Tariffs Unleashed: Brexit Exporters Caught in US Trade Policy Quagmire

The United Kingdom‘s export sector faces escalating challenges as U.S. President Donald J. Trump‘s fluctuating tariff policy creates unprecedented uncertainty. Following the Supreme Court’s invalidation of his ‘Liberation Day‘ tariffs in late February 2026, the administration imposed a temporary 10% tariff on imports, with a potential 15% rate looming. This policy shift has disrupted global trade dynamics, prompting UK businesses to reassess their strategies and seek alternative markets.

The 10% tariff rate, which took effect on February 24, 2026, represents a significant increase compared to the 10% agreed under the UK-US trade deal finalized in May 2025. This change has raised costs for UK exporters, with the British Chambers of Commerce (BCC) estimating that the tariff increase could raise export costs by £2 billion to £3 billion over a 12-month period. The BCC‘s William Bain warned that the uncertainty surrounding future tariff rates is making it difficult for companies to plan for the next 12-18 months, with many struggling to predict pricing and margins for goods in production.

UK exporters in key sectors such as food and drink, clothing and footwear, and electrical and industrial goods are particularly vulnerable. These industries rely heavily on U.S. markets, and the tariff fluctuations have created a ‘never-ending barrage of on-off import tariff announcements‘ that have fueled anxiety among businesses. Lucy Granger of the East Midlands Chamber noted that the cost of exporting to the U.S. has reached an ‘almost unbearable level‘, prompting calls for immediate government intervention.

The UK government has acknowledged the challenges, with Prime Minister Keir Starmer‘s spokesperson stating that discussions are ongoing to ensure the UK-US trade deal is honored. The Department for Business and Trade confirmed the 10% tariff rate, though it remains unclear if the 15% rate will apply to UK goods. The BCC has proposed a six-point plan, including increasing UK Export Finance capacity to £100 billion and reviewing the UK’s global tariff policies to ease import costs for manufacturers.

The European Union has paused ratification of its trade deal with the U.S., citing concerns that Trump‘s tariff policy breaches the terms of the transatlantic agreement. European Parliament’s international trade committee chief Bernd Lange emphasized the need for ‘clarity and legal certainty‘ before further steps are taken. Meanwhile, the UK is seeking to strengthen trade ties with the EU and Indo-Pacific regions, as businesses look for more stable trade partnerships.

Under Section 122 of the 1974 Trade Act, the current tariffs are authorized for 150 days, after which Congressional approval would be required for any extension. Duncan Edwards of BritishAmerican Business warned that the lack of clarity on future policy could lead to continued uncertainty, with Congress’s narrow margins making it unlikely to provide definitive answers.

The tariff volatility is affecting not only individual businesses but also the broader UK economy. With many companies already adjusting their strategies to mitigate risks, the long-term impact could include reduced export volumes, lower profit margins, and potential job losses. The UK’s trade deficit with the U.S. could widen, further straining the economy.

As the UK navigates this complex trade landscape, the government and industry leaders are under pressure to find solutions that balance economic interests with the need for stability. The ongoing tariff disputes highlight the fragility of international trade relations and the importance of clear, predictable policies for global commerce.
