Effective Jan 1, 2020 – The Department of Transportation (DOT) published rule, 83 Fed. Reg. 60970 which requires Test Summaries (TS) to be provided under the guidelines of Lithium Battery UN38.3.

What this means to you as a battery manufacturer in the WERCSmart program

Battery manufacturers are required to provide a Lithium Battery Test Summary (TS) as part of your WERCSmart product registration. Failure to do so will result in product suspension until a Lithium Battery (TS) is provided and approved.

Impact to your downstream partners

If your battery is still being sold in the marketplace, your downstream partners are affected. Downstream partners that you sell products to as part of their Battery-Containing Products (BCP), will also undergo product suspension until your Lithium Battery Test Summary (TS) is provided and approved.


Once approved, WERCSmart will automatically assign it to your downstream partner’s product registration. No further action will be required for BCP suppliers to comply with UN 38.3, however BCP’s suppliers are encouraged to continue working with your downstream partners in order to meet product registration requirements.
