S. 450 — Decoupling from Foreign Adversarial Battery Dependence Act

This section prohibits the Department of Homeland Security (DHS) from obligating funds to procure batteries produced by specified entities beginning October 1, 2027. Specified entities include certain Chinese companies (Contemporary Amperex Technology Company Limited (CATL), BYD Company Limited, Envision Energy Limited, EVE Energy Company Limited, Gotion High-tech Company Limited, and Hithium Energy Storage Technology Company Limited), entities on lists under the Uyghur Forced Labor Prevention Act, Chinese military companies identified under section 1260H of the William M. (Mac) Thornberry National Defense Authorization Act for Fiscal Year 2021, entities on the Commerce Entity List (Supplement No. 4 to part 744 of title 15, C.F.R.), and any subsidiaries or successors; a battery is treated as produced by such an entity if it assembles or manufactures the final product using the battery or provides a majority of the battery's components. This section authorizes the DHS Secretary to waive the prohibition if batteries pose no national security, data, or infrastructure risk and no suitable alternatives exist, or if solely for research, evaluation, training, testing, or analysis, with notification to specified congressional committees within 15 days. This section requires the DHS Secretary to submit to those committees, within 180 days of enactment, a report on anticipated mission and cost impacts on DHS components including U.S. Customs and Border Protection, U.S. Immigration and Customs Enforcement, United States Secret Service, Transportation Security Administration, United States Coast Guard, Federal Protective Service, Federal Emergency Management Agency, Federal Law Enforcement Training Centers, and Cybersecurity and Infrastructure Security Agency.
