President Donald Trump imposed a 15% tariff and minimum import price requirements on imported polysilicon on Thursday, targeting the raw material used in semiconductors and solar panels. China controls more than 90% of global polysilicon production.
The measures, introduced under Section 232 of the Trade Expansion Act, will take effect on Dec. 4.
Officials Frame Move as National Security Priority
The proclamation states the plan will help ensure the commercial viability of U.S. polysilicon production needed to meet economic and national security requirements.
Chips account for just 2.4% of global polysilicon demand, meaning solar’s larger appetite for the material effectively underwrites U.S. production capacity needed for chipmaking, according to the Semiconductor Industry Association.
The proclamation also allows the Commerce Department to establish an incentive program for companies that invest in factories producing polysilicon or related products.
Embassy of the People’s Republic of China in the USA did not immediately respond to Benzinga‘s request for comment.
Hemlock Semiconductor, a joint venture between Corning Inc. (NYSE:GLW) and Japan’s Shin-Etsu Handotai, operates the Michigan plant. Germany’s Wacker Chemie runs the Tennessee facility. Together, they operate the only two polysilicon plants in the United States.
In a statement to Benzinga, Wacker Chemie said it is “currently reviewing the 232 remedy to thoroughly understand its impact” on U.S. operations, which employ roughly 1,500 people.
The company added that it appreciates the administration’s continued engagement given the implications for semiconductor supply chain resilience, advanced computing infrastructure and broader U.S. defense and security interests.
Tim Brightbill, a trade attorney with Wiley Rein who has brought several trade cases against Chinese solar companies, warned that the delayed enforcement could trigger a surge of imports in the coming months, Reuters reported.
Mark Widmar, CEO of Phoenix-based solar technology company First Solar, Inc. (NASDAQ:FSLR), called the measure “one of the most strategically significant trade measures in decades.” He said the action includes a minimum import price, an ad valorem tariff, and enforcement measures aimed at closing loopholes used by China-linked supply chains.
How Market Reacted
In Friday pre-market trading, First Solar led gains, up 8.95% to $266. NextEra Energy (NYSE:NEE) rose 0.12%, Sunrun (NASDAQ:RUN) gained 1.39%, and SolarEdge Technologies (NASDAQ:SEDG) added 1.93%.
The announcement contrasts with Trump’s broader rollback of clean energy. A July report from the Minneapolis-based non-profit BlueGreen Alliance found that his policies led to the cancellation or delay of $82.8 billion in clean energy, manufacturing and electric vehicle projects across the country.
