Since 15 August 2025, rule 3.7.35 of Mexico's foreign trade rules applies a 33.5% global rate to courier imports from countries without a trade agreement with Mexico, against 19% before. US and Canadian courier shipments keep preferential treatment: exempt under $50, 17% from $50 to $117 and 19% above. Since 1 January 2026 tariffs of 5% to 50% apply on 1,463 tariff lines from non-agreement countries such as China, India and South Korea, with textiles at 25% to 35%.
