The Department of Homeland Security has ordered U.S. Federal civilian agencies to remove products developed by Chinese artificial-intelligence company Hangzhou DeepSeek Artificial Intelligence Co. From their information-technology systems and barred them from buying the company’s products and services. The order also covers DeepSeek affiliates and third-party products or services developed using DeepSeek implementations.
DHS issued the order under the Federal Acquisition Supply Chain Security Act of 2018 after reviewing a recommendation from the Federal Acquisition Security Council and related evidence.
It does not create a general prohibition on private companies or individuals in the United States using DeepSeek products, and the order is separate from rules governing military and intelligence systems. Federal acquisition rules allow DHS to issue supply-chain security orders for civilian agencies, while the Defense Department and the intelligence community have separate authorities for their systems.
The decision follows earlier U.S. And allied restrictions on DeepSeek in government environments. In February 2025, South Korea blocked access to the service on computers at its foreign, trade and defense ministries amid concerns about user-data collection and possible information leaks. Civilian agencies, the immediate requirements are to remove covered technology already present in their systems and exclude it from future procurements, subject to the procedures and waiver mechanisms established for federal supply-chain security orders.
