Is It Safe to Ship Lithium Batteries by Air?
Direct answer
Yes, if shipped as cargo with a current UN38.3 test summary and Class 9 lithium labeling. Loose cells over 100Wh cannot fly on passenger planes, and air freight costs 3-5× sea per kg. Most B2B battery orders move by sea; air is only worth it for urgent samples or <50kg prototypes.
Air vs sea at a glance
| Factor | Air | Sea |
|---|---|---|
| Transit | 3-7 days | 25-45 days |
| Cost/kg | $4-8 | $0.80-1.50 |
| Labeling | Class 9 + UN38.3 | Class 9 + UN38.3 |
When air makes sense
- Pre-production samples (1-4 units) to hit a trade-show deadline.
- Emergency replacement for a downed system.
- High-value, low-weight prototype under 100Wh/piece.
For full container loads, use DDP sea . details in the DDP shipping guide. Every Luchu Energy shipment includes the UN38.3 summary.
Frequently asked questions
Can LiFePO4 batteries fly on passenger planes?
Only as cargo, and only with a valid UN38.3 test summary and Class 9 lithium battery labeling. Passenger-carry of loose cells above 100Wh is banned; contained battery packs under 100Wh per piece may be checked with airline approval. Most B2B shipments move by sea because air freight for batteries costs 3-5× more per kg.
