This bill aims to restrict the Department of Homeland Security's (DHS) procurement of certain foreign-made batteries. Beginning on October 1, 2027 , DHS funds cannot be used to acquire batteries produced by a list of specified entities. This list includes several prominent Chinese battery manufacturers, such as Contemporary Amperex Technology Company, Limited (CATL) and BYD Company, Limited, as well as any entity identified under the Uyghur Forced Labor Prevention Act, as a Chinese military company, or on the Commerce Department's Entity List. The prohibition also extends to subsidiaries or successors of these identified entities. The Secretary of Homeland Security can issue waivers to this prohibition under specific circumstances. One waiver condition allows procurement if the batteries pose no national security, data, or infrastructure risk and no comparable alternative exists from non-prohibited entities. Another waiver permits procurement solely for research, evaluation, training, testing, or analysis purposes. Additionally, the bill mandates that the Secretary submit a report within 180 days of enactment, detailing the anticipated impacts on DHS missions and costs across its various components due to these new procurement restrictions.
