BRUSSELS (AP) — The European Union is working on the presumption that the United States will impose a 15% tariff on most EU exports from Friday, even though the two sides have yet to complete a key document clarifying how the agreement will operate.

EU Ambassador Jovita Neliupšienė discusses China, Russia, U.S. ties and the 'existential' issue of security with Newsweek.

The biggest winners in this deal are Europe’s carmakers. The US has collapsed various sector-specific duties on goods like aircraft, cars and automotive parts into the 15% ceiling. This effectively reduces tariffs on EU-made cars (from 27.5%).

The EU ’s other big concession was cutting its own tariffs on American cars and other industrial goods to zero, as well as giving some farm and fishery products better access to the European market. The liberalisation affects about a quarter of America’s exports to the EU, including cars and footwear; the rest already enter tariff-free.
