Trump is breaking the Turnberry deal over cars. Semiconductors are next in line.

Trump's 25% EU Auto Tariff Breaches Turnberry Agreement

May 1, 2026 - 4:51 pm

TL;DR

Trump announced he will raise tariffs on EU cars and trucks to 25% next week, accusing the bloc of non-compliance with the Turnberry Agreement without specifying the violation. The agreement, signed in July 2025, also covers semiconductors, AI chips, and digital trade. Trump's willingness to breach the auto provisions establishes a precedent that threatens the entire transatlantic tech trade framework.

The Deal

The Turnberry Agreement, formally known as the Agreement on Reciprocal, Fair, and Balanced Trade, was signed between the United States and the European Union in July 2025. Key points include:

  • A 15% tariff ceiling on nearly all EU goods entering America, including cars, car parts, semiconductors, and pharmaceuticals.
  • The EU agreed to eliminate tariffs on all US industrial goods, purchase $750 billion in American energy exports, and deliver $600 billion in investments into the United States by 2028.
  • Asymmetric terms favoring the U.S. were accepted by the EU due to the alternative of a worse scenario.

Recent Developments

Trump announced on Truth Social that he will raise tariffs on EU cars and trucks to 25% next week, citing non-compliance with the Turnberry Agreement, though he did not specify the alleged violation. This move follows warnings from the European tech industry months ago that any tariffs would impact both hardware and software. The question now is whether this escalation will be limited to cars or expand further.

Legal Uncertainty

A significant legal shift occurred on February 20, 2026, when the U.S. Supreme Court ruled in Learning Resources Inc. v. Trump that the International Emergency Economic Powers Act does not authorize the president to impose sweeping tariffs. This ruling changed the legal framework for administering tariffs, creating ambiguity regarding the enforceability of the Turnberry Agreement's provisions and their timelines. The EU froze its ratification process due to this uncertainty.
