The Europe trade deal will see the U.S. impose a 15% import tariff on most EU goods − half the threatened rate but much more than Europeans hoped for.

Tariffs are taxes charged on goods bought from other countries. Typically, they are a percentage of a product's value. So, a 15% tariff means that a $100 product imported to the US from the EU will have a $15 dollar tax added on top - taking the total cost to the importer to $115.

After months of negotiations, and the two sides exchanging threats of further tariffs and potential countermeasures, the European Union and the United States have finalized terms of a deal that offers the bloc a reduced tariff rate in return for billions of dollars' worth of purchases and investments.
