The U.S. Department of Commerce has announced preliminary anti-dumping duties of 93.5% on imports of anode-grade graphite from China, a key material used in the production of lithium-ion batteries for electric vehicles (EVs). This decision follows a ruling that Chinese graphite imports were unfairly subsidized and sold at less than fair market value. The tariff targets approximately $347 million worth of Chinese graphite imports and raises total tariffs on these materials to 160%. The move is part of the Trump administration's efforts to boost domestic battery material production but is expected to increase costs for battery manufacturers and potentially delay renewable energy expansion. China controls between 70% and 90% of global battery material processing, particularly graphite, which accounts for 92% of the market in this segment. The announcement has led to a rally in shares of non-Chinese graphite producers, including Canadian firms Nouveau Monde and Northern Graphite. The U.S. action also comes amid ongoing trade tensions with China and follows Beijing's restrictions on battery technology transfers. A Chinese Foreign Ministry spokesperson criticized the U.S. measures as self-defeating and likely to harm American companies and consumers.
