Description
This temporary final rule issued by the Bureau of Industry and Security under the Department of Commerce establishes measures to restrict the stockpiling of polysilicon and its derivatives by importers ahead of import adjustments effective December 4, 2026. The rule outlines criteria and processes for monitoring existing importers, limiting new importers' ability to stockpile, and imposing import prohibitions if necessary. It also provides procedures for companies to apply for waivers from import prohibitions and imposes import limitations on new importers registering on or after August 6, 2026. The rule is effective from September 22, 2026, through December 3, 2026, and aims to protect national security by preventing stockpiling that could undermine trade adjustments.
