# Cotton Urges Commerce to Restrict CXMT

Senator Tom Cotton asked Commerce Secretary Howard Lutnick to add ChangXin Memory Technologies (CXMT) to the Commerce Department’s Entity List and consider using information and communications technology and services (ICTS) authorities to prohibit U.S. sales of CXMT products. Cotton’s letter cites the company’s existing military-company designation, export controls, and FY2023 NDAA limits on government procurement. No new restriction, solicitation, or contract is announced; broader restrictions, if adopted, could affect semiconductor sourcing and supplier compliance for government buyers and contractors.

- Companies sourcing memory chips for government work should assess whether CXMT products or related supply-chain exposure could be affected by existing restrictions cited in the letter.
- Any Entity List addition or ICTS prohibition would be a potential change to the procurement and sales environment, not a new contracting opportunity or current requirement announced by this signal.
- Contractors and suppliers may find it useful to distinguish the existing FY2023 NDAA procurement limits and export controls from the additional restrictions Cotton is asking Commerce to consider.

### Key Quotes
> I respectfully ask the Commerce Department to add CXMT to the Commerce Department’s Entity List to broadly deny the company access to U.S. technologies and technical support, including semiconductor manufacturing equipment and tools for any CXMT fabs. I also encourage you to exercise authorities through your information and communication technology services (ICTS) office to explore a prohibition on sales of CXMT products, especially as American and allied technologies are available.
