You ask whether lithium batteries treated as described in the scenario below would still be considered DDR lithium batteries. Specifically, you describe a lithium battery that has been processed—prior to transportation—to no longer have the potential to: • Be electrically charged. • Hold any electrical charge or be capable of being charged. • Be electrically connected to equipment (e.g., electrical plugs have been destroyed). • Hold electrolyte, flammable, or explosive liquids, or gases. • Have the operational ability to provide power to equipment. • Present a dangerous evolution of heat, fire, or be short circuited. You further add that the batteries have been tested in accordance with Resource Conservation and Recovery Act (RCRA) testing (Toxicity Characteristic Leaching Procedure (TCLP), and ignitability) with results showing no flash point below 140 degrees F, and no TCLP metals detected. As specified in § 173.22 of the HMR, it is the shipper’s responsibility to properly class and describe a hazardous material in accordance with Parts 172 and 173 of the HMR. This Office generally does not perform that function. However, it is the opinion of this Office that the lithium batteries processed in the manner you describe would not be considered a battery nor a DDR battery. A lithium battery or cell is not subject to the HMR, if it does not meet the definition of a <<>> battery or cell in Section 38.3.2.2 of the UN Manual of Tests and Criteria. Once again, it is the responsibility of the shipper to determine whether any materials or contents that remain meet any HMR criteria for hazardous materials. I hope you find this information is helpful. Please contact us if we can be of further assistance.
