Presidential decree signed by President Claudia Sheinbaum and published in the evening edition of the Diario Oficial de la Federación on 23 April 2026, in force 24 April 2026. The decree amends the Tariff of the Ley de los Impuestos Generales de Importación y de Exportación (LIGIE/TIGIE) and the Decreto que establece diversos Programas de Promoción Sectorial (PROSEC), imposing MFN import duties at 5%, 10%, 15%, 25%, 30% or 35% ad valorem on 185 tariff fractions covering chemical products, cosmetics, paper and cardboard, textiles, steel, graphic arts, aluminum manufactures, auto parts, electrical material, bicycles, musical instruments, furniture, wind turbines, and trailers. Goods originating in countries with which Mexico has a free-trade agreement remain eligible for preferential treatment, so practical incidence falls on China and other non-FTA suppliers (Korea, India, Vietnam, Thailand, Brazil, Indonesia, Taiwan, UAE, South Africa). Paired PROSEC modifications add tariff fractions to Article 5 sections I, II.b and XIX (electrical, electronic, automotive and auto-parts industries) at exempt (EX) rates.

Decree reforming various tariff fractions of the General Import and Export Duties Tariff (TIGIE), published in the Diario Oficial de la Federación on 29 December 2025 and in force 1 January 2026. The reform, approved by Congress as a statutory amendment to the LIGIE (Chamber of Deputies and Senate, Dec 2025) and signed by President Claudia Sheinbaum, raises MFN import duties to between 5% and 50% ad valorem on 1,463 tariff lines covering more than 20 chapters of the TIGIE, spanning automotive, auto parts, textiles, apparel, footwear, steel, aluminum, plastics, paper, leather, furniture, glass, toys, appliances and cosmetics. The increases apply only to goods originating in countries without a free trade agreement with Mexico — principally China, South Korea, India, Vietnam, Thailand, Brazil, Indonesia, Chinese Taipei, the UAE, and South Africa. The decree formalises at statutory level the September 2024 Sheinbaum executive order placing a 50% duty on finished passenger vehicles from non-FTA states and is framed by the Secretaría de Economía and SHCP as the operational tariff instrument of Plan México (2025-01-21).

On 10 November 2025 the Mexican government published a decree in the Diario Oficial de la Federación (DOF) modifying the Tarifa de la Ley de los Impuestos Generales de Importación y de Exportación (LIGIE) to raise most-favoured-nation import tariffs on sugar and sugar-derivative products (raw, refined, liquid and invert sugar, and related high-sugar-content goods across roughly eight six-digit tariff subheadings) to between 156% and 210.44% ad valorem, replacing the prior specific-duty regime of USD 0.33–0.39 per kilogram. The decree entered into force 11 November 2025, the day after publication, and applies to imports from WTO members that lack a preferential trade agreement with Mexico. The Secretaría de Economía framed the increase as protection for the domestic sugarcane agro-industry against a national oversupply and falling international reference prices.

Mexico's tax authority (SAT), acting under SHCP, published the Cuarta Resolución de Modificaciones a las Reglas Generales de Comercio Exterior para 2025 in the Diario Oficial de la Federación on 28 July 2025, raising the flat tax rate applied under the simplified customs regime for low-value courier and parcel shipments (goods valued at USD 2,500 or less) from 19% to 33.5%, effective 15 August 2025. The increase applies to shipments from countries without a free trade agreement with Mexico — in practice overwhelmingly China-origin goods — and is aimed at cross-border e-commerce platforms (Shein, Temu, AliExpress) as well as triangulated goods routed through courier channels by other importers including large retailers. The measure is framed by SHCP as combating under-invoicing and non-tariff-preference triangulation via the courier de minimis channel.

Mexico's Ley de Comercio Exterior (Foreign Trade Act, LCE), published in the Diario Oficial de la Federación on 27 July 1993 and entering into force 28 July 1993, is the foundational statute governing Mexico's entire external trade regulatory architecture. The LCE establishes the legal authority for the SECOFI/SE-administered antidumping (AD), countervailing duty (CVD), and safeguard investigation regime (Titles V–VII); the TIGIE tariff-schedule and tariff-classification framework; the IMMEX maquila and PROSEC sectoral-promotion programs; rules of origin for USMCA and other preferential trade agreements; and Mexico's export- licensing and strategic-material restriction framework. The LCE has been amended repeatedly through 2021 and remains the overarching parent authority for all Mexican trade-remedy proceedings administered by UPCI (Unidad de Prácticas Comerciales Internacionales) under the Secretaría de Economía.
