USMCA — origin rules, RVC/LVC, certifications, enforcement.

The United States–Mexico–Canada Agreement (USMCA) replaced NAFTA in 2020 and governs trade among the three countries. USMCA-origin treatment requires meeting specific rules of origin, regional value content (RVC), and — for autos — labor value content (LVC) thresholds. TariffSignals tracks USTR enforcement actions, Federal Register notices, CBP CSMS guidance on USMCA certifications, and the joint review process leading to the 2026 statutory review.
