Formal talks to save the U.S. Mexico Canada Agreement (USMCA) enter a decisive phase this week, with Washington expected to declare on June 30 that it will not commit to extending the 32 year old North American trade pact, triggering a decade long sunset process that carries real economic stakes for automakers, exporters and cross border supply chains across all three countries.
At a Glance
- Trade chiefs from the U.S., Mexico and Canada were scheduled to meet virtually to declare whether they want to extend USMCA for another 16 years.
- A non extension declaration triggers a six year review session under a sunset clause negotiated during President Trump's first term.
- Failure to agree on revisions would keep the pact in indefinite limbo, with annual reviews for 10 years before a 2036 expiration.
- U.S. Trade Representative Jamieson Greer has scheduled a third round of negotiations with Mexico for the week of July 20.
- Trump has repeatedly favored steep tariffs on Mexican and Canadian autos, steel and aluminum over renewing the agreement.
What the Sunset Clause Actually Triggers
The mechanism at play here is the joint review provision built into USMCA when it replaced the 1994 North American Free Trade Agreement in 2020. Every six years, the three governments must affirmatively agree to extend the deal for another 16 years. Skip that step, as Washington is expected to do, and the countries enter a rolling ten year window of annual reviews. If no consensus emerges by the end of that decade, the pact lapses automatically on July 1, 2036. That is a distinct process from the separate termination clause, which lets any single leader, Trump included, pull the United States out entirely with six months notice. The sunset review does not force an exit; it just keeps the clock ticking and the uncertainty compounding year after year.
Greta Peisch, a former USTR general counsel now a trade partner at Wiley Rein in Washington, framed the expected outcome bluntly: July 1 would come and go without U.S. confirmation of intent to extend. She also flagged an open question that matters for markets and negotiators alike, whether the administration's post meeting statement will spell out specific demands or leave the substance vague for now.
The Substantive Fight: Autos, Content Rules and China
The procedural sunset declaration is almost a sideshow compared to what is actually being contested at the negotiating table. The U.S. side has pushed for sweeping increases to North American and U.S. specific content requirements in automotive manufacturing, a direct challenge to existing rules of origin that automakers spent years and billions of dollars retooling supply chains to meet. Washington is also seeking tighter trade protections designed to prevent Chinese goods, components and capital from using Mexican or Canadian assembly as a backdoor into the USMCA tariff free zone.
USTR Greer has already locked in a third round of bilateral talks with Mexico for the week of July 20, a scheduling decision that signals the administration intends to keep grinding on these issues regardless of what happens with the sunset declaration. That timeline matters: it tells markets and industry stakeholders that the review clock and the substantive renegotiation are running on parallel, not sequential, tracks.
Why Trump Soured on the Deal He Signed
Trump's first administration negotiated USMCA and he called its 2020 launch the fairest, most balanced and beneficial trade agreement ever signed into law by the United States. That enthusiasm did not survive contact with the trade data. The U.S. goods trade deficit with Mexico widened in the years that followed, a trend partly driven by companies rerouting supply chains out of China and into Mexico to dodge the steep tariffs Trump himself imposed on Chinese goods during his first term. The irony is not lost on trade analysts: tariff policy aimed at China helped inflate the very bilateral deficit with Mexico that Trump now cites as justification for rethinking USMCA.
Trump has said repeatedly that he does not want to renew the agreement as currently structured, expressing a preference for the tariff regime he has already put in place on Mexican and Canadian autos, steel and aluminum. That stance complicates the negotiating dynamic considerably, because it suggests the U.S. position may not be a genuine effort to modernize USMCA so much as a preference for unilateral tariff leverage over a negotiated multilateral framework.
What a Prolonged Standoff Means for the Region
An indefinite limbo scenario, where none of the three governments can agree on revisions, does not kill USMCA overnight. It does, however, inject a decade of recurring uncertainty into investment decisions tied to automotive plants, parts suppliers and any manufacturer weighing where to site new capacity. Annual review sessions for ten straight years give each government repeated leverage points to reopen contentious issues, meaning the content rule disputes and China related trade protections now on the table could resurface year after year rather than getting resolved once and settled.
For Mexico and Canada, the calculus is different but no less pressing. Both governments have significant export exposure tied to preferential USMCA access, particularly in autos, and both face the prospect of negotiating against an administration that has shown a clear preference for tariffs over treaty commitments. The scheduled July round of talks with Mexico suggests Washington intends to keep pressing bilateral leverage even as the trilateral sunset process unfolds on its own separate timeline.
Frequently Asked Questions
What happens if the U.S. does not agree to extend USMCA this week?
A non extension declaration starts a six year review session under the sunset clause. This does not end the agreement immediately; it begins a process of annual reviews for up to ten years, after which USMCA would expire on July 1, 2036 if no agreement is reached.
Is the sunset review the same as terminating USMCA?
No. The sunset review is a separate mechanism from the termination clause. Termination allows the U.S. president, or the Mexican or Canadian leader, to withdraw the United States from the pact unilaterally with six months notice, regardless of where the review process stands.
What are the main sticking points in the renegotiation?
The U.S. is seeking higher North American and U.S. specific content requirements for automotive production, along with stronger measures to prevent Chinese goods from gaining indirect access to the USMCA tariff free zone through Mexico or Canada.
Why did Trump's view of USMCA change since 2020?
The U.S. goods trade deficit with Mexico grew after 2020, partly because companies shifted supply chains from China to Mexico to avoid tariffs Trump imposed on Chinese goods. Trump has since said he prefers using tariffs on Mexican and Canadian autos, steel and aluminum over renewing the agreement as is.
Where This Leaves the Negotiating Calendar
The next concrete marker is the week of July 20, when U.S. and Mexican trade officials sit down for a third round of bilateral talks. Whatever language emerges from the trade chiefs' virtual meeting around the sunset declaration will likely set the tone, but the real substance, content rules, China related safeguards, and the broader question of whether Washington wants a treaty or a tariff regime, gets fought out in those bilateral sessions. With a full decade of review cycles now in play, this week's declaration is less an ending than the start of a long, recurring negotiation.
