Dangerous Goods Declaration
A mandatory declaration for shipping hazardous materials by sea, air, or land.
What It Is
A Dangerous Goods Declaration (DGD) is a formal document that identifies hazardous materials in a shipment and provides handling instructions to carriers, port authorities, and emergency responders. It follows the UN Recommendations on the Transport of Dangerous Goods and the relevant modal regulations (IMDG Code for sea, IATA DGR for air).
When It's Required
Required whenever a shipment contains goods classified under the UN dangerous goods system:
- Sea freight — IMDG Code compliance required
- Air freight — IATA Dangerous Goods Regulations (DGR) compliance required
- Road/rail — ADR/RID regulations apply (Europe), DOT 49 CFR (US)
Failure to declare dangerous goods can result in severe penalties, cargo refusal, and criminal liability.
