Sea and air carriers accept dangerous goods only when they are correctly classified, packed, marked and documented. The rules are the IMDG Code for sea freight and the IATA Dangerous Goods Regulations for air.
Start with the safety data sheet
Ask your supplier for the current safety data sheet (SDS). Section 14 gives the transport information: UN number, proper shipping name, hazard class and packing group. Without it, no carrier can assess your booking.
What carriers will check
- UN-approved packaging suitable for the substance and packing group
- Hazard labels and marks on every package
- A dangerous goods declaration signed by trained staff
- Segregation from incompatible cargo in the container or aircraft hold
Air or sea?
Some substances are forbidden on passenger aircraft or limited to cargo aircraft only, and quantity limits per package apply. Sea freight accepts a wider range of dangerous goods but needs advance carrier approval. Plan extra lead time for DG bookings on either mode.
General guidance only, not legal or customs advice. Regulations change; confirm current requirements for your goods before shipping.
