President Donald Trump announced Friday that he will increase the tariffs on cars and trucks imported from the European Union to 25 percent, saying the policy will go into effect next week.

In a post on Truth Social, the president wrote that the tariffs are being imposed because he said the EU is failing to comply “with our fully agreed to Trade Deal” and that those import taxes will not be applied on cars and vehicles made in the United States.

“Many Automobile and Truck Plants are currently under construction, with over 100 Billion Dollars being invested, A RECORD in the History of Car and Truck Manufacturing,” Trump added. “These Plants, staffed with American Workers, will be opening soon — There has never been anything like what is happening in America today.”

Trump did not specify a day for when the tariffs will be imposed, only saying the duties would be levied next week.

The president also did not say under which authority he would implement the tariffs. The Supreme Court in February largely scrapped earlier tariffs that were brought by the Trump administration under the 1977 International Emergency Economic Powers Act.

Before the high court ruling was issued, Trump and Treasury Secretary Scott Bessent said the administration has other authorities with which to issue tariffs.

In July, Trump and European Commission President Ursula von der Leyen had agreed to a trade deal between the EU and United States that set a 15 percent tariff on most goods. Both the U.S. government and the EU had previously confirmed their commitment to preserving the trade framework, known as the Turnberry Agreement, which was named after Trump’s golf course in Scotland.

The initial agreement had been a tariff ceiling of 15 percent on goods from the EU, but the Supreme Court ruling reduced that to 10 percent as the Trump administration launched a new set of import taxes based on other laws. The Trump administration is in the middle of investigations on trade imbalances and national security risks to impose a new tariff regime.

“A deal is a deal,” the European Commission said following the Supreme Court tariff ruling in February. “As the United States’ largest trading partner, the EU expects the U.S. to honor its commitments set out in the Joint Statement—just as the EU stands by its commitments. 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.”

A year ago, Trump had imposed 30 percent tariffs on the EU as part of his “Liberation Day” announcement that also placed a 10 percent baseline tariff on nearly every country in the world. The 15 percent reduction announced in July following negotiations between the EU and United States had served as a reprieve.

Trump has used tariffs, or the threat of them, in all manner of negotiations, including non-economic matters, maintaining that they are a key tool in ending armed conflicts and upholding peace.

The tariff announcement Friday also comes in the midst of the U.S.–Iran war and Trump’s push to EU NATO member states to help in the conflict, namely to secure the Strait of Hormuz waterway. Some European members of the bloc have also not allowed the U.S. military to use their airspace during the conflict.

Trump has warned on multiple occasions that his administration would re-examine the U.S. relationship with the military alliance.

“They weren’t there for us,” he told reporters in mid-April. “We pay trillions of dollars to NATO, and they weren’t there for us.”
