The International Air Transport Association has recently released an overview of amendments to the IATA Dangerous Goods Regulations (DGR) 66th Edition for 2025. These changes are grounded in the International Civil Aviation Organization’s (ICAO) Technical Instructions 2025-2026 Edition and proposed by IATA’s Dangerous Goods Board. Here’s what you need to know about these new regulations and how they impact your international battery shipping.
Prime Updates in the 2025 Battery Shipping Regulations
1. New UN Numbers for Sodium-Ion Batteries
As more companies explore alternative battery types, regulations have adapted to include sodium-ion batteries, an eco-friendly option. The new 2025 DGR introduces dedicated UN numbers for sodium-ion batteries based on their packaging format:
- UN3551-PI976 for individual sodium-ion cells and batteries
- UN3552-PI977 for batteries packed with equipment
- UN3552-PI978 for batteries installed in equipment
This classification ensures safer handling and standardized practices in air and other transport modes, aiding those managing international battery shipping.
2. Updated Codes for Battery-Powered Vehicles
Battery-powered vehicles, especially those using lithium and sodium-ion batteries, now have distinct classifications under the new codes:
- UN3556 for vehicles powered by lithium-ion batteries
- UN3557 for vehicles powered by lithium metal batteries
- UN3558 for sodium-ion battery-powered vehicles
A noteworthy change is that vehicles under UN3556 and UN3557 will transition away from the UN3171 classification by March 31, 2025. It gives shippers time to adjust to the new requirements without disrupting current operations.
3. Enhanced SoC Restrictions for Lithium Batteries
One of the most significant changes addresses the state-of-charge (SoC) levels, which reduce the risk of thermal runaway. The new regulations expand the SoC limit to below 30% for all lithium-ion products, encompassing various packaging formats:
- PI965: Loose lithium batteries
- PI966: Lithium batteries packed with equipment
- PI967: Lithium batteries installed in equipment
Any lithium batteries with SoC over 30% will require approval from the appropriate authorities, effective by 2025 and fully mandatory by 2026 for batteries over 2.7 Wh.
For example, in scenarios where electronic devices ship with lithium batteries, the SoC for batteries in PI967 should be below 30% or show a battery indicator below 25%.
Additionally, for vehicles under UN3556, UN3557, and UN3558 classifications, SoC should be below 30% or show a battery indicator below 25%. Implementation is recommended for 2025, with mandatory compliance for vehicles with SoC over 100 Wh by 2026.
4. Updated Labeling for Batteries
To streamline labeling, the familiar ‘Lithium Battery Mark’ will now be renamed the ‘Battery Mark’ applicable to lithium and sodium-ion batteries. While the design remains the same, the label must include the correct UN number. This update simplifies labeling for mixed shipments, especially for logistics providers handling multiple battery types.
5. Shipping Exemptions for Sodium-Ion Battery Vehicles
Vehicles equipped with sodium-ion batteries can benefit from certain exemptions, provided their SoC has been reduced to zero and no other restricted goods are present. These updates offer shippers safer and more efficient transport options, reducing regulatory burdens under these specific conditions.
Why This Matters for Battery Shipping in 2025
Adapting to these new battery shipping regulations may seem daunting, but it is essential for managing the risks associated with battery transport. Lower SoC levels reduce the risk of overheating, while clear labeling ensures proper handling and regulatory compliance. Shippers should review these regulations, as they provide greater clarity and enhance safety in the global movement of goods.
