The rules are especially strict for air transport due to the elevated fire risks associated with the confined environment and altitude. In the following sections, we highlight
Additional Air Restrictions or Requirements: • Damaged, defective, or recalled lithium batteries are forbidden from air transport. See page 7 for information on DDR batteries. • These shipments are forbidden to be transported as cargo on passenger aircraft (column 9 of the HMT - § 172.101).
You will encounter two main types when transporting lithium batteries by air: lithium ion batteries and lithium metal batteries. Lithium ion batteries, often used in consumer electronics like laptops and smartphones, are rechargeable and have a typical energy density of 160–270Wh/kg for NMC Lithium battery and 180–230Wh/kg for LCO Lithium battery.
If not inside a device like a smartphone, the batteries must be in a hard cased container. There are restrictions as to how many lithium-ion batteries can be sent within separate containers by air. Only a maximum of four can be sent, with two per container, and each battery must have a rating of below 100 watts per hour.
