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.

President Trump signed Executive Order 14345 on 4 September 2025, implementing the July 2025 US-Japan trade agreement by setting a 15% baseline ad-valorem tariff on nearly all Japanese goods — raising any Column 1 (MFN) duty rate below 15% up to that floor, including on agricultural lines such as cereals, vegetables, and fruits and nuts. The modification applies retroactively to Japanese products entered for consumption on or after 12:01 a.m. EDT, 7 August 2025, and supersedes the higher 24% country-specific reciprocal rate Japan faced under the April 2025 "Liberation Day" schedule. Aerospace products are exempted entirely, autos/auto parts receive the same 15% treatment (down from a separate 25% Section 232 rate), and Japan committed to $550bn in US investment and $8bn/year in additional US agricultural purchases (rice, corn, soybeans, fertilizer, bioethanol) as consideration.

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.

Governor in Council made the China Surtax Order (2024) (SOR/2024-187) on 20 September 2024 under subsection 53(2) of the Customs Tariff, imposing a 100% surtax on Chinese-origin electric and certain hybrid passenger automobiles, trucks, buses, and delivery vans (HS chapters 87.02–87.04) effective 1 October 2024. An amending order (SOR/2024-202, registered 11 October 2024) extended a 25% surtax to a defined list of Chinese-origin steel and aluminum products (HS chapters 72 and 76) effective 22 October 2024. Canada framed the measures as a response to Chinese state-led overcapacity, non-market subsidies, and weak labour/environment standards, and explicitly aligned them with the US Section 301 hike and the EU's parallel anti-subsidy duties on Chinese EVs.

The Trade Expansion Act of 1962 (Pub. L. 87-794, 76 Stat. 872), signed into law by President Kennedy on 11 October 1962 and codified at 19 U.S.C. §§ 1801–1991, is the foundational US statute granting the executive branch broad authority to negotiate tariff reductions and, critically via Section 232 (19 U.S.C. § 1862), to adjust imports of any article found by the Secretary of Commerce to threaten to impair national security. Section 232 empowers the President — on receipt of a Commerce Department affirmative national-security finding — to impose tariffs, quantitative restrictions, or other import-adjustment measures without congressional approval or WTO-required safeguard procedures. From 1962 to the Trump Administration's 2018–2026 wave of Section 232 Proclamations, the authority was invoked primarily for petroleum and machine-tool imports; since 2018 it has become the legal vehicle for national-security tariffs on steel, aluminum, automobiles, copper, timber, critical minerals, semiconductors, and pharmaceuticals, with 19+ IPTM-filed implementing instruments citing Pub. L. 87-794 / 19 U.S.C. § 1862 as their statutory parent.
