In a notable move, former U.S. President Donald Trump has signed an executive order implementing key elements of a bilateral tariff agreement between the United States and the United Kingdom. The order, signed ahead of his early departure from the G7 Summit in Canada, lowers the tariff on UK vehicle exports to the U.S. from 25% to 10% for up to 100,000 cars annually.

British Prime Minister Sir Keir Starmer hailed the move as a “very important day” for both countries, highlighting it as evidence of renewed economic cooperation across the Atlantic.

The agreement comes after weeks of diplomatic efforts and is the first formal announcement following the U.S. administration’s sweeping tariff hikes earlier this year. The executive order allows for reduced duties on UK-manufactured cars and specific aerospace products, providing a much-needed boost for British exporters.

However, the deal notably excludes steel and aluminium, sectors that had been hit hard by U.S. tariffs and were central to earlier negotiations. When asked directly about potential relief for UK steelmakers, Trump responded vaguely: “We’re gonna let you have that information in a little while.”

The UK government, while welcoming progress on cars and aerospace, said it would continue negotiations to work toward 0% tariffs on core steel exports.

Economic and Industrial Response

The tariff reduction was welcomed by UK automotive manufacturers, who see the move as a lifeline amid supply chain challenges and global competition. Mike Hawes, CEO of the Society of Motor Manufacturers and Traders (SMMT), stated that the deal would allow “many manufacturers to resume deliveries imminently,” and that it restores “confidence among key U.S. buyers.”

In the aerospace sector, select tariffs will also be lifted—details pending. The measure is expected to assist manufacturers involved in transatlantic supply chains and R&D partnerships.

The UK’s Business and Trade Secretary Jonathan Reynolds confirmed that the agreement reflects “fast-paced work between governments to ease pressure on UK exporters.” He also noted ongoing commitments regarding US beef and ethanol quotas, including the UK’s pledge to raise the beef quota from 1,000 to 13,000 metric tons, while maintaining existing food safety standards.

Not a Free Trade Agreement—But Politically Significant

Despite the attention and praise surrounding the pact, it is not a comprehensive free trade agreement (FTA). As U.S. law requires congressional approval for FTAs, Trump’s executive order remains limited in scope.

Critics in the UK, including opposition politicians and business leaders, have described the deal as a “narrow arrangement.” Kemi Badenoch, leader of the Conservative Party, dismissed it as a “tiny tariff deal.”

Still, the optics matter. Trump praised Starmer’s ability to finalize the deal, noting that "others had tried for six years" without success. Starmer, meanwhile, positioned the deal as a “sign of strength” in the UK-US alliance.

Strategic and Market Implications

This tariff reprieve offers tactical relief to UK industries hit hardest by recent global economic uncertainty, while also signaling renewed U.S.-UK economic alignment. For investors and exporters, the automotive provision may restore some balance in bilateral trade flows, while steel and agriculture remain outstanding chapters.

Although limited, the agreement serves as a stepping stone toward broader trade cooperation. It sets a precedent for issue-by-issue negotiations in the absence of a full-scale FTA—something increasingly common in today’s fragmented global trade landscape.

While not a game-changing trade agreement, the Trump–Starmer tariff order marks a symbolically important development in transatlantic trade. For UK manufacturers, it opens the door to greater access and lower costs in the American market. For Washington, it signals a measured but strategic re-engagement with key allies.

As both governments move forward, all eyes will be on whether steel, agriculture, and digital trade follow similar paths—or remain subject to political headwinds.
