On June 2, 2026, USTR published final actionability findings in 60 parallel Section 301(b) investigations — the largest simultaneous Section 301 action in US history — determining that all 60 economies maintain unreasonable acts, policies, or practices by failing to impose or effectively enforce a prohibition on imports produced with forced labor. USTR proposed two additional duty rates: 10% on the 14 economies with partial forced-labor regimes (Canada, Ecuador, EU, Indonesia, Mexico, Pakistan, Argentina, Bangladesh, Cambodia, El Salvador, Guatemala, Malaysia, Taiwan, UK) and 12.5% on the remaining 46 economies. Tariff rates remain proposed pending a July 7, 2026 public hearing and subsequent finalization; the actionability determination is final.

On 2 April 2026 President Trump issued a Presidential Proclamation under Section 232 of the Trade Expansion Act of 1962 ("Adjusting Imports of Pharmaceuticals and Pharmaceutical Ingredients into the United States") imposing a 100% ad valorem tariff on imports of patented pharmaceutical products listed in the FDA Orange Book and Purple Book, together with the active pharmaceutical ingredients (APIs) and key starting materials used to make them. The base rate takes effect at 12:01 a.m. EDT on 31 July 2026 for the 17 manufacturers identified in Annex III, and on 29 September 2026 for all other companies. The proclamation adopts findings of the Section 232 investigation initiated by the Department of Commerce on 14 April 2025 into pharmaceuticals and APIs as a national- security supply-chain risk. The instrument is structured around a multi-tier rate ladder rather than a flat tariff: concessionary 15% rates for EU/Japan/South Korea/Switzerland/Liechtenstein under reciprocal-deal tracks, 10% for the UK with a pathway to 0% under the pending UK pharmaceutical agreement, a "+20%" surcharge for companies operating under a Commerce-approved onshoring plan (until 2 April 2030), and a 0% pathway for companies that combine an approved onshoring plan with an MFN-pricing agreement with HHS (until 20 January 2029). Generics, biosimilars and their ingredients, orphan drugs, nuclear medicines, plasma-derived therapies, fertility treatments, and cell/gene therapies are carved out.

The UK's steel safeguard measure (25% out-of-quota duty) expired 30 June 2026 and was replaced from 1 July 2026 by a new tariff-rate-quota trade measure, announced by the Department for Business and Trade on 19 March 2026. The new measure cuts overall duty-free quota volumes by 51% versus the expired safeguard and raises the out-of-quota tariff to 50% by value, applied across 20 steel product categories. Ukraine-origin steel is exempt; two non-alloy wire commodity codes drop to 0% duty from 1 October 2026.

The UK Finance Act 2026, which received Royal Assent on 18 March 2026, establishes the primary statutory framework for the United Kingdom Carbon Border Adjustment Mechanism (UK CBAM), granting HM Revenue & Customs the assessment, collection, and enforcement powers needed to apply a carbon-content levy on imports of aluminium, cement, fertilisers, hydrogen, and iron & steel from 1 January 2027. Two tranches of draft secondary legislation (the CBAM Regulations 2026 covering administration, rate calculation/carbon-price relief, emissions and verification, and transitory provisions) were published for technical consultation on 10 February 2026 (closing 24 March 2026) and again in Spring 2026 (closing 21 May 2026). The mechanism imposes a UK ETS-linked benchmark price on the embedded carbon of in-scope imports, with a credit for verified third-country carbon prices already paid, and — unlike the EU CBAM — has no transitional reporting phase and a narrower initial sectoral scope (no electricity).

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).

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.

The UK Trade Remedies Authority initiated antidumping investigation AD0071 on 6 June 2025 into hot-rolled steel plate (flat-rolled products of iron or non-alloy steel, 600mm+ width, hot-rolled, not clad/plated/coated, not in coils, 4.75mm+ thickness) originating in South Korea, following an application by UK producer Spartan UK Ltd. The TRA found South Korean imports grew from ~14,000 tonnes in 2021 to over 40,000 tonnes the following year. In April 2026 the TRA published its Statement of Essential Facts proposing duties of 7.04%-22.27% on narrow plates (600mm-2500mm width) — its preferred option — or 5.98%-24.28% if applied to the full scope, after an Economic Interest Test found full-scope duties would harm UK downstream sectors (renewable energy, shipbuilding, defence) reliant on wider-plate imports.

On 8 May 2025, President Trump and UK Prime Minister Starmer announced the General Terms of the US-UK Economic Prosperity Deal (EPD), the first bilateral framework arrangement of the second Trump administration and the template instrument for subsequent US bilateral framework deals (US-Japan, US-Indonesia, US-Argentina, US-Korea, US-EU). The framework was implemented on 23 June 2025 via Executive Order 14309 (Federal Register doc 2025-11473). Key US concessions: a 100,000-vehicle annual TRQ for UK autos at a 10% combined rate (7.5% + 2.5% MFN, vs. 27.5% Section 232 default); aerospace tariff reduction back to MFN rates; authority delegated to Commerce/USTR to establish UK-only TRQs for steel and aluminum (in lieu of the 50% Section 232 global rate). Key UK concessions: 13,000 mt duty-free beef quota (with 20% tariff removal on the existing 1,000 mt WTO quota); 1.4 billion litre duty-free ethanol quota; commitment to negotiate non-tariff barrier reductions and supply-chain security alignment. The 10% IEEPA "reciprocal" baseline tariff on most other UK goods is preserved by the EPD.

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.
