On August 6 local time, the U.S. government announced that, under Section 232 of the Trade Expansion Act of 1962, it would implement a minimum import price mechanism and impose a 15% tariff on imported polysilicon and its derivative products starting from December 4, 2026. Specifically, the minimum import price for polysilicon is set at $21 per kilogram, while for polysilicon ingots and wafers, it is $100 per kilogram. This move aims to strengthen the U.S. domestic semiconductor and solar supply chains and enhance its competitiveness in the fields of artificial intelligence and energy.
