The United States and the European Union on Thursday locked in a framework trade deal reached last month that includes a 15% U.S. tariff on most EU imports, including autos, pharmaceuticals, semiconductors and lumber.

The EU-US trade agreement is poised to cut the US import tax on cars from the EU from 27.5% to 15%. However, details released Thursday reveal that the lower rate won’t take effect until the EU takes separate action to reduce its own tariffs on US goods.
