EU Demands U.S. Honor Trade Deal After Tariff Ruling

The European Union has called on Washington to provide “full clarity” on its trade policy after the U.S. Supreme Court invalidated global tariffs introduced by U.S. President Donald Trump. In response to the ruling, Trump announced temporary across-the-board tariffs of 10%, later increasing them to 15%.

Brussels Insists on Agreed Tariff Ceiling

In a strongly worded statement, the Commission emphasized that the current situation undermines the “fair, balanced, and mutually beneficial” trade framework outlined in last year’s joint EU-U.S. agreement.

Under that deal, the United States committed to a 15% tariff ceiling on most EU goods, with certain sector-specific tariffs — such as those on steel — remaining in place. Some products, including aircraft and spare parts, were granted zero-tariff treatment. In exchange, the EU removed duties on numerous U.S. exports and withdrew plans for retaliatory measures.

“In particular, EU products must continue to benefit from the most competitive treatment, with no increases in tariffs beyond the clear and all-inclusive ceiling previously agreed,” the Commission said, warning that unpredictable trade measures erode confidence across global markets.

Escalating Transatlantic Tensions

The Commission’s latest remarks marked a notable shift from its more cautious initial reaction, when it said it was studying the court’s decision and maintaining contact with U.S. authorities.

On Saturday, Trade Commissioner Sefcovic discussed the matter with U.S. Trade Representative Jamieson Greer and Commerce Secretary Howard Lutnick, according to the EU executive.

Brussels argues that any tariff increase beyond the agreed threshold would violate the spirit and letter of the bilateral accord. While no immediate countermeasures were announced, officials signaled that legal certainty and predictability are essential for sustaining transatlantic investment flows.

The dispute adds fresh strain to EU-U.S. economic relations, at a time when both sides have pledged closer cooperation on trade, supply chains and industrial policy.
