Overview
- The United States refused on July 1 to accept a 16‑year automatic extension, putting the T‑MEC into annual review while the agreement remains legally in force.
- The Trump administration has combined the review with new tariff measures, including a 10% package that names Mexico and a separate higher tariff action against Canada, and has used domestic authorities such as Section 301 and Section 338 to pressure counterparts.
- Negotiators have completed multiple rounds of talks and expect further meetings in September, but officials and legal experts say the process is likely to be prolonged and uneven, with sector-by-sector deals possible.
- Rules of origin have become the central dispute: U.S. proposals aim to raise regional and U.S.-made content in goods while Mexico rejects quotas that would shift where engines, chips and other high-value components are built; origin rules determine whether goods keep tariff exemptions.
- Businesses and banks report growing caution: investment decisions and nearshoring plans have been delayed, some firms are adjusting supply chains (for example shifts in auto production), and analysts warn the outcome will shape jobs, plant location and investment across North America into 2027.
