U.S. exit from USMCA starts decade long countdown

The USMCA review deadline lands on July 1, and the number that matters most is 2036, the year the trade pact could fully expire if Washington, Mexico City and Ottawa fail to agree on renewal terms during the next decade of scheduled check ins. The Trump administration is expected to formally decline to extend the agreement outright, triggering a review process rather than an immediate exit.

At a Glance

• USMCA's sunset clause requires a formal review declaration around July 1, 2025, six years after the pact took effect.
• Failure to agree on extension terms means annual reviews for 10 years, with expiration set for July 1, 2036 absent a deal.
• USTR Jamieson Greer has scheduled a third round of talks with Mexico for the week of July 20.
• Key disputes center on regional automotive content rules and mechanisms to keep Chinese goods from routing through North America duty free.
• A separate termination clause lets any of the three countries trigger a six month U.S. withdrawal process, independent of the sunset review.

What the Sunset Clause Actually Requires

USMCA, which replaced NAFTA in 2020, was built with a review and sunset mechanism negotiated during Trump's first term specifically to force periodic renegotiation. Every six years, the three governments must formally state whether they want to extend the agreement for another 16 years. If they decline or fail to reach consensus, the treaty doesn't die immediately. Instead it enters a cycle of annual reviews stretching out for a decade, with a hard expiration date of July 1, 2036 if no resolution emerges.

That structure means Wednesday's expected non-extension declaration is procedural rather than terminal. Trade officials from all three countries plan to meet virtually to record their positions, but the practical effect on ongoing negotiations over content rules and tariff exposure will be minimal. Greer has already locked in a third round of bilateral talks with Mexico for the week of July 20, an indication that the substantive bargaining continues regardless of what gets said on the sunset deadline itself.

The Core Disputes: Autos and China

Two issues dominate the renegotiation agenda. The first is regional content requirements in automotive manufacturing, where the U.S. is pushing to raise thresholds for how much of a vehicle's value must originate in the U.S. or North America broadly to qualify for USMCA's tariff free treatment. The second is a push for stronger trade defense mechanisms aimed at preventing Chinese goods from entering U.S. markets duty free by way of Mexican or Canadian intermediaries.

Both issues trace back to the same underlying grievance: the U.S. goods trade deficit with Mexico has widened since USMCA's 2020 launch, and a meaningful share of that shift reflects supply chain realignment away from China following Trump's tariffs on Chinese imports during his first term. Companies moved production to Mexico partly to sidestep those tariffs, which inflated Mexico's trade surplus with the U.S. even as it reduced direct U.S. exposure to Chinese manufacturing.

Greta Peisch, a former USTR general counsel now a trade partner at Wiley Rein in Washington, expects the U.S. to withhold a formal extension commitment on July 1 without necessarily detailing its full negotiating position publicly. That ambiguity matters for markets and manufacturers trying to plan multiyear investment decisions around uncertain rules of origin.

Termination Clause Versus Sunset Review

It helps to separate two distinct legal mechanisms embedded in USMCA. The sunset review, now activating, is a scheduled, six year checkpoint that doesn't require any party to act unilaterally: absent agreement, the treaty simply continues under annual review until 2036. The termination clause is different. It allows Trump, or his Mexican or Canadian counterparts, to unilaterally exit the agreement at any time, initiating a six month withdrawal process for the United States.

Trump has not invoked the termination clause, and nothing in the current schedule suggests he intends to. His public comments instead favor relying on tariffs he has already imposed on Mexican and Canadian autos, steel and aluminum rather than renewing USMCA on its existing terms. That posture complicates the picture: Washington appears to want leverage from both the tariff regime and the renegotiation process simultaneously, without committing to extend the underlying free trade architecture.

How Trump's Position Has Shifted

The contrast between 2020 and now is stark. Trump's first administration negotiated USMCA to replace the 1994 NAFTA framework, and he called its launch
