US-China polysilicon tariff dispute

Entities: China · United States · Alentejo · polysilicon · Wacker Chemie

Overview

In early August 2026 the White House announced a pending trade measure that would set a minimum import price and impose tariffs on polysilicon and related products, citing Section 232 national‑security concerns. The policy aims to protect the few U.S. producers—primarily Hemlock Semiconductor in Michigan and Wacker Chemie’s Tennessee plant—and to support domestic solar‑panel and semiconductor manufacturing, while warning that higher input costs could lengthen solar project pay‑back periods. The Trump administration moved quickly to formalise the response, planning a price‑floor mechanism that would trigger automatic tariffs if market prices fell below the set level. A Commerce Department report due in May 2026 and a presidential ruling expected in August 2026 would finalize the measure. On 4 August 2026 the administration confirmed a 15 % ad‑valorem tariff on imports of polysilicon, silicon wafers, solar cells and modules, coupled with minimum import price floors. The action, grounded in a Section 232 national‑security investigation, was intended to shield Hemlock Semiconductor and Wacker Chemie’s U.S. facilities and curb China’s dominance. Shares of U.S. solar‑related firms such as Corning, First Solar and T1 Energy rose after the announcement, while Chinese officials publicly condemned the tariffs and urged Washington to withdraw them. The combined tariff‑price‑floor regime is expected to reshape the economics of U.S. solar‑panel and semiconductor manufacturing and heighten trade tensions. At the same time, the United States continued to target the upstream segment of the solar supply chain. Roughly 84 % of U.S. solar‑panel imports in late 2023 originated from Southeast Asian assemblers that act as intermediaries for Chinese manufacturers. After the expiration of the earlier Section 201 safeguard tariffs in February 2026, a sharper tariff regime was introduced to curb imports of polysilicon and cells, reinforcing the broader effort to limit China’s dominance in the material.
