Trump administration to impose 15% tariff and price floor on polysilicon

polysilicon tariff price floor Trump administration China solar semiconductor

The Trump administration is set to announce a 15% tariff on imports of polysilicon and related products, together with minimum import price floors for polysilicon, silicon wafers, solar cells and modules. The measures, based on a Section 232 national‑security investigation by the U.S. Department of Commerce, aim to protect domestic polysilicon factories owned by Hemlock Semiconductor and Wacker Chemie and to curb China’s dominance in the solar‑panel and semiconductor supply chains. The policy is expected to be disclosed in early August 2026 and follows a year‑long probe into the material’s strategic importance.

Market reaction was immediate: shares of Corning, First Solar, T1 Energy and other U.S. solar‑related companies rose after the Reuters report. Chinese officials have criticized the move, urging the United States to halt the tariffs and price‑floor measures. Analysts say the combined tariff and price‑floor system could reshape the economics of U.S. solar‑panel and semiconductor manufacturing and heighten trade tensions with China.
