President Donald Trump signed a proclamation Thursday imposing a 15% tariff and a set of minimum import prices on polysilicon and its derivative products, including solar wafers, cells, and modules, citing national security concerns about U.S. dependence on foreign supply chains.
The measures take effect December 4, according to the White House. The minimum import prices are set at $21 per kilogram for raw polysilicon, $100 per kilogram for ingots and wafers, $0.22 per watt for solar cells, and $0.38 per watt for solar modules. Importers who fail to certify that their first domestic sale of covered products meets those price floors will face a specific tariff equal to the applicable minimum price.
