In a move to bolster domestic manufacturing and reduce dependency on foreign imports, US President Donald Trump has announced a 15% tariff on products made with polysilicon, a crucial component in the production of semiconductors and solar panels. This tariff, set to be implemented on December 4, targets the enhancement of local production capabilities amid growing concerns about China’s dominance in the polysilicon market.
Polysilicon, characterized by its ultra-pure form, is essential for creating semiconductors that support artificial intelligence systems and data centers, as well as for the development of solar cells and panels. As the leading global producer of polysilicon, China has been pivotal in supplying this material worldwide, prompting the US to rethink its supply chain strategies for economic and national security reasons.
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. These measures are designed to sustain the commercial viability of US polysilicon production while fortifying critical supply chains. In addition, the policy allows for the establishment of incentives aimed at encouraging companies to invest in domestic polysilicon and related manufacturing facilities.
China has expressed disapproval of the US’s decision, accusing it of leveraging national security concerns to unfairly limit Chinese businesses. This move, according to Chinese officials, could escalate protectionist trade practices and potentially disrupt the economic relationship between the two nations. Despite this tension, China continues to experience robust growth in its export sectors, particularly within electronics and artificial intelligence-related products.
Within the US, major polysilicon production is concentrated in two facilities: Hemlock Semiconductor in Michigan and Wacker Chemie in Tennessee. These sites are expected to benefit from the new tariff structure, which aligns with the broader governmental push to strengthen domestic production in high-value manufacturing sectors.
