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.

On 12 February 2026, Ambassador Jamieson Greer of the Office of the United States Trade Representative oversaw the signing of the US-Taiwan Agreement on Reciprocal Trade (ART) in Washington, DC. The instrument was signed under the auspices of the American Institute in Taiwan (AIT) and the Taipei Economic and Cultural Representative Office in the United States (TECRO). Headline terms: (i) US IEEPA reciprocal-tariff rate on Taiwan reduced from 20% to 15% and Section 232 auto-parts/timber/lumber rate cut from 25% to 15%; (ii) Taiwan eliminates or reduces 99% of its tariff barriers on US goods, most immediately and the remainder phased over three years; (iii) Taiwan side commits ~USD 85bn in directed purchases through 2029 (USD 44.4bn LNG/crude, USD 15.2bn civil aircraft and engines, USD 25.2bn power equipment); (iv) sectoral chapters covering tariffs, non-tariff barriers, digital trade, economic security, and high-tech supply-chain resilience. Operationally linked to the 15 January 2026 AIT-TECRO Memorandum of Understanding on investment, under which Taiwan pledges USD 250bn in direct Taiwanese-enterprise investment in the US plus USD 250bn in Taiwan-government credit guarantees (USD 500bn total) to fund US-side industrial parks/clusters in advanced semiconductors, energy, and AI manufacturing. Entry into force is conditional on Taiwan's Legislative Yuan completing its review.

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 13 November 2025, the United States and the Republic of Korea released a Joint Fact Sheet reaffirming the July 2025 announcement of the Korea Strategic Trade and Investment Deal — the first standalone US-Korea trade-and-investment agreement since the 2012 KORUS FTA. USTR issued the implementing Federal Register notice (90 FR 55964, Notice 2025-21940) on 3 December 2025, effective 4 December 2025, with retroactive HTSUS application to 1 November 2025 for autos and auto parts and to 14 November 2025 for reciprocal-tariff goods, timber, lumber, derivatives, and certain aircraft and aircraft parts. On the US tariff side: (i) the country-specific IEEPA reciprocal tariff on Korean originating goods is set at the higher of the KORUS FTA / MFN rate or 15% (parallel to the Japan and EU framework deals); (ii) the Section 232 tariffs on autos, auto parts, timber, lumber and wood derivatives are reduced to 15% (no incremental duty when the pre-existing KORUS/MFN rate already meets or exceeds 15%); (iii) Korean exports of qualifying goods on the Potential Tariff Adjustments for Aligned Partners (PTAAP) list are exempt from reciprocal tariffs (covering generic pharmaceuticals and unavailable natural resources); (iv) Section 232 pharmaceuticals capped at 15%; semiconductors granted MFN-style "no less favourable" treatment in any future sectoral deal. On the investment side, Korea commits to a USD 350bn package: USD 150bn into US shipbuilding ("Approved Investments") plus USD 200bn into US strategic industries via a separate Strategic Investments MOU, with annual currency-funding cap of USD 20bn. Non-tariff commitments include streamlined US biotech approvals on the Korean side, US meat and cheese market access, fair treatment for US digital services, removal of Korea's 50,000-unit cap on US vehicles meeting FMVSS, and joint WTO support for the moratorium on customs duties on electronic transmissions.

President Trump signed Proclamation 10984 "Adjusting Imports of Medium- and Heavy-Duty Vehicles, Medium- and Heavy-Duty Vehicle Parts, and Buses Into the United States" on 17 October 2025, invoking Section 232 of the Trade Expansion Act of 1962 to impose a 25% ad valorem tariff on imports of Class 3 to Class 8 medium- and heavy-duty trucks (large pick-up trucks, moving trucks, cargo trucks, dump trucks, tractors) and on key MHDV parts, and a 10% ad valorem tariff on buses and other vehicles classified in HTSUS heading 8702. Duties take effect at 12:01 a.m. EDT on 1 November 2025 (Federal Register doc 2025-19639, 90 FR 48451, published 22 October 2025). USMCA-qualifying MHDVs are tariffed only on the value of non-U.S. content; the proclamation also establishes an offset programme for MHDV parts equal to 3.75% of the aggregate value of all MHDVs assembled in the United States from 2025 through 2030, mirroring the Proclamation 10925 light-vehicle offset architecture.

Executive Order 14289 of 29 April 2025 provides that certain overlapping US tariffs should not have a cumulative effect. Where an article is subject to the Section 232 automobile and parts tariffs (Proclamation 10908), it is not subject to the northern- or southern-border duties (EO 14193 / 14194) or to the steel and aluminium Section 232 tariffs; border duties in turn take priority over the metals tariffs, while steel and aluminium tariffs may still stack with each other. The order applies retroactively to entries made on or after 4 March 2025.

President Trump signed Proclamation 10908 "Adjusting Imports of Automobiles and Automobile Parts Into the United States" on 26 March 2025, invoking Section 232 of the Trade Expansion Act of 1962 to impose a 25% ad valorem tariff on imports of finished passenger vehicles and light trucks effective 12:01 a.m. EDT on 3 April 2025, with the duty extended to key automobile parts (engines and engine parts, transmissions and powertrain components, electrical components) effective 12:01 a.m. EDT on 3 May 2025. USMCA-origin automobiles receive an interim deduction equal to the value of US-origin content; USMCA-origin parts that satisfy the agreement's rules of origin are temporarily exempt from the parts duty pending a Commerce-administered process. The proclamation is the first Section 232 instrument applied to finished automobiles in US history and the largest-by-trade-volume Section 232 measure of the second Trump administration, covering roughly USD 460 billion of annual auto and auto-parts imports.
