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 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 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.

President Trump signed three Executive Orders on 1 February 2025 (EO 14193, 14194, 14195) declaring national emergencies under IEEPA over the cross-border flow of fentanyl + illegal migration, and using that authority to impose new tariffs: 25% on imports from Canada (with a reduced 10% rate on Canadian energy products), 25% on imports from Mexico, and an additional 10% on imports from China (separate from pre-existing Section 301 + Section 232 tariffs). The tariffs took effect 4 February 2025. On 3 February 2025 the administration announced a 30-day pause for both Canada and Mexico following bilateral border-enforcement commitments; the China tariff was not paused. China responded 4 February with retaliatory tariffs of 15% on US LNG/coal/farm equipment and additional measures. The package set the precedent for the broader 2 April 2025 "Liberation Day" reciprocal-tariff regime (filed: 2025-04-02-us-trump-reciprocal-tariff-regime).
