How to Transport Lithium Batteries on a Plane？
Shipping lithium batteries by air as cargo is complex and requires strict compliance with the IATA Dangerous Goods Regulations (DGR) and Battery Shipping Regulations (BSR)—the 2026 editions have introduced several important changes.
Key 2026 Regulatory Updates for Shippers
Special Rules for Large Batteries (>35 kg)
Very large lithium batteries (weighing more than 35 kg), such as those used in electric vehicles or industrial storage, require special approval from the civil aviation authority before they can be shipped by air.
- Testing Required: These batteries must pass specific tests covering transport conditions, thermal safety (thermal runaway and propagation), and packaging performance.
- Standard: The testing must follow standards like the Specific Requirements for the Transport of Dangerous Goods by Air — Test for Large Lithium Batteries (MH/T 1086-2026).
How to Ship Batteries Correctly: Step-by-Step
- Classify Your Batteries: Determine if they are Lithium Ion (rechargeable, UN 3480) or Lithium Metal (non-rechargeable, UN 3090).
- Check the State of Charge (SoC): Ensure batteries are within the latest charge limits (set to become stricter in 2026 for batteries packed with equipment).
- Use Proper Packaging: Follow the relevant IATA Packing Instruction (PI) – e.g., PI 965, PI 966, PI 967. The IATA Lithium Battery Shipping Regulations (LBSG) guide provides step-by-step visual examples.
- Mark and Label Packages: Apply the correct lithium battery handling mark with the appropriate UN number.
- Complete Documentation: Prepare the Shipper’s Declaration for Dangerous Goods (unless shipping under specific exceptions like Section II). A new shipper compliance checklist is also required for all battery shipments.
- Use a Qualified Forwarder: Work with a freight forwarder trained and certified in handling dangerous goods by air.
Summary Comparison
| Aspect | Passenger (Personal Items) | Commercial Shipper (Cargo) |
|---|---|---|
| Core Rule | Spare batteries in carry-on only | Must comply with IATA DGR/BSR |
| Key 2026 Change | No charging devices in-flight | Stricter charge limits + shipper checklist |
| Large Batteries (>35kg) | Not applicable | Requires special authority approval & testing |
| Documentation | None (for personal use) | Shipper’s Declaration + new compliance checklist |
Final Guidance
The regulations governing air transport of lithium batteries are constantly evolving. For the most current requirements:
- Passengers: Always check your specific airline’s policy before flying, as they may have additional restrictions.
- Shippers: Reference the latest IATA Dangerous Goods Regulations (67th Edition, effective Jan 1, 2026) and the IATA Lithium Battery Shipping Regulations (LBSG). Use the new shipper compliance checklist introduced in 2026.
Mis-declaring or improperly packing lithium batteries is a serious safety violation and can result in significant fines. When in doubt, consult a certified dangerous goods professional.
