In a move aimed at bolstering domestic production and decreasing dependence on Chinese imports, U.S. President Donald Trump has announced a 15% tariff on imported products that incorporate polysilicon, a crucial material in both semiconductor manufacturing and solar panel production. This tariff is scheduled to go into effect on December 4. Polysilicon, known for its ultra-pure silicon form, is integral to creating semiconductors that drive artificial intelligence systems, data centers, and solar energy solutions, with China currently dominating global production of this material.
The newly introduced measures also specify minimum import prices for various forms of polysilicon products: $21 per kilogram for polysilicon, $100 per kilogram for polysilicon ingots and wafers, $0.22 per watt for solar cells, and $0.38 per watt for solar modules and panels. According to the U.S. administration, these steps are part of a strategic effort to ensure the commercial viability of the domestic polysilicon industry and to fortify supply chains that are vital to both economic interests and national security.
China has responded critically to the U.S. decision, arguing that national security concerns are being improperly used as a justification for restricting Chinese companies. Furthermore, Chinese officials warn that such protectionist measures could potentially disrupt trade relations between the two countries. This comes at a time when China is experiencing robust growth in its export sectors, particularly in electronics, artificial intelligence-related products, and other high-value manufacturing industries.
Currently, the U.S. polysilicon production landscape includes two major facilities operated by Hemlock Semiconductor in Michigan and Wacker Chemie in Tennessee. The new policy also permits the U.S. government to establish incentives for companies that choose to invest in domestic polysilicon and related manufacturing facilities. These incentives aim to enhance the competitiveness of U.S. production capabilities in the global market.
