TURNBERRY, Scotland, July 27 (Reuters) - The U.S. struck a framework trade agreement with the European Union on Sunday, imposing a 15% import tariff on most EU goods - half the threatened rate - and averting a bigger trade war between the two allies that account for almost a third of global trade.

U.S. President Donald Trump and European Commission President Ursula von der Leyen have announced a sweeping trade deal.

European steelmakers are among the biggest losers from the U.S. and European Union's tariff deal, adding to the problems of an industry already under pressure from multiple directions. Steel and aluminum tariffs are set to stay at 50%.

Sir Keir Starmer will on Monday seek to emphasise Britain’s newfound competitive advantage over the EU on transatlantic trade when he urges US President Donald Trump to quickly enact zero tariffs on UK steel.

The deal was struck less than a week before the U.S. threatened to levy a much higher 30% tariff on European goods.

Pennsylvania's Republican U.S. senator and the HUD secretary toured the Braddock facility to see how the U.S. Steel-Nippon Steel deal affects workers and the surrounding community.

A lawsuit filed by Nippon Steel Corp. and United States Steel Corp. against rival Cleveland-Cliffs Inc., Cliffs CEO Lourenco Goncalves and United Steelworkers International President David McCall is moving forward.

Steel producers like Cleveland Cliffs and Steel Dynamics both said this week that they raised prices after President Trump imposed a 50 percent tariff on imports.

The U.S. and European Union agreed to a deal that will see the bloc face 15% tariffs on most of its exports, including automobiles, staving off a trade war that could have delivered a hammer blow

U.S. Steel made changes to its senior leadership team after it was acquired by Nippon Steel for $14.9 billion.

A global plunge in prices, led by increased production from China, and U.S. tariffs threaten steel manufacturing, which has long been a symbol of national might.
