IMDG Class 9 (Miscellaneous Dangerous Goods)

Catch-all for substances dangerous in transport but not fitting Classes 1-8 (e.g., asbestos, dry ice, lithium batteries, env. hazardous).

In practice

Class 9 'miscellaneous dangerous substances' covers lithium batteries (UN3480/3481), magnetic substances, environmentally hazardous substances, and many specific UN numbers. Lithium-battery fires on container ships are an industry-wide concern; carriers tighten declaration audits.

Regulatory detail & full definition

Lithium batteries (UN 3480, 3481, 3090, 3091) are the most-shipped Class 9 today and have driven major rule changes (state of charge limits, packaging tests). Marine pollutant designation (UN 3082, 3077) also Class 9. Common in containers; segregation more relaxed than Classes 1-8.
