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.

President Trump signed Executive Order "Ending Certain Tariff Actions" on 20 February 2026 (Federal Register doc 2026-03832, published 25 February 2026), terminating the additional ad-valorem duties imposed under nine prior IEEPA-based executive orders. The order followed within hours of the US Supreme Court's 6-3 decision the same day in Learning Resources, Inc. v. Trump, 607 U.S. ___ (2026), holding that the International Emergency Economic Powers Act does not authorize the President to impose tariffs and vacating the Trump 2.0 IEEPA tariff regime. The EO directs CBP to cease collection "as soon as practicable"; CSMS guidance set the collection-end date at 12:00 a.m. eastern on 24 February 2026. The order explicitly preserves all underlying national-emergency declarations and all non-IEEPA trade actions — Section 232 of the Trade Expansion Act, Section 301 of the Trade Act, Section 122 of the Trade Act, and Section 201 — so the Section 232 cascade and the paired Section 122 10% temporary surcharge (effective 24 Feb 2026) remain in force. This is the first SCOTUS-driven repeal of a presidential tariff regime in the modern era and recalibrates the entire post-2024 US tariff architecture by removing IEEPA as a legal pillar.

President Trump signed a Presidential Proclamation on 20 February 2026 invoking Section 122 of the Trade Act of 1974 (19 U.S.C. § 2132) to impose a temporary 10% ad-valorem import surcharge on articles imported into the United States, effective 12:01 a.m. EST on 24 February 2026. The proclamation was issued within hours of the US Supreme Court's 20 February 2026 ruling in Learning Resources, Inc. v. Trump, which held that the International Emergency Economic Powers Act (IEEPA) does not authorize the president to set tariffs and vacated the IEEPA-based reciprocal-tariff regime previously in effect. The Section 122 surcharge is statutorily limited to 150 days (terminates 24 July 2026 absent Congressional extension) and the statute caps any such surcharge at 15% ad valorem. Goods qualifying as USMCA originating from Canada or Mexico are exempt; CAFTA-DR textile/apparel articles meeting specified rules of origin are exempt; and a substantial product-exception list excludes critical minerals, energy products, certain pharmaceuticals, electronics, vehicles, aerospace products, specified agricultural goods, and goods already subject to Section 232 duties (the Section 122 duty does not stack on Section 232).

South Korea's National Assembly passed the "Special Act on Strengthening and Supporting the Competitiveness of the Semiconductor Industry" (반도체산업 경쟁력 강화 및 지원에 관한 특별법) on 29 January 2026 by 199 votes in favour out of 206 members present, after roughly 18 months of inter-party deadlock. The act establishes (i) a Presidential Commission for Enhancing Semiconductor Competitiveness as the central inter-ministerial coordination body, (ii) a statutory five-year master plan with annual implementation plans, (iii) a dedicated semiconductor industry special account ("반도체산업 특별회계") to ring-fence funding for fabs, materials, parts and equipment, and packaging across the full memory + system-LSI + design + manufacturing supply chain, and (iv) authority to designate semiconductor clusters outside the greater Seoul area with relocation incentives. Promulgation by the Cabinet is expected shortly after passage; effectiveness contingent on enforcement-ordinance finalisation, expected Q3 2026. The KRW 2tn anchor envelope of the special account does not begin disbursing until 2027 because companion amendments to the National Finance Act were not enacted in time.

On 14 January 2026 President Trump issued a Presidential Proclamation under Section 232 of the Trade Expansion Act of 1962 imposing a 25% ad valorem tariff on imports of certain advanced computing chips and their derivative products, effective 12:01 a.m. EST on 15 January 2026. The measure adopts findings of the Section 232 investigation initiated 1 April 2025 (Department of Commerce report transmitted 22 December 2025) into semiconductors, semiconductor manufacturing equipment, and derivative products. Coverage is narrowly drawn to high-performance AI accelerators meeting specified technical parameters (publicly characterised as covering devices in the NVIDIA H200 / AMD MI325X performance tier), with broad use-based exemptions for chips going into US data centres, US R&D, US repairs, and other uses deemed to strengthen domestic supply chains.

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).

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.

The US Bureau of Industry and Security (BIS) amended the Export Administration Regulations to remove three foreign-owned semiconductor fabs operating in China — Intel Semiconductor (Dalian) Ltd, Samsung China Semiconductor Co. Ltd, and SK hynix Semiconductor (China) Ltd — from the Validated End-User (VEU) Authorizations list (15 CFR Part 748). BIS framed the VEU program as a "loophole" that previously allowed these fabs to receive most US-origin chipmaking equipment, software and technology license-free, a privilege no US-owned fab in China ever had. After the effective date, every restricted shipment to these fabs will require an individual export license, reviewed case-by-case under the existing 2022/2023 advanced- computing controls. The rule is published as Federal Register document 2025-16735 (90 FR 42321), Docket BIS-2025-0555, RIN 0694-AK32.

President Trump signed Executive Order 14257 on 2 April 2025 declaring a national emergency over US trade deficits and imposing a baseline 10% ad-valorem tariff on imports from nearly all trading partners effective 5 April, with higher country-specific "reciprocal" rates effective 9 April. The rate schedule was constructed from a formula tied to bilateral goods-trade deficits and ranged from 10% (UK, Singapore, Brazil, Australia, others) through 20% (EU), 24% (Japan), 25% (Korea), 32% (Taiwan, Indonesia, Switzerland), 34% (China, later raised to 84% then 125% during the April escalation), 46% (Vietnam), 49% (Cambodia). Multiple subsequent EOs paused the country-specific rates for 90 days for non-China destinations on 9 April while keeping the 10% baseline, pending bilateral negotiations.

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.

The US Bureau of Industry and Security issued its largest single export-control package targeting China's semiconductor industry on 2 December 2024, with three layered measures (final rules published in the Federal Register 5 December 2024). First, controls on high-bandwidth memory (HBM) above set performance thresholds — blocking the memory architecture that is foundational to AI training. Second, additions of 24 semiconductor manufacturing equipment item types to the Commerce Control List, covering deposition, etch, ion- implant, advanced packaging, and metrology categories. Third, Entity List designations for 140+ entities, the bulk Chinese semiconductor companies + equipment makers + investment vehicles, including major Chinese fab tooling firms. The package triggered MOFCOM's same-day-following retaliation (filed: 2024-12-03-china-mofcom-ge-ga-sb-export-ban-us).

South Korea's National Assembly enacted the Special Act on National Resource Security (국가자원안보 특별법, Act No. 20114) on 6 February 2024, with the law taking effect on 7 February 2025 alongside its Enforcement Decree (adopted 14 January 2025). The statute is the first horizontal Korean resource-security framework, covering oil, natural gas, coal, hydrogen and government-designated critical minerals. It establishes a four-tier crisis-alert system (관심·주의·경계·심각 / Attention · Caution · Alert · Serious) under a MOTIE-led inter-ministerial committee, authorises emergency-import measures, mandatory stockpile build/release orders, supply-chain disclosure obligations and price-control powers during designated crises, and requires a five-year basic resource-security plan. The Act operationalises through Korea National Oil Corp., Korea Gas Corp. and the post-2024 KORES successor agency (KOMIR), and creates a statutory designation framework for "selected critical materials" (선도사업자) and "core resource-security companies" eligible for fiscal and financial support.

The US Bureau of Industry and Security issued an interim final rule on 17 October 2023 that substantially expanded the advanced-computing and semiconductor manufacturing controls first imposed in October 2022. The rule closed the performance-threshold workaround that NVIDIA had used to ship China-specific A800/H800 GPUs, replacing it with a "performance density" metric and adding a new "Notified Advanced Computing" licence category. It expanded controls on chipmaking equipment (additional ECCNs covering deposition, etch, metrology), pulled 21 additional countries (mostly Middle East / Central Asia) into a regional licensing scheme to prevent transshipment, and added 13 Chinese entities to the Entity List including AI-chip designers.

China's Ministry of Commerce and General Administration of Customs jointly announced an export licensing regime covering eight gallium-related items (including gallium metal, gallium arsenide, gallium nitride wafers and ingots) and six germanium- related items (including germanium metal, germanium oxide, germanium tetrachloride). Effective 1 August 2023, exporters must obtain a dual-use-item licence from MOFCOM citing the end-user and end-use, with licences granted at MOFCOM's discretion. The measure was framed as protecting national security and interests, though the timing immediately followed the Dutch ASML DUV controls and US chip-equipment escalations.

The Korean National Assembly passed an amendment to the Restriction of Special Taxation Act (조세특례제한법, Act No. 19234) on 30 March 2023, promulgated 31 March 2023 and retroactive to 1 January 2023. The amendment enhanced the investment tax credit (ITC) for "national strategic technology" (국가전략기술) semiconductor facility investment: large companies receive a 15% ITC on qualifying capital expenditure (up from 8% in the December 2022 base version); small and medium enterprises receive 25%. An additional temporary 10% incremental credit applies for annual investment exceeding the prior 3-year average (effective 2023-2025). Internationally termed the "K-Chips Act," the measure directly mirrors the US CHIPS Act's 25% advanced- manufacturing investment tax credit. Principal beneficiaries are Samsung Electronics (Samsung Foundry plus DRAM/NAND capex of KRW 20-30 trillion per year) and SK Hynix (memory fabs at Icheon and Cheongju, HBM expansion). In the same session the National Assembly passed companion legislation on secondary-battery (EV) investment with equivalent credit rates. The Korean government projected annual tax savings for the semiconductor sector of approximately KRW 1-2 trillion.

The US Bureau of Industry and Security imposed broad new controls on the export of advanced computing chips, chipmaking equipment, and US-person services supporting Chinese semiconductor fabrication. The October 7 2022 rule blocked supply of GPUs above set performance thresholds (initially 600 GB/s interconnect / 4800 TOPS) to China and added end-use restrictions on manufacturing tools used in advanced (≤14/16 nm logic, ≤18 nm DRAM, ≤128-layer NAND) facilities, with a foreign direct product rule extending coverage globally.
