In a bid to boost domestic production and curb dependency on China, US President Donald Trump has mandated a 15% tariff on imports of products made with polysilicon, an essential component in the manufacturing of semiconductors and solar panels. This tariff, set to be implemented on December 4, is part of a broader strategy to enhance the economic and national security by reinforcing critical supply chains within the United States.
Polysilicon, a highly purified form of silicon, is pivotal in the production of semiconductors that facilitate advanced technologies such as artificial intelligence systems and data centers, alongside its use in solar cells and panels. Currently, China dominates the global market as the leading producer of this material. In addition to the tariff, the new policies dictate minimum import prices, including $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 justified these measures as necessary to ensure the commercial viability of domestic polysilicon production facilities. By doing so, they aim to secure the supply chains that are critical to both economic interests and national security. Meanwhile, China has criticized the US’s move, accusing it of exploiting national security as a pretext to impose trade restrictions on Chinese businesses, and cautioned that such protectionism could strain the trade relations between the two nations.
Within the United States, two major facilities handle polysilicon production: Hemlock Semiconductor in Michigan and Wacker Chemie in Tennessee. The newly announced tariff policy also opens the door for the US government to create incentives for companies that invest in domestic polysilicon and related manufacturing facilities, potentially encouraging further growth and innovation in the sector.
This development comes amidst China’s continued robust growth in exports, particularly in sectors such as electronics and artificial intelligence-related products, as well as other high-value manufacturing industries. The US’s move to impose tariffs is a clear indication of its intent to compete more aggressively in these critical areas by bolstering its own production capabilities.
