In a move aimed at bolstering domestic industry, US President Donald Trump has announced a 15% tariff on imports of products utilizing polysilicon, effective December 4. This material, crucial for producing semiconductors and solar panels, is predominantly sourced from China, the leading global producer. The tariff is part of a broader strategy to enhance domestic manufacturing capabilities and reduce dependency on Chinese imports.
Polysilicon, an exceptionally pure form of silicon, is essential for the manufacture of semiconductors, which are vital to the operation of artificial intelligence systems and data centers, as well as solar cells and panels. To support these industries, the US government has also introduced minimum import prices of $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 administration has emphasized that these measures aim to support the economic viability of domestic polysilicon production facilities and reinforce supply chains critical to both economic and national security. Currently, the United States hosts two significant polysilicon production sites, managed by Hemlock Semiconductor in Michigan and Wacker Chemie in Tennessee. The new policy framework also permits the establishment of incentives for firms investing in domestic polysilicon and related manufacturing operations.
China has responded critically to the US tariff, accusing the US of using national security as a pretext to curb Chinese business activities. Chinese authorities have warned that such protectionist measures could potentially disrupt trade relations between the two economic giants. Meanwhile, China continues to experience robust growth in its exports, notably in sectors like electronics and products associated with artificial intelligence and high-value manufacturing.
