Decoupling from Foreign Adversarial Battery Dependence Act

This bill stops the Department of Homeland Security (DHS) from using its money to buy batteries from certain companies tied to China, starting October 1, 2027. This includes well-known makers like CATL and BYD, plus companies on U.S. government restricted lists and any of their subsidiaries. The rule also covers devices that use these batteries if those companies make the device or most of the battery parts .

DHS can make exceptions in narrow cases: if the batteries pose no national security, data, or infrastructure risk and there’s no similar or better, affordable option from an allowed supplier, or if the batteries are only for research, testing, training, or analysis. If DHS grants a waiver, it must tell Congress within 15 days. DHS also has to report on how this will affect its missions and costs across its agencies, including Border Patrol, ICE, Secret Service, TSA, Coast Guard, FEMA, and CISA.

• Who is affected: DHS and its agencies; companies selling batteries or equipment that uses these batteries to DHS.
• What changes: DHS cannot buy batteries from listed companies and those on certain U.S. restricted lists, unless a waiver applies.
• When: The buying ban begins October 1, 2027; reporting and waiver notice rules begin after the bill becomes law .
