How does the IMDG code affect hazmat packaging?

• A. It governs air transport packaging only.
• B. It governs inland waterway shipments packaging only.
• C. It governs packaging for road transport.
• D. It governs sea transport packaging, labeling, and documentation for shipments by sea.

Answer: (D)

The IMDG Code governs packaging for sea transport of dangerous goods, guiding how packaging must be designed, tested, marked, and what documentation must accompany shipments. For hazmat headed by sea, packaging typically must be UN specification and have been tested for the specific danger class and packing group, so it can withstand the conditions of marine handling, moisture, salt exposure, and stacking. Each package needs clear, correct markings with the UN packaging mark and the appropriate hazard labeling that communicates the danger to handlers, stowage teams, and ship crews. Documentation is a key part as well: you need the shipper’s declaration for dangerous goods and the proper shipping information (name, UN number, class, packing group, quantity) on the sea shipment documents. This focus is specific to sea transport; other modes of transport follow different regulations and codes for packaging, labeling, and documentation.
