British Prime Minister Keir Starmer issued an urgent appeal Monday for the swift implementation of a limited trade agreement with the United States, warning that delays could trigger punitive tariffs on British steel and aluminum exports starting July 9.
Speaking to reporters on the sidelines of the Group of Seven summit in Canada, Starmer described the May agreement as providing “a political victory” for his administration while acknowledging that critical implementation details remain unresolved more than a month after the deal’s announcement.
The trade agreement, Trump’s first such deal since his steep tariffs last month roiled stock markets, represents a significant but incomplete victory for British negotiators who have sought to shield key industries from the president’s aggressive tariff regime.
Under the terms negotiated in May, U.S. tariffs on imports from the struggling UK steel industry will fall to zero from 25%, while steel and aluminum tariffs will be scrapped entirely.
However, the deal comes with stringent conditions that have complicated implementation. British steel imports must meet specific supply chain requirements and operate within quotas yet to be finalized between the two governments.
These technical hurdles have created a precarious situation for British exporters, who face the prospect of devastating tariff increases if the implementation timeline slips.
The stakes have risen dramatically since the original agreement. President Trump recently signed a proclamation to increase tariffs to 50% on steel from countries without negotiated exemptions, making Britain’s avoidance of this punitive rate even more critical for its manufacturing sector.
For the automotive industry, the agreement provides partial relief but falls short of complete tariff elimination. US tariffs on cars will be reduced from 27.5% to 10% for 100,000 British-made vehicles per year, offering some protection for British automakers while maintaining pressure on the sector.
The agricultural component of the deal represents a significant concession by Britain. Britain’s 19% tariffs on U.S. ethanol will fall to zero through a 1.4 billion-liter quota that far exceeds U.S. exports to the UK last year, effectively opening the British market to American agricultural products.
Notably absent from the agreement is relief from Trump’s broader 10% universal tariff, which remains in place on most British goods. Trump said he would keep in place his 10% base tariff on most goods coming from the U.K. to the U.S., limiting the deal’s scope and economic impact.
The urgency of Starmer’s appeal reflects broader concerns about the stability of trade relationships under Trump’s unpredictable approach to international commerce. With just weeks remaining before the July 9 deadline, British officials are working frantically to resolve technical issues that could derail months of delicate negotiations and expose British exporters to crushing tariff rates.
The meeting between Starmer and Trump in Canada represents what may be the final opportunity to secure implementation before the deadline, with billions in trade and thousands of jobs hanging in the balance.
WHAT YOU SHOULD KNOW
Britain has just three weeks to finalize implementation of its trade deal with the US or face devastating 50% tariffs on steel and aluminum exports starting July 9. While the May agreement promised to eliminate these tariffs entirely, technical details remain unresolved, leaving British manufacturers in limbo.
Despite being Trump’s first trade partner to secure tariff relief, Britain’s victory remains incomplete and fragile. The deal covers only specific sectors – steel, aluminum, cars, and agriculture—while most British goods still face Trump’s 10% universal tariff.
