The United States will respect tariff caps in trade deals struck with the European Union, Japan and other countries, and planned U.S. tariffs over forced labor provide the legal basis to do so, U.S. Trade Representative Jamieson Greer said on Thursday.

“We understand that a deal is a deal,” Greer told reporters on the sidelines of an OECD ministerial meeting in Paris.

Washington has struck deals with Brussels and Tokyo that limit U.S. tariffs on most EU or Japanese imports to a maximum of 15%.

However, Greer’s office on Tuesday unveiled a new set of tariffs on 60 countries after determining that they had failed to curb trade in goods made with forced labor. The EU would face a 10% tariff and Japan 12.5%. A further Section 301 investigation into excess manufacturing capacity could see overall tariffs on the two economies’ goods push well past 15%.

Greer, talking about the EU trade deal, said the agreement acknowledged that the U.S. could impose tariffs “up to a certain level” and that the Section 301 investigations gave U.S. President Donald Trump the authority to do so.

EU Trade Commissioner Maros Sefcovic, who spoke with Greer at the OECD meeting, said both sides agreed that “the deal is the deal”, which meant for the European side the terms agreed at Turnberry with an all-inclusive 15% tariff.

Sefcovic said EU countries had been surprised to find themselves targeted by tariffs over forced labor on account of their high labor standards, but he expected the European Parliament to approve the Turnberry deal with the Trump administration.

The EU is working to introduce a ban in December 2027 across the bloc on all products involving forced labor, irrespective of whether they originate in the EU or in a third country, he said.
