The United States is expected to formally notify its North American partners that it will not extend the United States Mexico Canada Agreement (USMCA), triggering the pact’s sunset review process and beginning a potential 10-year countdown to its expiry in 2036. While the move does not immediately terminate the agreement, it opens a prolonged period of negotiations during which the three countries will seek to resolve disputes over automotive rules, regional manufacturing, market access and measures to prevent Chinese goods from benefiting from preferential trade provisions.
The decision reflects the Trump administration’s push to reshape North American trade around greater US manufacturing content and stricter supply chain rules rather than preserving the agreement in its current form.
Sunset clause launches a decade of negotiations
The notification activates the USMCA’s sunset review mechanism, requiring annual consultations if no agreement is reached to renew the pact for another 16 years. Rather than ending the agreement immediately, the process creates a structured but uncertain negotiation period that could last until the agreement expires in 2036 unless the three countries reach a revised deal.
The review mechanism is intended to keep the agreement under continuous assessment but also introduces long-term uncertainty for businesses operating across North America.

Washington pushes for tougher automotive rules
The United States is seeking significant changes to the agreement’s rules of origin, particularly in the automotive sector. Washington wants a substantially larger share of vehicle components to be produced in the United States while increasing overall North American content requirements to reduce dependence on Asian supply chains.
The proposals form part of a broader industrial strategy aimed at strengthening domestic manufacturing, creating more US jobs and preventing third-country producers, particularly China, from indirectly accessing preferential North American trade benefits.
US and Mexico lead negotiations while Canada remains sidelined
Current negotiations are taking place primarily between Washington and Mexico, with Canada playing a more limited role amid ongoing bilateral trade disputes with the United States.
The narrower negotiating format highlights differing priorities within the three-country partnership and raises questions about whether a comprehensive trilateral agreement can be achieved without parallel negotiations involving Ottawa.
Trade policy reflects broader supply chain strategy
The proposed revisions extend beyond traditional tariff issues and reflect a wider effort to reorganise North American manufacturing. By tightening content requirements and strengthening origin rules, the United States aims to encourage companies to relocate production closer to home while limiting opportunities for Chinese manufacturers to circumvent trade restrictions through regional supply chains.
This shift illustrates how trade policy has become increasingly intertwined with industrial policy and national economic security objectives.
Businesses face prolonged policy uncertainty
The activation of the sunset clause is unlikely to disrupt trade immediately, but it introduces a prolonged period of uncertainty for manufacturers, exporters and investors whose operations depend on integrated North American supply chains.
Companies may delay long-term investment decisions until greater clarity emerges on future tariff structures, production requirements and the overall direction of regional trade policy.
Future Outlook
Negotiations are expected to intensify over the coming months as the United States continues pressing for stricter manufacturing rules and stronger regional content requirements. While Mexico appears willing to negotiate toward shared industrial objectives, Canada’s future role remains less certain given unresolved bilateral trade disputes.
Unless the three countries reach a mutually acceptable compromise, the USMCA could remain under annual review for the next decade, prolonging uncertainty for businesses while reshaping North America’s manufacturing landscape. The outcome of these negotiations will likely determine not only the future of the trade agreement but also the competitiveness of regional supply chains and the balance between economic integration and national industrial policy.
