Britain is facing a major trade setback after US President Donald Trump imposed sweeping global tariffs on steel and aluminium imports, a move that has drawn sharp reactions from trade officials and industry leaders.
The UK, which had hoped to avoid such measures, now finds itself caught in the crossfire of a US-EU trade dispute.
The tariffs, which came into effect overnight, introduce a 25% duty on steel and aluminium entering the United States. The European Union has already announced it will introduce counter-measures targeting US goods, but Britain has so far resisted immediate retaliatory action. Business Secretary Jonathan Reynolds, however, warned that the UK “won’t hesitate to respond in the national interest.”
The decision is a significant blow to Prime Minister Keir Starmer and the newly appointed UK ambassador to the US, Lord Peter Mandelson, both of whom had worked to prevent the tariffs.
Last month, following their White House meeting, President Trump had praised Starmer for “negotiating hard” on the issue, while Mandelson made securing an exemption one of his top diplomatic priorities. Despite their efforts, Britain has been drawn into what is rapidly escalating into a global trade conflict.
As a non-member of the European Union, Britain now finds itself outside of the two dominant trading blocs, facing the possibility of further tariffs that could impact its already delicate trade relationships. Brexit campaigners had argued that leaving the EU would provide greater protection from US trade policies, but the latest development has placed UK steel manufacturers in a vulnerable position.
Reynolds described the tariffs as disappointing but emphasized the government’s focus on a “pragmatic approach.” He confirmed that ministers are negotiating a broader economic agreement with Washington to eliminate the additional duties.
“This government is working with affected companies today, and I back the industry’s application to the Trade Remedies Authority to investigate what further steps might be necessary to protect UK producers.”

The European Commission, however, is taking a more aggressive stance, with Brussels confirming that counter-measures affecting €26 billion (£22bn) worth of exports to the US will be implemented in April to “defend European interests.” The contrasting responses have sparked debate over whether the UK should align itself with the EU in trade disputes or forge its own independent strategy.
Growing Pressure on UK to Retaliate
Trade officials and industry leaders are urging the government to strengthen the UK’s trade defences. Gareth Stace, Director-General of UK Steel, called the Trump administration’s move “hugely disappointing” and demanded stronger protections for the sector.
“These tariffs couldn’t come at a worse time for the UK steel industry, as we battle with high energy costs and subdued demand at home, against an oversupplied and increasingly protectionist global landscape.”

Stace also warned that the European Union’s response could further worsen the situation, saying, “What’s more, the EU is also pushing ahead with trade-restrictive action that will amplify the impact of US tariffs.” He urged the government to not only continue lobbying for exemptions but also to take “decisive action” to strengthen trade policies.
Sharon Graham, General Secretary of the Unite union, echoed these concerns, calling for immediate government intervention.
“Our government must act decisively to protect the steel industry and its workers following the announcement of US tariffs. This is a matter of national security.”

She further suggested that steel should be “immediately designated as critical national infrastructure to properly protect it.”
Despite the calls for strong counter-measures, some trade analysts believe that a diplomatic approach remains the best path forward. Naomi Smith, Chief Executive of Best for Britain, urged the UK to deepen ties with European allies to “shield the UK and Europe from Trump’s tariffs” and drive “significant economic growth across Britain.”
As Britain navigates this latest trade challenge, the coming weeks will be critical in determining the long-term impact of Trump’s tariffs on the UK economy.
