On 19 March 2026, USTR Ambassador Jamieson Greer and Japan's Ministry of Foreign Affairs, METI, and Ministry of Finance jointly released the "United States-Japan Action Plan for Critical Minerals Supply Chain Resilience" — the operational follow-on to the 27 October 2025 US-Japan Framework. The Action Plan formally commits both governments to develop a plurilateral trade initiative in critical minerals "supported by price floors or other measures", to consult on embedding "border-adjusted price floors" in a binding plurilateral agreement, and to identify specific mining/processing/manufacturing projects in the US, Japan, or third countries for prioritised joint financing. It is the first formal US/Japan trade-policy commitment to administered floor-pricing as an instrument of critical-minerals trade governance, and explicitly invites third countries to join the contemplated plurilateral.

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).

On 27 October 2025, during the Trump-Takaichi Tokyo summit, the United States and Japan announced the "Framework for Securing the Supply of Critical Minerals and Rare Earths through Mining and Processing", signed by President Donald J. Trump and Prime Minister Sanae Takaichi on 28 October 2025. The non-binding framework establishes a US-Japan Critical Minerals Supply Security Rapid Response Group co-led by the US Secretary of Energy and the Japanese METI Minister; commits both governments to provide financial support to selected mining and processing projects within six months via grants, guarantees, loans, equity, offtake arrangements, and insurance — mobilising DFC + EXIM (US side) with JOGMEC + JBIC (Japan side); develops a "mutually complementary stockpiling arrangement" leveraging existing national systems; and schedules a Mining, Minerals and Metals Investment Ministerial within 180 days. The framework was subsequently operationalised through the 19 March 2026 "United States-Japan Action Plan for Critical Minerals Supply Chain Resilience" jointly issued by USTR and METI.

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.

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.

President Trump signed two Presidential Proclamations on 11 February 2025 reinstating a universal 25% ad-valorem tariff on all steel-mill products and raising the aluminum tariff from 10% to 25% on all imports into the United States, effective 12 March 2025. The proclamations revoked every bilateral exclusion and quota arrangement negotiated by the Biden administration with the EU, UK, Japan, Korea, Australia, and others under the 2021-2022 "alternative measures" frameworks, returning all trading partners to the baseline Section 232 rate without product-level or country-level carve-outs.
