The Trump administration said Friday it would increase tariffs on aircraft coming from the European Union, as its dispute with the bloc over subsidies for plane manufacturers remains unresolved.

Beginning March 18, airplanes from France, Germany, Spain and the U.K. will be subject to 15% tariffs, up from a 10% tariff that took effect in October.

The U.S. initially was authorized to impose the tariffs by a ruling at the World Trade Organization following a 15-year legal battle with the EU over support programs for aircraft manufacturers Airbus SE and its U.S. rival, Boeing Co.

As part of the dispute, the U.S. trade representative also imposed tariffs in October on a range of EU food products, including certain wines, cheeses and olives. Those tariffs were set in October at 25% and weren’t raised on Friday. The USTR has said about $7.5 billion worth of goods are affected by the tariffs, a figure which was unchanged by the latest action.

The USTR also had said that it might change the items affected by tariffs, but it made just a small tweak Friday to its original list, removing prune juice but adding certain kitchen knives from France and Germany to the list of goods subject to a 25% tariff.
