The International Maritime Organization (IMO) has recently published amendments to the International Maritime Dangerous Goods Code (IMDG Code) – Amendment 42-24, which will become mandatory from January 1, 2026. The revisions include several important updates, particularly regarding transport requirements in the new energy sector. Relevant foreign trade and logistics enterprises must pay close attention.

Key Revisions:

1. New Transport Requirements for Sodium-Ion Batteries
   To accommodate the development of the new energy industry, the amendments have, for the first time, incorporated sodium-ion batteries into the regulatory framework:

   • New UN 3551: Sodium-ion batteries (containing organic electrolyte)

   • New UN 3552: Sodium-ion batteries installed in equipment
     This revision provides clear transport standards for the international trade of sodium-ion batteries.

2. Improvements to Existing Dangerous Goods Regulations

   • Carbon material (UN 1361): Special exemption clauses have been removed, with new special provisions added to clarify requirements for weathering, transport, and packaging.

   • Lithium battery-powered vehicles: A new dedicated packaging instruction, P912, has been introduced, applicable to vehicles powered by lithium batteries (UN 3556) and lithium metal batteries (UN 3557).

3. Updates to Documentation and Marking Requirements

   • Transport documents: A new clause requires exempted goods to be accompanied by supporting documentation.

   • Marking and placarding: Existing lithium battery marking provisions have been extended to the newly added sodium-ion batteries.

Impacts and Recommendations for Enterprises:

1. Timely Update of Operational Procedures
   It is recommended that relevant enterprises complete the following before January 2026:

   • Revision of internal operational procedures

   • Staff training

   • Updates to packaging and documentation systems

2. Focus on New Energy Products
   Enterprises involved in lithium-ion batteries, sodium-ion batteries, and related products should:

   • Conduct transport assessments in advance

   • Prepare packaging solutions compliant with the new regulations

   • Update transport document templates

3. Strengthen Compliance Management

   • Establish a compliance review mechanism for product transportation

   • Maintain close communication with freight forwarders and shipping companies

   • Stay informed about implementation details at various ports

The implementation of these amendments will further standardize the maritime transport of dangerous goods and enhance transport safety. Relevant enterprises are advised to prepare as early as possible to ensure full compliance before the mandatory effective date.
