In a move aimed at bolstering domestic production and reducing dependence on China, U.S. President Donald Trump has announced a 15% tariff on imported products made with polysilicon. This tariff is set to take effect on December 4. Polysilicon, an ultra-pure form of silicon, is crucial for manufacturing semiconductors that power artificial intelligence systems and data centers, as well as solar cells and panels. The global leader in the production of this material is China.
The newly introduced measures also establish minimum import prices: $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 designed to enhance the economic viability of domestic polysilicon production and to fortify critical supply chains, which are considered vital for both economic and national security.
China has expressed criticism of this policy, accusing the United States of exploiting national security concerns to limit Chinese business operations. Beijing warns that such protectionist measures could potentially disrupt bilateral trade relations between the two economic powerhouses.
Currently, the United States hosts two major facilities dedicated to polysilicon production. Hemlock Semiconductor operates in Michigan, while Wacker Chemie runs another facility in Tennessee. The newly introduced policy also provides the U.S. government with the ability to create incentives aimed at encouraging companies to invest in domestic polysilicon production and related manufacturing facilities.
This tariff introduction occurs against the backdrop of China’s robust growth in exports, especially in the electronics sector, artificial intelligence-related products, and other high-value manufacturing areas. As the global landscape continues to evolve, these measures reflect a strategic effort by the U.S. to reinforce its domestic industries in the face of growing international competition.
