The European Union will implement retaliatory measures against the steel and aluminum tariffs imposed by U.S. President Donald Trump by imposing additional duties on $23 billion worth of U.S. imports starting next Tuesday. These counter-tariffs involve a 25% duty on steel, aluminum, and cars, as well as a 20% tariff on other goods, aligning with Trump's strategy to target nations with high trade barriers. The EU's response to the U.S. metal tariffs, approved by EU members, focuses on the initial phase covering $3.9 billion of U.S. products, including corn, motorcycles, dishwashers, and orange juice. The plan unfolds in three phases and aims to influence U.S. businesses to urge the U.S. government to de-escalate the trade dispute. Companies like Whirlpool, Stanley Black & Decker, and Harley-Davidson may be impacted by the EU's countermeasures.
