The European Commission has demanded the United States adhere to the terms of a 2025 EU-U.S. trade agreement, rejecting any increase in tariffs following a Supreme Court decision invalidating President Trump's global levies. A 15% U.S. tariff rate for most EU goods, established last year, remains the agreed ceiling, the Commission stated. Trump's subsequent hike of tariffs to 15% across the board threatens to override these terms, potentially eliminating zero-tariff exemptions for products like aircraft and spare parts.

The EU executive emphasized that a deal is a deal, warning unpredictable tariffs undermine global market confidence. This dispute highlights the fragility of the agreement and the risk of escalating trade tensions between the world's largest trading partners.
