On December 4, US President Donald Trump will implement a 15% tariff on imported goods that are manufactured using polysilicon, a critical component in semiconductor and solar panel production. The primary goal of this tariff is to bolster domestic manufacturing capabilities and lessen dependence on China, which is currently the dominant global producer of this ultra-pure silicon material. Polysilicon is essential for the creation of semiconductors utilized in artificial intelligence systems and data centers, as well as in the production of solar cells and panels.
Besides the tariff, the new policy introduces minimum import prices, setting costs 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. This strategic move by the US administration is intended to support the viability of domestic polysilicon production facilities and enhance the resilience of supply chains that are crucial to both economic and national security interests.
China has expressed criticism regarding the United States’ decision, accusing it of exploiting national security concerns to impose restrictions on Chinese businesses. The Chinese government warns that such protectionist measures may lead to disruptions in trade relations between the two nations. Meanwhile, China continues to experience significant export growth, especially in sectors such as electronics and artificial intelligence-related products, which are considered high-value manufacturing industries.
In the United States, two significant polysilicon production facilities are currently operational, managed by Hemlock Semiconductor located in Michigan and Wacker Chemie in Tennessee. As part of the new policy framework, the US government is also permitted to create incentives for companies that invest in polysilicon and related manufacturing facilities domestically. This initiative is part of a broader effort to encourage the growth of domestic production capabilities in critical technological sectors.
