Cargo Container Guidelines - Lithium-ion batteries Publications Steamship Mutual Published: May 11, 2023 Contact author Download article pdf Lithium-ion batteries are a growing cause for concern to the marine industry due to their high energy densities and pose a high risk of fire due to thermal runaway.  The consequences of such an event can be severe resulting in serious damage to ship, environment, cargo and crew.  The industry has also recognised the enhanced risk from the carriage of lithium-ion batteries as cargo or as components within a wide range of consumer products.  The CINS network consisting of various stakeholders in the supply chain, including the International Group of P&I Clubs, International Cargo Handling Coordination Association (ICHCA), Shipowners, TT Club and other Maritime Industry’s experts have produced a helpful Guideline to address the risks associated with the carriage of Lithium-ion batteries in containers. As stated in the Guideline , existing standards of safety and regulation have fallen short of addressing the serious risks associated with the carriage of Lithium-ion batteries. Members’ attention is drawn to this useful Guideline. According to the Guidelines  the primary concern associated with the carriage of Lithium-Ion batteries is the thermal runway, a process that can lead to an uncontrolled propagation of heat within the battery assembly, with resulting fires.  The Guidelines are intended to highlight the risks that Lithium-Ion batteries can present, providing guidance and suggestions for identifying the risks and ensuring safe carriage of the batteries.  While the Guideline addresses the general classification and regulation for the testing and carriage of lithium-ion batteries, as defined in the UNECE 2021 testing criteria and the IMDG Class 9 hazardous material classification, the Guideline also details appropriate additional measures that should be undertaken by the industry stakeholders.
