What is the IMDG Code and what type of cargo does it govern?

• A. International Marine Navigation Code; governs route planning
• B. International Labour Organization (ILO)
• C. United Nations Environment Programme (UNEP)
• D. International Maritime Dangerous Goods Code; governs transport of hazardous goods, including classification, packaging, labeling, segregation, and documentation.

Answer: (D)

The key idea is that the IMDG Code is a standard for safe handling and transport of dangerous goods by sea. It’s an International Maritime Organization code that sets out how hazardous cargo must be classified, packaged, labeled/marked, segregated from incompatible goods, and documented for carriage. This means ships, crews, and ports follow consistent rules to minimize risks to people and the environment when such cargo is moved by sea. The others aren’t correct because they refer to a non-existent “International Marine Navigation Code” (which would be about route planning) or to organizations (ILO, UNEP) rather than a transport regulation for hazardous goods.
