Lithium batteries in air freight

Lithium metal and lithium ion batteries are dangerous goods with requirements that vary by type, rating, configuration and transport route.

Definition

For air transport, batteries are classified by factors including chemistry, UN number, watt-hour rating or lithium content and configuration: shipped alone, packed with equipment or contained in equipment. These factors determine packing instruction, marking, documentation, quantity limits and possible prohibitions.

Why does it matter?

Damaged, misdeclared or inadequately packed batteries can generate heat, smoke or fire. State and operator variations may add requirements beyond the general IATA DGR provisions.

Key points

  • Confirm battery type, UN number and configuration before quoting and booking.
  • Keep the UN 38.3 test summary and manufacturer data available.
  • Check the current DGR plus state and operator variations.

Practical example

A device contains a rechargeable lithium ion battery. Rating, quantity, packaging and protection of the device are checked before the shipping configuration is confirmed.

Common mistakes

  • Assuming “contained in equipment” means automatically exempt
  • Shipping damaged or recalled batteries as regular new goods
  • Providing only a safety data sheet instead of the required battery data
