EU lawmakers in Brussels are worried that the bloc is drifting into the crosshairs of US domestic politics, as the White House launched new trade investigations into EU goods accusing the European Union is “implementing close to zero” of trade commitments.

Next week could prove decisive for the EU–US trade deal struck last summer.

Washington has stepped up pressure on the EU in recent days to implement the agreement cut last summer between the head of the European Commission Ursula von der Leyen and President Donald Trump, tripling tariffs on the EU.

Still, MEPs have kept the implementation process, which also includes investment pledges from the Europeans in the US, frozen, seeking clarity after the Supreme Court of the United States ruled in February that US tariffs imposed in 2025 were illegal.

The fate of the deal remains uncertain after the White House launched new investigations into EU products this week that could lead to tariffs exceeding the 15% ceiling agreed under the pact.

“It is domestic politics and the worst-case scenario has happened: we got involved,” Croatian MEP Željana Zovko, lead negotiator for the European People’s Party, told EU News.

She added: “We were waiting for the Supreme Court’s decision but now of course this administration will do its utmost to do it its own way.”

In the days following the court’s ruling, the US administration has looked for new legal grounds for tariffs and invoked Section 122 to impose fresh duties of 10% on EU goods, on top of the 4.8% tariffs already in place under most-favored nation regime.

The provision allows temporary duties for a maximum of 150 days, after which the US Congress would need to agree an extension. The Supreme Court suggested in its initial ruling that the President had exceeded his powers under emergency grounds.

Next week will be pivotal for the EU-US deal

“Now uncertainty is increasing even more for our businesses,” Zovko said.

Since the court ruling, the EU has sought clarity from Washington on whether the Turnberry agreement signed last year still stands or has been broken.

US officials assured EU trade chief Maroš Šefčovič they would stick to the deal, though they have not detailed how the 10% tariffs after the court ruling will be replaced in the long-term. In return, the US expects the EU to implement the agreement fully and quickly.

US Trade Representative Jamieson Greer raised the temperature on Wednesday, lashing at the Europeans on the basis that “the EU has done approximately zero percent of what they were supposed to do for their trade deal with us.”

“Section 301 will allow the US to differentiate between countries and therefore add pressure to each of them,” he said.

Next week could be pivotal for the EU–US trade deal.

The trip comes as negotiators in the European Parliament must decide whether to resume work on the agreement or postpone the vote once more. A vote is required to cut EU duties on US goods to zero, as foreseen in the Turnberry deal.

But political groups remain divided.

Benifei said the EU needs a clear political signal from Washington that it will stick to the deal, otherwise “there is no way we can vote on the file.”
