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.

South Korea's 13th National Strategic Technology Special Committee (chaired by MSIT) adopted the 2026 Annual Implementation Plan for the First Basic Plan for National Strategic Technology Development (2024–2028), committing KRW 8.6 trillion in 2026 R&D investment — a ~30% YoY increase from KRW 6.5 trillion in 2025 — across 19 NEXT strategic-technology fields encompassing AI, semiconductors, quantum, displays, and secondary batteries, coordinated across 23 ministries. The plan is supplemented by KRW 46.6 trillion in policy finance delivered through Korea Development Bank (KDB), Industrial Bank of Korea (IBK), Korea Credit Guarantee Fund (KCGF), and Korea Technology Finance Corporation (KOTEC), providing the horizontal funding-coordination architecture that operationalises all sector-specific Korean strategic-technology legislative instruments.

On 23 February 2026 the Korea Trade Commission (KTC) at its 461st plenary meeting adopted a final affirmative anti-dumping determination against hot-rolled carbon and alloy steel (HRC) imports from China and Japan, recommending definitive five-year duties of 28.16–33.10% on Chinese-origin HRC and 31.58–33.57% on Japanese-origin HRC to the Ministry of Economy and Finance (MOEF) for implementation via customs notification. The investigation was initiated in March 2024 on petition by Hyundai Steel, following December 2023 injury allegations, with provisional duties imposed in September 2025. KTC simultaneously recommended acceptance of price-undertaking commitments from three Japanese companies (including JFE Steel and Nippon Steel) and six Chinese companies (including Baosteel), allowing those exporters to avoid the definitive duties by maintaining minimum import-price levels; remaining non-participating exporters face the full duty rates under a five-year WTO ADA Article 11 sunset ending 2031.

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).

President Trump signed Executive Order 14382, "Addressing Threats to the United States by the Government of Iran," on 6 February 2026 (effective 12:01 a.m. EST on 7 February 2026; published in the Federal Register on 11 February 2026 as FR doc 2026-02813, 91 FR 6493-6496). Invoking IEEPA, the National Emergencies Act, section 604 of the Trade Act of 1974 and 3 U.S.C. § 301, the order declared a country-specific national emergency with respect to Iran and established a secondary-tariff-authority framework: an additional ad valorem duty (the EO offers "for example, 25 percent" as illustration but sets no binding rate) is authorised on imports of articles produced by any foreign country determined to directly or indirectly purchase, import, or otherwise acquire any goods or services from Iran. Determinations are made by the Secretary of Commerce, with rate recommendations from the Secretary of State in consultation with Treasury, DHS and USTR; the President retains final authority. EO 14382 was structurally modelled on EO 14245 (Venezuelan oil importing countries, 24 March 2025) and EO 14380 (Cuba, 29 January 2026), and was on the list of nine IEEPA-based tariff EOs whose tariff component was vacated by the SCOTUS 6-3 ruling in *Learning Resources, Inc. v. Trump* (20 February 2026). The companion EO 14389 of 20 February 2026 ("Ending Certain Tariff Actions") extinguished the tariff authority for entries on or after 12:00 a.m. ET on 24 February 2026; the underlying Iran national- emergency declaration was preserved. No third-country determination or specific rate was operationalised under EO 14382 prior to vacatur.

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.
