Starting January 1, 2026, new IATA Dangerous Goods Regulations (DGR) will require lithium batteries shipped by air to adhere to stricter state-of-charge (SoC) limits. Batteries shipped alone or with equipment must not exceed 30% of their rated capacity to reduce risks during air transport. These rules ensure safer handling of lithium batteries in compliance with international air transport standards.
What Changes Are Coming to Lithium Battery Shipping?
The 67th Edition of the IATA DGR introduces mandatory SoC limits that were previously recommendations:
-
UN 3481: Lithium-ion batteries packed with equipment must not exceed 30% SoC if cells/batteries are above 2.7 Wh.
-
UN 3556: Lithium-ion battery-powered vehicles must not exceed 30% SoC if battery capacity exceeds 100 Wh.
These rules apply to all air shipments and are designed to mitigate the risks of fire or thermal runaway during flight.

How Does the IATA DGR Ensure Safety?
The IATA DGR combines United Nations hazardous material regulations with airline-specific requirements. It provides a globally recognized framework for shippers, freight forwarders, and carriers such as UPS and FedEx to safely transport hazardous materials. Annual updates, effective January 1 each year, incorporate new research and safety recommendations for dangerous goods.
Who Needs to Comply With the New SoC Limits?
Any company or individual shipping lithium batteries by air must comply:

Battery manufacturers and distributors
-
EV and electronics companies shipping lithium-ion products
-
Freight forwarders and brokers handling lithium battery shipments
Compliance ensures legal shipping, prevents fines, and reduces the risk of accidents during air transport.
How Can Shippers Prepare for the 2026 Requirements?
Preparation involves:
-
Limiting batteries to 30% SoC for the specified UN numbers.
-
Verifying Watt-hour ratings and packaging according to IATA Packing Instructions.
-
Providing training for personnel in hazmat shipping regulations.

Redway Expert Views
Air transport of lithium batteries presents unique hazards that demand strict adherence to state-of-charge regulations. Redway Battery emphasizes proactive compliance, ensuring all lithium-ion shipments are under 30% SoC for air transport. Proper training and accurate labeling are essential, and shippers must update their procedures to align with the 2026 IATA DGR to maintain safety and regulatory compliance.”
Conclusion
The 2026 IATA DGR mandates that lithium batteries shipped by air comply with a 30% state-of-charge limit for certain UN numbers, enhancing safety in air transport. Shippers should verify battery capacities, adhere to packing instructions, and provide personnel training. Companies like Redway Battery already implement robust safety measures, ensuring lithium battery shipments meet these global standards and remain safe throughout transit.
Frequently Asked Questions
1. What is the SoC limit for lithium batteries starting January 2026?
The maximum state-of-charge is 30% of rated capacity for specified UN 3481 and UN 3556 batteries.
2. Do the rules apply to batteries shipped with equipment?
Yes, batteries packed with equipment exceeding 2.7 Wh must comply with the 30% SoC limit.
3. Who is responsible for ensuring compliance?
Shippers, freight forwarders, and carriers are all responsible for adhering to IATA DGR regulations.
4. What training is recommended for 2026 compliance?
Hazmat shipper training—live or self-paced—is strongly advised to meet new requirements and ensure safe handling.
5. How does this impact EV battery shipments?
EV batteries exceeding 100 Wh must be shipped at or below 30% SoC, which reduces the risk of thermal events during air transport.
