business π US hits polysilicon imports with new tariffs
President Donald Trump signed an order on Thursday to impose tariffs on polysilicon imports, a crucial material for solar panels and semiconductors. This action follows a year-long Commerce Department probe into these imports. The investigation began in July 2025 under Section 232 of the Trade Expansion Act of 1962. Officials aim to secure the supply chain domestically and prevent product dumping from China. Further details regarding the tariff levels have not been immediately disclosed by the department.
