In brief

The Department of Homeland Security published a notice in the Federal Register on October 20, 2026. It announces that the Secretary of Homeland Security has issued an order covering information technology products and services from Hangzhou DeepSeek Artificial Intelligence Co., Ltd and its affiliates.

The order has two parts. It excludes these products from federal civilian agency procurement, and it requires their removal from civilian agency systems. The notice points to a signed order in an appendix and a regulations.gov docket, but the supplied text does not reproduce that order's reasoning or deadlines.

Main points

The order covers products and services from Hangzhou DeepSeek Artificial Intelligence Co., Ltd and affiliated entities as defined in 48 CFR 2.101.
It bars these products from federal civilian agency procurements.
It requires removal of DeepSeek, affiliate, and third-party products built using DeepSeek implementations from civilian agency IT.
Authority comes from the Federal Acquisition Supply Chain Security Act of 2018 and 41 CFR 201-1.

The problem

DHS ordered federal civilian agencies to stop buying and to remove DeepSeek and affiliate products, including third-party products built on DeepSeek implementations, treating them as a federal supply chain security concern.

The rundown

The notice cites the Federal Acquisition Supply Chain Security Act of 2018, 41 U.S.C. 1321-1328, and implementing regulations at 41 CFR 201-1. It says the Secretary acted after reviewing the Federal Acquisition Security Council Recommendation and affiliated evidence.

The removal requirement extends beyond DeepSeek's own products to third-party products and services developed using DeepSeek implementations. Affiliates are defined by reference to 48 CFR 2.101.
