years unless renewed. This review mechanism means the USMCA agreement is periodically relitigated.
What does the July 1, 2026, USMCA review mean?
July 1, 2026, is a high-stakes day for North American trade. The Free Trade Commission (comprising trade ministers from all three countries) convenes to begin the first formal joint review, and the outcome will either lock in 16 years of relative stability or trigger annual renegotiations through 2036, keeping organizations in a sustained state of uncertainty for the better part of a decade.
Preliminary negotiations are already underway. The US Trade Representative has held meetings with Mexico's Secretary of Economy, with discussions centering on rules of origin for key industrial goods, critical minerals, and alignment on external trade policy, particularly to counter the influx of dumped manufactured goods entering the North American region from outside countries.
The US-Canada dynamic, however, is considerably more tense. Reports indicate growing friction between Washington and Ottawa, with some speculation about a bilateral deal between the US and Mexico that could sideline Canada, though this remains an outlier scenario. Meanwhile, Canada and Mexico have begun their own bilateral economic dialogue, adding a further layer of complexity to the negotiations.
All three governments issued public comment requests in September 2025, and hearings ran through December. Governments are now consolidating that feedback to define enforcement priorities ahead of the formal review.
Four possible outcomes
Despite strong incentives for all three countries to maintain the USMCA trade agreement, the review creates real compliance and policy risks across several scenarios.
| Scenario | Business impact | Likelihood |
| Extended with no major changes | Greatest stability. Organizations maintain current sourcing and investment strategies with minimal disruption. | Low–medium |
| Extended with targeted changes | Reforms to rules of origin, labor enforcement in Mexico, and certain product access in Canada raise compliance costs. Most aligned with current US trade posture. | High |
| No consensus reached | USMCA stays active but enters annual reviews through 2036. Uncertainty could drive shorter-term supplier contracts and contingency clauses. | Medium |
| Tariffs undermine the agreement | Cost increases across North American trade, potential retaliatory actions, and renegotiation pressure, particularly given the ongoing use of tariffs under non-International Emergency Economic Powers Act (IEEPA) legal authority. | Medium |
Sectors most at risk
Enforcement risks from the USMCA review are unlikely to be spread evenly. Four sectors face heightened exposure:
- Automotive carries the highest operational risk. Rules of origin, labor enforcement, and tariff pressure will likely drive more frequent origin audits across manufacturers and suppliers.
- Electronics faces growing scrutiny as nearshoring has expanded Mexico-based manufacturing. Products with components of Chinese origin will attract heightened attention—a direct byproduct of US-China trade policy intersecting with USMCA enforcement (read Disruptions in Mexico Are Reshaping Nearshoring).
- Energy risk is driven more by political tension than rule changes. Rather than formal amendments, the sector faces mounting pressure to align with policy directives as negotiations heat up.
- Agriculture sits at the intersection of two live disputes: US-Canada dairy access friction and implementation gaps with Mexico. Expect Washington to push harder on both fronts, with retaliation from either partner a real possibility.
| Date | What to watch for |
| Now–March 2026 | Governments consolidate enforcement priorities as companies and trade organizations finalize lobbying positions. |
| March–April 2026 | Increased inter-agency coordination; early enforcement actions and inquiries signal where scrutiny will land. |
| May 2026 | Governments begin publicly signaling expectations, including sector-specific priorities and red lines. |
| June 2026 | Governments finalize negotiating positions; businesses should have contingency plans and sourcing assumptions locked in. Market volatility from media coverage is possible even without formal rule changes. |
| July 1, 2026 | Free Trade Commission convenes. The review officially begins. The outcome determines whether the USMCA agreement is extended for 16 years or enters a cycle of annual reviews. |
What businesses should do now
Organizations with North American supply chains should be taking three actions now:
- Map your exposure: Understand which suppliers, sourcing locations, and product categories are most vulnerable to changes in rules of origin, labor enforcement, or sector-specific tariffs (read Why Supply Chain Mapping Matters).
- Run scenario models: Use the four scenarios above to pressure-test your sourcing strategy and cost assumptions.
- Build flexibility into contracts: Build contingency clauses into supplier agreements and align approval workflows to the pace of policy shifts.
The lead-up matters as much as the outcome. Organizations that prepare now won't be caught off guard when July 1 arrives.
