Definition & Explanation

Before accepting dangerous goods for carriage, a carrier or freight forwarder requires the shipper to provide a declaration for hazardous materials classification – a binding document in which the sender formally confirms the correct classification of the cargo and assumes responsibility for that assessment. The declaration states the proper shipping name, UN number, hazard class, packing group, packaging details, quantity, and any special handling instructions. The applicable regulatory framework depends on the mode of transport: IMDG for sea freight, IATA DGR for air cargo, ADR for road, and RID for rail. An incomplete or inaccurate declaration can lead to refusal of carriage, regulatory fines, or – in the event of an incident – personal liability for the shipper. The document is therefore not merely a formality but the foundation for safe transport planning across all parties involved.
