The European Union has firmly demanded that the United States adhere to the terms of last year’s EU-U.S. trade agreement, following the Supreme Court of the United States’s decision to strike down a broad swathe of President Donald Trump’s global tariffs and his subsequent announcement of new, temporary levies.
The European Commission, which negotiates trade policy on behalf of the 27 EU member states, emphasized that Washington must provide “full clarity” on its post-ruling steps. After the court invalidated Trump’s global tariffs on Friday, the U.S. president initially announced a 10% across-the-board duty, then raised it to 15% within a day, sparking fresh concerns in Brussels.
“The current situation is not conducive to delivering ‘fair, balanced, and mutually beneficial’ transatlantic trade and investment, as agreed to by both sides,” the Commission said. “A deal is a deal.” This statement marked a stronger response than the Commission’s initial Friday comments, which had merely noted that it was reviewing the court’s outcome and maintaining contact with the U.S. administration.
Trade Deal Protections at Risk
Last year’s EU-U.S. trade deal set a 15% tariff ceiling for most EU goods, excluding certain sector-specific tariffs such as on steel, while allowing zero tariffs on some products including aircraft and spare parts. The EU, in turn, removed duties on many U.S. exports and withdrew threats of retaliatory tariffs.
It remains unclear whether Trump’s new 15% tariffs override the EU-U.S. agreement. If they do, EU exemptions could be jeopardized, and pre-existing “most-favoured-nation” duties might stack on top of the new tariffs something the trade deal had explicitly prevented. The comparative advantage the EU once held under the 15% ceiling now appears diminished, as even countries without a trade agreement face the same rate.
Analysts at Global Trade Alert estimate the EU could be 0.8 percentage points worse off overall, with Italy potentially facing an additional 1.7 points of U.S. tariffs. The Commission stressed that EU products must continue to enjoy the most competitive treatment, warning that unpredictable levies undermine market confidence and disrupt global trade flows.
Diplomatic Engagement
EU Trade Commissioner Maros Sefcovic reportedly discussed the matter directly with U.S. Trade Representative Jamieson Greer and Commerce Secretary Howard Lutnick over the weekend, signaling the bloc’s determination to preserve the integrity of the deal.
The EU’s insistence underscores a growing concern in Brussels that unilateral U.S. tariff measures, even if temporary, could erode the predictability essential for businesses and investors on both sides of the Atlantic. As the U.S. navigates alternative legal pathways for tariffs post-Supreme Court, the EU has made clear that any deviation from the agreed framework will not be accepted.
