Key Takeaways
- UN2794 (Class 8 Corrosive) batteries must be protected against short circuits and packed with acid-absorbent liner materials under IATA PI 870 or IMDG P801.
- Liquid chemical imports into Thailand must be screened by CAS Number against the Ministry of Industry Hazardous Substance List (Types 1, 2, or 3).
- Cryogenic Dry Shippers containing fully absorbed liquid nitrogen with no free liquid are exempted from Dangerous Goods regulations under IATA Special Provision A152.
1. Transporting UN2794 Wet Acid Batteries (Class 8)
Lead-acid automotive and industrial batteries filled with sulfuric acid fall under UN2794, Class 8 (Corrosive):
- Terminal Protection & Upright Securing: Terminals must be insulated against short circuits and secured upright inside acid-resistant packaging.
- Comparison with UN2800: AGM or gel batteries that pass vibration and pressure differential tests with zero leakage are classified under UN2800 (Non-spillable).
2. International Liquid Chemicals & LN2 Cryogenic Transport
International transport of liquid chemicals in ISO Tanks, IBC totes, or UN drums requires CAS Number screening with the Thai Department of Industrial Works (DIW) via NSW. For biological or cryogenic shipments using liquid nitrogen (LN2 transport), insulated Vapor Dry Shippers that absorb all free liquid nitrogen qualify under IATA Special Provision A152.
