ICYMI: BIS Initiates 232 Investigations of UAS and Polysilicon Imports

On July 15, 2025, the Bureau of Industry and Security announced Section 232 National Security Investigations of: (i) Unmanned Aircraft Systems (UAS) and their parts/components, and (ii) polysilicon and related derivatives.

The Federal register notices are available here (UAS) and here (polysilicon).

BIS is specifically interested in the following information:

1. The current and projected demand for these products and the extent to which domestic production can meet this demand
2. The role of foreign supply chains, particularly of major exporters, in meeting United States demand 
3. The concentration of U.S. imports from a small number of suppliers and the associated risks
4. The impact of foreign government subsidies and predatory trade practices 
5. The economic impact of artificially suppressed prices due to foreign unfair trade practices and state-sponsored overproduction
6. The potential for export restrictions by foreign nations
7. The feasibility of increasing domestic capacity to reduce import reliance
8. The impact of current trade policies on domestic production and whether additional measures, including tariffs or quotas, are necessary to protect national security

The deadline to submit comments is August 6, 2025.

The investigations could result in new trade restrictions, including tariffs. If you import products covered under these investigations, make your voice heard by filing a comment.
