The Department of Homeland Security has issued an order excluding information technology products and services developed by Hangzhou DeepSeek Artificial Intelligence Co., Ltd from federal civilian agency procurements and requiring the removal of DeepSeek products from civilian agency information technology, according to a notice published in the Federal Register on October 20, 2026.
The order covers DeepSeek's affiliated entities as defined in 48 CFR 2.101, and extends to third-party products and services developed using DeepSeek implementations.
The Secretary of Homeland Security issued the order under the Federal Acquisition Supply Chain Security Act of 2018 (41 U.S.C. 1321-1328) and implementing regulations at 41 CFR 201-1, following review of a Federal Acquisition Security Council recommendation and affiliated evidence.
FASCSA orders are part of a federal supply-chain risk framework that lets designated officials bar specific products or services from federal systems. This order applies to federal civilian executive branch agencies.
The signed order is filed in DHS Docket No. DHS-2026-0628 at regulations.gov. The notice was signed by DHS General Counsel James H. Percival II and filed October 19, 2026.
DeepSeek, the Hangzhou-based AI lab whose low-cost reasoning models drew global attention, has faced growing restrictions in government environments. The FASCSA order formalizes an exclusion and removal mandate across federal civilian IT rather than agency-by-agency guidance.
