In this rulemaking, PHMSA would amend the Hazardous Materials Regulations (HMR) by updating and revising the transportation requirements for lithium cells or batteries determined to be damaged, defective, or recalled (DDR). This rulemaking would be informed by ongoing efforts to improve alignment of the domestic hazardous materials transportation requirements with provisions found in international standards regarding DDR lithium cells or batteries, where appropriate. Additionally, this rulemaking would update the authorized packaging requirements for DDR lithium cells and batteries by, for example, proposing to adopt into the HMR provisions from certain special permits issued to U.S. stakeholders allowing specially designed packaging for transport of lithium cells and batteries. PHMSA will also address the transportation requirements of electric vehicles with DDR lithium batteries installed.
