Latest US trade policy announcements

EU-US trade deal

On 21 August, the EU and US announced the "Framework to the Agreement on Reciprocal, Fair, and Balanced Trade." Key areas of relevance include:

  • Tariff elimination: The EU plans to eliminate tariffs on all US industrial goods and offer preferential market access for US seafood and agricultural products, including various nuts, dairy, fruits, vegetables and meats. In return, the US will apply either Most Favored Nation (MFN) tariffs or 15% tariffs on EU goods. From 1 September 2025, the US will only apply MFN tariffs to specific EU products, including natural resources, aircraft and pharmaceuticals.
  • Section 232 Trade Expansion Act 1962 treatment: The US aims to ensure that the combined tariff rate on EU-originating goods in pharmaceuticals, semiconductors and lumber does not exceed 15%. Future reductions on EU automobiles will depend on the EU's legislative proposals.
  • Non-tariff barriers: Both parties commit to reducing or eliminating non-tariff barriers and mutually recognizing each other's standards, facilitating conformity assessments across additional industrial sectors.
  • Rules of origin: Both parties commit to negotiating favorable rules of origin to ensure that the benefits of the Agreement primarily accrue to the US and EU.
  • Sustainability initiatives: The US concerns regarding the EU's Carbon Border Adjustment Mechanism (CBAM) for US small and medium-sized businesses are acknowledged, with the EU promising to introduce further flexibilities. The EU also commits to ensuring that the Corporate Sustainability Due Diligence Directive (CSDDD) and the Corporate Sustainability Reporting Directive (CSRD) do not impose undue restrictions on transatlantic trade.
  • Energy and technology security: The EU and US will collaborate on securing reliable energy supplies, with the EU intending to procure significant amounts of US-originating Liquid Natural Gas (LNG), oil and nuclear energy products. Additionally, the EU plans to purchase US-originating Artificial Intelligence (AI) chips for its computing centers and work with the US to maintain technology security requirements.
  • Investment and economic security: The EU is expected to invest an additional US$600b in strategic sectors in the US by 2028, reflecting a strong commitment to the transatlantic partnership.
  • Digital trade: Both parties will address unjustified digital trade barriers and will not impose customs duties on electronic transmissions. The EU intends to consult with the US on the digitalization of trade procedures and the proposed EU Customs Reform legislation.

Section 232 Trade Expansion Act 1962 investigation into wind turbines

On 13 August, the US Secretary of Commerce initiated an investigation to evaluate the impact of imports of wind turbines and their components on national security of the US.

Key focus areas of the investigation include:

  • Demand assessment: Current and projected demand for wind turbines in the US
  • Domestic production: The ability of US manufacturers to meet this demand
  • Foreign supply chains: The role of foreign suppliers in fulfilling US needs and the risks associated with reliance on a limited number of sources
  • Impact of subsidies: The effects of foreign government subsidies and unfair trade practices on the US wind turbine industry
  • Economic implications: The consequences of artificially low prices due to foreign practices and the potential for export restrictions by foreign nations
  • Domestic capacity: The feasibility of increasing US production capacity to reduce import reliance
  • Trade policies: The impact of current trade policies on domestic production and the need for additional protective measures

Stakeholders with a vested interest in the investigation can submit comments on the investigation, or provide broader industry-specific submissions regarding the investigation.

This investigation adds to the eight Section 232 sectors under review by the US Department of Commerce's Bureau of Industry and Security, which include key sectors such as pharmaceuticals, critical minerals and semiconductors.

Existing tariffs associated with Section 232 are already in place for automotives and associated parts, steel and aluminum and associated derivatives, and copper.

Federal Circuit ruling on Trump Administration's IEEPA tariffs

On 29 August, the US Court of Appeals for the Federal Circuit ruled that President Trump had exceeded his authority in imposing certain tariffs under IEEPA.

The court, in a 7-4 decision, determined that IEEPA does not authorize the universal tariffs introduced by Trump, nor the fentanyl tariffs on China, Canada and Mexico.

The majority expressed skepticism regarding the broader application of tariffs under IEEPA, highlighting that tariffs and duties are not explicitly mentioned in the law. They noted that when considering the broader application of tariffs, a President must adhere to various procedural and substantive requirements outlined in other tariff statutes.

The Trump Administration appealed and, on 9 September 2025, the US Supreme Court granted certiorari and a motion to expedite oral arguments. Oral arguments are now scheduled for 5 November 2025. (For background, see EY Global Tax Alert, US Supreme Court will hear oral arguments in tariff case in early November 2025; opening briefs due soon, dated 10 September 2025.)

Extension of Section 301 China product exclusions

On 29 August, the United States Trade Representative (USTR) extended the product-specific exclusions and 14 exclusions covering certain manufacturing equipment subject to Section 301 duties until 29 November 2025.

Importers, customs brokers and filers are provided with instructions on how to submit entries to Customs and Border Protection (CBP) that include the granted exclusions from Section 301 duties. Goods entered for consumption or withdrawn from a warehouse for consumption between 1 September 2025 and 29 November 2025, are required to file under HTSUS 9903.88.69 or 9903.88.70 to claim the applicable exclusions. (See EY Global Tax Alert, US-Japan Agreement updated and public comment period open for Section 301 extensions, dated 18 September 2025.)

Trump Administration announces withdrawal of WTO funding

On 29 August, the Trump administration released a statement that will cancel US$29m worth of WTO funding.

The US was the largest contributor to the WTO in 2024, making up 11.3% of the total contribution worth £21.5m/US$28.8m.

Modifying tariffs and procedures for trade and security agreements

On 5 September, the Trump Administration issued an Executive Order (EO) updating Annex II in EO 14257 of 2 April 2025 to include additional goods exempt from tariff exposure under the April EO. This update applies to goods that have entered the US for consumption or have been withdrawn from warehouses for consumption since 8 September 2025.

The Annex II updates ensure that products that cannot be cultivated, mined or produced in sufficient quantities in the US remain accessible to meet domestic demand. For example, unprocessed critical minerals, aircraft and aircraft parts, as well as non-patented pharmaceuticals have been added to the updated Annex II.

The 5 September EO outlines adjustments to the implementation of future tariff rates. For example, following the conclusion of any framework agreement with trading partners, including past agreements with US trading partners such as the UK, EU, Japan and Korea, the authority to determine implementation will now rest with the US Secretary of Commerce and the US Trade Representative. This shift indicates that discussions regarding product exemptions or the adequacy of a trading partner's compliance frameworks will no longer be governed solely by EOs, but rather through detailed revisions to the Customs Code.

The September EO also notes that the Administration's willingness to reduce country-specific tariffs to 0%, or modify Section 232 tariffs will depend on several factors, including the scope and economic value of a trading partner's commitments to the US, the national interests of the US and the broader implications of the national emergency declared in EO 14257 on 2 April.

Businesses that have pre-filed import entries scheduled after the 8 September effective date should amend entries to reflect the correct tariff within 10 days of release from Customs and Border Protection (CBP) custody. (See EY Global Tax Alert, US Executive Order modifies scope of certain tariffs and establishes procedures for implementing trade and security agreements, dated 15 September 2025.)

US-Japan framework agreement details

On 15 September, US Customs and Border Protection (CBP) announced customs guidance for Japanese-originating imports into the US, following the release of an EO outlining the implementation details of the framework agreement struck between the US and Japan on 22 July.

The US will apply a baseline 15% tariff on nearly all imports from Japan. The specific tariff rates will be determined based on the product's current ad valorem (or ad-valorem equivalent) rate under the Harmonized Tariff Schedule of the United States (HTSUS):

  • For Japanese-originating imports with an HTSUS rate less than 15%, the tariff rate will be set at 15%.
  • For products with an HTSUS rate of 15% or higher, the tariff will be zero.

The tariff adjustment will apply retroactively to all Japanese-originating products that entered the US for consumption or were withdrawn from a warehouse for consumption on or after 12:01 a.m. Eastern Time on 7 August 2025 (for Japanese-originating imports of automobiles and automobile parts, and civil aircraft, the tariff application outlined above will apply on 16 September).

Businesses with consistent trade flows between Japan and the US will likely discover an overpayment of duties. This issue has been recognized by CBP, which will make refunds available through the standard refund process.

Latest UK trade policy announcements

Update on new SPS agreement for UK food and drink exporters

The SPS agreement between the UK and the EU, which was signed in May 2025, is expected to increase exports of food and drink from UK businesses, with an estimated annual contribution of £5.1b to the UK economy. This agreement aims to address agrifood trade with the EU, the UK's largest trading partner.

The agreement is part of the UK government's "Plan for Change" and is designed to support small food and drink exporters across the UK by reducing costs and streamlining processes associated with exporting products such as dairy, fish, eggs and red meat, thus contributing to export growth, job creation and an enhanced supply chain.

Latest EU trade policy developments

European Commission calls for stronger customs controls and cooperation on product compliance

On 28 August, the European Commission reported that products imported into the EU are not always compliant with EU regulations on safety, security or environmental standards. As a result, increased cooperation between customs and market surveillance authorities is needed to prevent noncompliant products from entering the EU Single Market. The EU Customs Reform currently under negotiation between the European Council and the European Parliament is expected to contribute to improved customs controls and risk management.

The Commission's document — "E-commerce communication: A comprehensive EU toolbox for safe and sustainable e-commerce" — addresses safety concerns surrounding e-commerce for citizens. The EU Customs Reform will introduce a new EU Customs Authority and Data Hub for more effective risk management and cooperation between customs authorities and other authorities, with the aim of making customs controls more effective, efficient and transparent.

EU Carbon Border Adjustment Mechanism: further calls for evidence

On 29 August, the Commission announced three consultations calling for stakeholders to comment on the rules on the methodology for calculating emissions embedded in CBAM goods.

Feedback is open until 25 September 2025 for the following:

European Commission's Single Market and Customs Programme

On 3 September, the European Commission adopted a second package of its seven sectoral proposals, which together establish the framework for the long-term EU budget for 2028–2034.

The Single Market and Customs Programme sector proposal aims to reduce cross-border and cross-country barriers while facilitating cooperation among national administrations.

The European Commission has proposed €6.2b for the Programme, which will merge four EU funding streams — Single Market, Customs Union, taxation cooperation and anti-fraud measures — and pool funding to cut red tape, remove barriers and boost cooperation between national administrations.

Once fully operational, the Programme will work to minimize the administrative burdens associated with customs, taxation and anti-fraud measures — supporting more efficient, agile and future-proof customs procedures that ensure better protection from unsafe goods and unfair market competition.

Latest trade remedy developments

UK Trade Remedies Authority presents new anti-dumping measure on Chinese biodiesel

On 22 August, the UK Trade Remedies Authority (TRA) proposed the following ad-valorem anti-dumping duties on Chinese biodiesel imports:

  • 15.68% for the Zhuoyue Group and non-sampled cooperating exporters
  • 54.64% for all other exporters

The TRA claims that Chinese biodiesel was being dumped in the UK at low prices, negatively impacting UK producers. Alongside biodiesel fuels, other products that were investigated include fatty-acid mono-alkyl esters (FAME) and hydrotreated vegetable oils (HVO), which is used as road transport fuel in the UK.

Currently, there is an online consultation inviting stakeholders to comment or submit additional evidence, which is available until 22 September 2025.

Latest global trade policy developments

Mexico increases tariffs on Chinese imports

On 10 September, the Mexican government announced an increase in tariffs from 20% to 50% on cars of Chinese origin, a decision expected to affect US$52b in imports. The announcement also included a proposed 35% tariff on Chinese origin steel, toys and motorcycles, as well as a 10 - 50% tariff on textiles.

As of 2024, China is Mexico's second largest import partner, following the United States, with total imports amounting to US$119.37m, and representing 20.69% of Mexico's total imports.
