Trump Hits UK with 10% Tariffs
The Trump administration has imposed 10% tariffs on all imports from the United Kingdom. The sudden move raises fears of a new global trade war and threatens to significantly strain relations between the two long-standing allies.
This new 10% global tariff follows a February 20th U.S. Supreme Court ruling that invalidated the legal basis for President Trump's previous "Liberation Day" tariffs. The administration then invoked Section 122 of the Trade Act of 1974, a rarely used provision, to impose a temporary 10% levy for up to 150 days without Congressional approval, citing the need to address "fundamental international payments problems." The move creates significant uncertainty for the 40,000 UK companies exporting to the U.S., their largest single-country trading partner. This new blanket tariff negates the preferential 10% rate the UK had previously secured under the May 2025 U.S.-UK Economic Prosperity Deal (EPD), eroding the UK's competitive advantage over other nations that had faced higher rates. Key UK export sectors are particularly exposed. In 2025, mechanical power generators were the UK's top goods export, valued at £43.8 billion, while medicinal and pharmaceutical products stood at £39.9 billion and cars at £31.6 billion. The new tariff situation is especially challenging for the automotive sector, which saw vehicle production fall by 16% in 2025 to 764,715 units, in what the industry has called its "toughest year in a generation." The UK government has stated that "nothing is off the table" regarding a response, leaving open the possibility of retaliatory tariffs while emphasizing a desire for "constructive engagement." Prime Minister Keir Starmer's office has indicated they do not expect the new global tariff to affect the "majority" of the EPD, including specific agreements on steel, pharmaceuticals, and cars. The EPD has been only partially implemented. A key success is a zero-tariff deal for UK pharmaceutical exports, worth over £5 billion annually, which was secured in December 2025 for a minimum of three years. Additionally, the first tariff-free shipment of UK beef under a new 13,000-tonne quota recently arrived in the U.S., a deal projected to be worth up to £70 million a year. For the automotive sector, the EPD had set a 10% tariff for the first 100,000 vehicles, a reduction from a threatened 25-27.5% rate. However, the new, broad-based 10% global tariff effectively levels the playing field, wiping out the advantage the UK had negotiated. U.S. Trade Representative Jamieson Greer has stated that Washington intends to stand by the bilateral deals it has signed. However, the uncertainty has led the British Chambers of Commerce to call for the full implementation of the Economic Prosperity Deal in legal text to provide clarity and stability for businesses on both sides of the Atlantic.
