President Donald Trump has announced a 15% tariff on imported products made with polysilicon, a critical material in semiconductor and solar panel manufacturing. This tariff, effective from December 4, aims to boost domestic production and lessen the United States’ dependence on China. Polysilicon, an ultra-pure form of silicon, is essential for creating semiconductors that drive artificial intelligence systems and data centers, as well as solar cells and panels. Currently, China leads the global production of this material.
The tariff policy introduces minimum import prices for various polysilicon forms and related 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. The U.S. administration believes these measures will enhance the commercial viability of domestic polysilicon production and fortify supply chains crucial to economic and national security.
While the U.S. seeks to bolster its polysilicon industry, China has reacted critically to the tariff, accusing the U.S. of using national security issues as a pretext to limit Chinese businesses. China warns that such protectionist policies could disrupt trade relations between the two nations. Despite the tension, the U.S. continues to focus on strengthening its domestic capabilities, with two major polysilicon production facilities currently operating in Michigan and Tennessee, managed by Hemlock Semiconductor and Wacker Chemie, respectively.
In addition to the tariffs, the new policy permits the U.S. government to offer incentives to companies that invest in domestic polysilicon and related manufacturing operations. This move comes as China’s export sector experiences robust growth, particularly in electronics, artificial intelligence-related products, and other high-value manufacturing areas, further intensifying the competition between the two economic powers.
