FRANKFURT, Germany (AP) — President Donald Trump and European Commission President Ursula von der Leyen have announced a sweeping trade deal that imposes 15% tariffs on most European goods, warding off Trump's threat of a 30% rate if no deal had been reached by Aug. 1.

The tariffs, or import taxes, paid when Americans buy European products could raise prices for U.S. consumers and dent profits for European companies and their partners who bring goods into the country.

Here are some things to know about the trade deal between the United States and the European Union:

Many details remain to be decided

Trump and von der Leyen's announcement, made during Trump's visit to one of his golf courses in Scotland, leaves many details to be filled in.

The headline figure is a 15% tariff rate on “the vast majority” of European goods brought into the U.S., including cars, computer chips and pharmaceuticals. It's lower than the 20% Trump initially proposed, and lower than his threats of 50% and then 30%.

Von der Leyen said the two sides agreed on zero tariffs on both sides for a range of “strategic” goods: Aircraft and aircraft parts, certain chemicals, semiconductor equipment, certain agricultural products, and some natural resources and critical raw materials. Specifics were lacking.

She said the two sides “would keep working” to add more products to the list.

Additionally, the EU side would purchase what Trump said was $750 billion (638 billion euros) worth of natural gas, oil and nuclear fuel to replace Russian energy supplies, and Europeans would invest an additional $600 billion (511 billion euros) in the U.S.

50% U.S. tariff on steel stays and others might, too

Trump said the 50% U.S. tariff on imported steel would remain; von der Leyen said the two sides agreed to further negotiations to fight a global steel glut, reduce tariffs and establish import quotas — that is, set amounts that can be imported, often at a lower rate.

Trump said pharmaceuticals were not included in the deal. Von der Leyen said the pharmaceuticals issue was “on a separate sheet of paper” from Sunday's deal.

Where the $600 billion for additional investment would come from was not specified. And von der Leyen said that when it came to farm products, the EU side made clear that “there were tariffs that could not be lowered,” without specifying which products.

The 15% rate is higher than in the past

The 15% rate removes Trump's threat of a 30% tariff. It's still much higher than the average tariff before Trump came into office of around 1%, and higher than Trump's minimum 10% baseline tariff.
