Class 8 — Corrosive substances

Summary

Liquids or solids that destroy living tissue or damage materials. Lead-acid and wet-cell batteries fall here; sealed lithium batteries are Class 9.

Packing / quantity notes

Packing Group I (severe corrosion): forbidden in passenger aircraft. PG II (moderate corrosion): cargo only with operator approval. PG III (mild): may be accepted in passenger baggage in limited quantities per IATA Table 2.3.A. Most consumer items containing dilute acid (non-spillable lead-acid sealed batteries, small quantities of vinegar-grade acetic acid) qualify for the limited-quantity exemption; concentrated drain cleaners, lab-grade mineral acids, and bulk hypochlorite do not.

Examples

• Car / motorcycle wet-cell batteries
• Drain-cleaner liquids
