International Maritime Dangerous Goods Code

The IMO rulebook for shipping dangerous goods by sea.

In practice

Covers classification, packaging, marking, labelling, documentation, stowage, and segregation on the vessel. Updated every two years. Ocean DG declarations must follow it, and the carrier's DG desk checks every booking against it.
