In a significant move aimed at bolstering domestic manufacturing, US President Donald Trump has announced a 15% tariff on imported products made with polysilicon, which is a crucial component in both semiconductor manufacturing and solar panel production. Set to take effect on December 4, this tariff is designed to reduce reliance on Chinese imports, as China currently dominates the global production of polysilicon.
Polysilicon, an ultra-pure form of silicon, is essential for creating semiconductors that power artificial intelligence systems and data centers, as well as for producing solar cells and panels. In addition to the tariff, the US has introduced 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.
The US administration asserts that these measures are crucial for ensuring the commercial viability of domestic polysilicon production and reinforcing critical supply chains linked to economic and national security. Despite these intentions, the move has been met with criticism from China, which accuses the US of exploiting national security concerns to restrict Chinese businesses. China also warns that such protectionist measures could disrupt trade between the two nations.
Currently, the US hosts two significant polysilicon production facilities: Hemlock Semiconductor in Michigan and Wacker Chemie in Tennessee. The new policy allows for incentives to be established for companies that invest in the domestic production of polysilicon and related manufacturing facilities, further supporting the administration’s goal of enhancing national production capabilities.
This development comes at a time when China is experiencing strong growth in exports, particularly in sectors like electronics and artificial intelligence. The tariffs and associated measures are part of a broader strategy to ensure that the US maintains a competitive edge in these high-value manufacturing sectors.
