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 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.

Taiwan's Ministry of Economic Affairs International Trade Administration (MOEA-ITA) amended the Strategic High-Tech Commodities (SHTC) export-control Entity List on 10 June 2025 (announced 15 June 2025) under Article 13 of the Trade Act, adding 601 new entities — including Huawei Technologies Co. Ltd. and Semiconductor Manufacturing International Corp. (SMIC) plus 599 additional entities domiciled in China, Russia, Iran, Pakistan and Myanmar. Taiwanese exporters (TSMC, UMC, ASE, KYEC and downstream suppliers) must obtain pre-export government licences for direct or third-party shipments of any SHTC-listed item to the listed entities; the action expands Taiwan's total entity-list population to ~10,844 entities. Two follow-on amendments tightened the regime further: a +279-entity expansion on 18 September 2025 and an 18-item commodity-list expansion on 18 November 2025 covering advanced 3D printers, semiconductor manufacturing equipment, electron microscopes and quantum-computing hardware.

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.

The US Bureau of Industry and Security issued its largest single export-control package targeting China's semiconductor industry on 2 December 2024, with three layered measures (final rules published in the Federal Register 5 December 2024). First, controls on high-bandwidth memory (HBM) above set performance thresholds — blocking the memory architecture that is foundational to AI training. Second, additions of 24 semiconductor manufacturing equipment item types to the Commerce Control List, covering deposition, etch, ion- implant, advanced packaging, and metrology categories. Third, Entity List designations for 140+ entities, the bulk Chinese semiconductor companies + equipment makers + investment vehicles, including major Chinese fab tooling firms. The package triggered MOFCOM's same-day-following retaliation (filed: 2024-12-03-china-mofcom-ge-ga-sb-export-ban-us).

The US Bureau of Industry and Security issued an interim final rule on 17 October 2023 that substantially expanded the advanced-computing and semiconductor manufacturing controls first imposed in October 2022. The rule closed the performance-threshold workaround that NVIDIA had used to ship China-specific A800/H800 GPUs, replacing it with a "performance density" metric and adding a new "Notified Advanced Computing" licence category. It expanded controls on chipmaking equipment (additional ECCNs covering deposition, etch, metrology), pulled 21 additional countries (mostly Middle East / Central Asia) into a regional licensing scheme to prevent transshipment, and added 13 Chinese entities to the Entity List including AI-chip designers.

The US Bureau of Industry and Security imposed broad new controls on the export of advanced computing chips, chipmaking equipment, and US-person services supporting Chinese semiconductor fabrication. The October 7 2022 rule blocked supply of GPUs above set performance thresholds (initially 600 GB/s interconnect / 4800 TOPS) to China and added end-use restrictions on manufacturing tools used in advanced (≤14/16 nm logic, ≤18 nm DRAM, ≤128-layer NAND) facilities, with a foreign direct product rule extending coverage globally.
