On 11 March 2026 USTR Ambassador Jamieson Greer initiated parallel Section 301 investigations into the acts, policies, and practices of 16 economies — China, the European Union, Singapore, Switzerland, Norway, Indonesia, Malaysia, Cambodia, Thailand, Korea, Vietnam, Taiwan, Bangladesh, Mexico, Japan, and India — relating to structural excess capacity and overproduction in manufacturing sectors. The Federal Register notice (FR doc 2026-05214; dockets USTR-2026-0067 and USTR-2026-0068) was published on 17 March 2026. Covered sectors include aluminum, automobiles, batteries, cement, chemicals, electronics, energy goods, glass, machine tools, machinery, paper, plastics, processed food and beverages, robotics, satellites, semiconductors, ships, solar modules, steel, and transportation equipment. Written comments were due by 15 April 2026; USTR held the public hearing beginning 5 May 2026. This is the most sweeping multi-economy Section 301 initiative since the 2018 China investigation and is structurally distinct from the China-only 2024-05-14 §301 tariff hikes and the 2025-07-15 Brazil §301 investigation.

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.
