In a strategic move to bolster domestic production and reduce dependence on China, US President Donald Trump has declared a 15% tariff on imported goods made with polysilicon, a crucial component in both semiconductor manufacturing and solar panels. Set to commence on December 4, this tariff is part of a broader initiative to strengthen the United States’ industrial base and enhance national and economic security.
Polysilicon, known for its ultra-pure silicon properties, plays a vital role in the production of semiconductors, which are essential for powering artificial intelligence systems and data centers, as well as in the creation of solar cells and panels. China currently dominates the global market as the leading producer of this material. The imposed tariffs will also introduce minimum import prices, setting them at $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 US administration has articulated that these measures aim to ensure the commercial viability of domestic polysilicon production facilities and reinforce critical supply chains that are linked to the nation’s economic and national security interests. However, the decision has drawn criticism from China, which accuses the US of exploiting national security concerns to unfairly target Chinese businesses, warning that such protectionist policies might disrupt bilateral trade relations.
Within the US, two key polysilicon production sites exist, operated by Hemlock Semiconductor in Michigan and Wacker Chemie in Tennessee. The new policy framework also opens the door for the US government to establish incentives for firms investing in the domestic production of polysilicon and related manufacturing capabilities. These measures come at a time when China continues to experience robust growth in its export sector, particularly in electronics, AI-related products, and other high-value manufacturing industries.
