The U.S. Department of Commerce initiated new Section 232 investigations to assess the national security implications of imports of polysilicon and unmanned aircraft systems (UAS) on July 1, 2025.

Specifically, the Commerce Department is investigating polysilicon and its derivatives, and UAS and its parts and components. Polysilicon is a critical component in integrated circuits and solar panels. For polysilicon, the Commerce Department is seeking public comments on factors such as the:

  • Current and projected demand for polysilicon and its derivatives in the United States.
  • Extent to which domestic production of polysilicon and its derivatives can meet domestic demands.
  • Potential for export restrictions by foreign nations, including the ability of foreign nations to weaponize their control over supplies of polysilicon and its derivatives.
