Mexico Faces Mixed Tariff Outlook After Supreme Court Ruling Strikes Down Broad USMCA Duties

Welcome to Mexico Tariff News and Tracker, your essential update on the latest U.S. trade moves impacting our southern neighbor. In the wake of the Supreme Court's February 2026 ruling striking down broad IEEPA tariffs, the Trump administration has pivoted aggressively, but Mexico faces a mixed landscape. According to the Trump Tariff Tracker from Baker Botts reported on JDSupra, a 25% ad valorem duty on all non-USMCA-qualifying products from Mexico was implemented in March and April 2025, only to be struck down on February 20, 2026, alongside similar measures on Canada and others. This ruling halted what could have been a major hit to Mexican exports like autos and parts, now protected under USMCA exemptions. A temporary 10% global tariff under Section 122 of the Trade Act remains in effect until July 24, 2026, but explicitly excludes USMCA-qualifying goods from Mexico and Canada, per the same tracker. Treasury Secretary Scott Bessent, speaking at a Wall Street Journal event as reported by Bloomberg Government, announced that full tariff rates could return by early July through Section 301 investigations—already underway on issues like industrial overcapacity—offering a more court-tested path than the overturned emergency powers. Wipfli reports new Section 232 tariffs took effect April 2, 2026, on steel, aluminum, copper, and pharmaceuticals, hitting Mexican metal exports hard at up to 50% on full customs value, though USMCA-compliant autos dodge the 25% automobile levy still active globally. Mexico's reprieve on broad duties underscores USMCA's resilience amid the chaos, but manufacturers warn of supply chain ripples. Federal Reserve research via Fortune shows U.S. businesses and consumers now bear nearly 90% of tariff costs, potentially slowing cross-border trade.
