Decoupling from Foreign Adversarial Battery Dependence Act

HR 1166 prohibits the Department of Homeland Security (DHS) from using funds to buy batteries produced by specific Chinese companies, including CATL, BYD, and others listed in the bill, starting October 1, 2027. It directly affects DHS procurement for all its agencies, such as U.S. Customs and Border Protection, Immigration and Customs Enforcement, and the Transportation Security Administration. The bill defines "produced by" to include entities assembling final products or supplying most components of the batteries. DHS may waive the ban for national security reasons or research, but must report on cost and mission impacts within 180 days of enactment.
