The US Commerce Department is set to impose a steep, preliminary 93.5% anti-dumping tariff on graphite imports from China, a move that directly targets a critical electric vehicle (EV) battery material. Chinese sources currently supply around two-thirds of the US graphite market, and the new duties are expected to bring the total tariff burden to approximately 160%.
The action follows claims that Chinese producers are dumping graphite at unfairly low prices, distorting the market through state subsidies. A final determination is expected by 5 December 2025.
The announcement sent shares of non-Chinese graphite producers sharply higher. Companies based in Australia and Canada, as well as US-listed firms with domestic production plans, saw immediate investor interest. Some, including those supported by US government programmes, rallied as much as 15 to 25%, helped by recent federal funding commitments to build large-scale synthetic graphite facilities.
The tariff decision is a clear signal of the US government’s intent to secure critical mineral supply chains and reduce dependence on China, particularly in the battery space. Graphite has been singled out by the International Energy Agency as one of the most vulnerable materials due to its highly concentrated processing in China. However, concerns remain about the US’s ability to meet graphite demand domestically in the short term, with battery manufacturers warning that the current local capacity may fall short of quality and volume requirements.
The financial impact could be significant. Analysts suggest the new tariff might add around US$7 per kilowatt-hour to battery costs, potentially offsetting part of the EV tax credit benefits under the Inflation Reduction Act and squeezing margins for manufacturers sourcing graphite from Asia.
While the tariff creates challenges for downstream battery and EV makers, it opens up opportunity for graphite producers outside of China. Projects in North America and allied jurisdictions may attract new investment, and the policy shift could accelerate the development of domestic and alternative supply chains.
