Over $600 billion in European goods were imported by the U.S. last year. New tariffs from President Trump will likely hit these popular categories the hardest.

The trade threats could reduce exports to the United States and dampen investment in Europe, dealing a blow to growth at a time when the continent is already facing a lackluster economy.

Trump spoke to reporters from the Oval Office about his decision, saying it was an “amazing day.” When asked if prices would rise as a result of the tariffs, he said that they “could go up somewhat” at first, but then “prices will also go down.”
