United Solar said it supports new U.S. trade measures that set a minimum import price of US$21 per kilogram for polysilicon and add a 15 percent ad valorem duty (value-based import tariff) on downstream derivatives including ingots, wafers, solar cells, and modules. The measures, signed in a Proclamation on August 6, 2026 and effective December 4, 2026, apply the polysilicon floor to imports from all origins, which the company said may move U.S. buyers beyond unit price alone toward resilience, traceability, and security of supply. United Solar said the structure keeps raw polysilicon accessible while encouraging more domestic conversion in the United States, and noted that the Proclamation also allows the Secretary of Commerce to grant tariff relief to companies that commit to onshoring the solar value chain. The company highlighted its 100,000-ton-per-year Sohar Free Zone facility in Oman, which began operations in January 2026, as a source of FEOC-compliant (meeting Foreign Entity of Concern rules), fully traceable high-purity polysilicon for tier-one manufacturers.
