The Agreement

One agreement. Three names. A working guide.

USMCA, CUSMA and T-MEC are the same legal text, ratified by the United States, Canada and Mexico under their own names. This guide explains what it covers, chapter by chapter, and links every chapter to the AmerNor Trade Intelligence Engine.

What every business should know

  • In force since July 1, 2020

    It replaced NAFTA (1994). NAFTA still matters for contracts, investments and disputes that began before 2020.

  • Joint review in 2026

    On the sixth anniversary, the three countries conduct a joint review (Article 34.7). Without confirmation of extension, the agreement ends 16 years after entry into force, with annual reviews in the meantime.

  • Duty-free only if the goods qualify

    Preferential treatment depends on the rules of origin (Chapter 4) and a valid certification of origin (Chapter 5). Goods that do not qualify pay normal tariffs.

  • Not every chapter binds all three countries

    Government procurement (Chapter 13) applies between the United States and Mexico only. Investor–state dispute settlement (Chapter 14) is available between the United States and Mexico; Canada's legacy NAFTA claims window closed in 2023.

  • Anti-dumping review panels remain

    Chapter 10 keeps binational panel review of anti-dumping and countervailing duty decisions, used in disputes such as softwood lumber.

  • Some measures sit outside the agreement

    National-security tariffs and other domestic measures can apply alongside it. Always check the current status with a dated source.
