The United States Coast Guard has published a helpful compliance resource, Lithium Battery Guide for Shippers.
The publication aims to assist shippers to safely package lithium cells and batteries for transport by all modes, including vessel shipments, with new regulatory requirements based on cell or battery configuration as well as Watt-hour (Wh) rating.
As described in the guide, the transport of lithium cells and batteries via vessel can be subject to both the domestic regulations and the International Code for the International Maritime Dangerous Goods (IMDG) that may require additional actions. Both publications should be consulted based on shipment route.
