特朗普签署公告，对多晶硅衍生品征收15%关税

The Odaily Planet Daily reported that U.S. President Donald Trump signed a proclamation on August 6, local time, imposing a 15% tariff on imports of polysilicon derivative products, the core raw material for semiconductors, in response to the threat these imports pose to U.S. national security.

The proclamation sets a minimum import price of $21 per kilogram for polysilicon, and $100 per kilogram for polysilicon ingots and wafers. The measures will take effect at 12:01 a.m. EST on December 4.

The U.S. Department of Commerce launched a Section 232 investigation under the Trade Expansion Act targeting polysilicon in July last year. Trump stated that polysilicon is a foundational material supporting the security of the U.S. semiconductor and solar power supply chains, and that this measure is intended to rebuild the U.S. polysilicon industry.
