IATA Publishes the 67th Edition of the Dangerous Goods Regulations

The new edition of the Dangerous Goods Regulations (IATA DGR), in force since 1 January 2026, includes significant changes in classification, packaging, and transport, particularly for batteries and hybrid vehicles.

The 67th edition of the Regulations, published by the International Air Transport Association (IATA), introduces key modifications to enhance safety in the air transport of dangerous goods.

The most relevant changes are as follows:

• Inclusion of new IMP codes for vehicle transport.
• Adjustments to protocols for spare batteries and power banks carried in the cabin.
• Update of Table 2.3.A to reinforce safety protocols applicable to battery-powered devices carried in the cabin..
• Inclusion of the definition of Safety Data Sheet (SDS) in Appendix A, and Appendix B.4 expands information on its purpose and basic principles.

As a new feature, Appendix H is incorporated, anticipating technical changes based on the 24th revised edition of the UN Recommendations on the Transport of Dangerous Goods:

• A classification guide for hybrid batteries is introduced, requiring them to be considered under the applicable provisions for lithium ion batteries. The term “hybrid” is added to the entries corresponding to vehicles powered by flammable gas or liquid under UN number 3166 to clarify their classification. The entry UN 3536 is revised and new references are added for batteries installed in cargo units, including lithium metal and sodium ion batteries.
• New entries UN 3563 (lithium metal batteries installed in cargo units) and UN 3564(sodium ion batteries installed in cargo units) are incorporated.
• New entries for chlorophenols (UN 3561 and UN 3562) are added, with different hazard levels (corrosive/toxic).
• Special Provision A236 is introduced for magnetic resonance imaging (MRI) equipment, allowing exemptions under specific conditions.
• An exemption is added for the transport of blood and blood components intended for transfusions, under defined requirements.

Additionally, new restrictions affecting the transport of batteries also come into force:

• State of Charge (SoC) limit: for vehicles with lithium ion, lithium metal or sodium ion batteries (UN 3556, 3557 and 3558), the SoC may not exceed 30% of the rated capacity nor 25% of the indicated capacity at the time of transport.
• Lithium ion batteries with a power rating above 2.7 Wh must not exceed a 30% charge when transported with equipment. If this limit is exceeded, written approval is required, and the shipment can only be transported on cargo aircraft.

Although these adjustments will be fully applied in 2027, companies are advised to anticipate compliance by adjusting packaging and labelling according to the new UN codes, updating operational manuals and checklists, verifying country and operator specific variations, and ensuring personnel training in the requirements of the 67th edition.

Additionally, IATA has published Addendum 1 corresponding to the 67th edition, introducing editorial corrections and clarifications in various tables and provisions of the regulations. Although it does not modify the main technical requirements, operators and shippers are encouraged to review these details to ensure correct application of the current DGR.
