Mexico Faces Escalating US Tariffs: Section 301 Investigations, Retaliatory Duties, and USMCA Trade Tensions in 2026

Welcome to Mexico Tariff News and Tracker. Today, tensions are escalating in US-Mexico trade as President Trump's aggressive tariff strategy zeroes in on our southern neighbor. According to the Trade Compliance Resource Hub's Trump 2.0 tariff tracker, Section 301 investigations targeting Mexico were threatened as recently as March 11, 2026, with rates still to be determined, signaling potential new duties on Mexican goods amid broader USMCA reviews. Mexico is firing back hard. Sunsirs reports that the Mexican government officially incorporated temporary tariff measures into its General Import and Export Tax Law, slapping additional duties on 1,463 tariff codes from non-FTA countries like China, with rates hitting 35% to 45% and up to 50% in some cases. This directly counters US pressures, protecting Mexican industries from cheap imports while US threats loom. Adding fuel, AFS Law's March 2026 customs update highlights the US Supreme Court's ruling that IEEPA tariffs were unlawful, pausing refunds but paving the way for Section 301 and 232 replacements. Mexico benefits from exemptions in the temporary 10% Section 122 global surcharge—effective until July 24, 2026—including USMCA duty-free goods, but stackable duties on steel, aluminum, autos, and trucks could still bite, with rates from 10% to 25% on Mexican-origin parts. BNamericas warns a US forced labor probe into global supply chains rekindles tariff risks for Mexico among 60 countries, potentially hiking costs on key exports like autos and agriculture. Argus Media notes the US plans new tariffs on major partners, keeping Mexico in the crosshairs as Trump pushes reciprocal deals. These moves could disrupt billions in cross-border trade, from avocados to vehicles. Stay vigilant, listeners—tariff rates are fluid, with Section 301 details pending.
