New 15% tariff and minimum import price program imposed on polysilicon and derivatives, effective 120 days after Aug. 6, 2026.
The President has signed a Proclamation imposing a minimum import price program on polysilicon and its derivatives and a 15% ad valorem tariff on downstream derivative products. These measures, effective 120 days after August 6, 2026, directly impact import costs and sourcing for polysilicon-related supply chains. Importers must assess affected products, model cost impacts, and prepare to adjust classifications, pricing, and sourcing before the effective date.
