Definition & Explanation

Freight forwarders, dangerous goods safety advisers and warehouse operators work daily with material identification systems for dangerous goods – standardised frameworks that classify, label and document hazardous substances unambiguously throughout the transport chain. The core elements are UN numbers for substance identification, GHS hazard pictograms, and the modal classification schemes under ADR (road), the IMDG Code (sea), IATA DGR (air) and RID (rail). Every shipment must carry the correct markings on its packaging, the transport unit and all accompanying documents – a requirement that is internationally binding across all modes. The system serves three practical purposes: preventing mishandling, giving emergency responders immediate information at the scene, and clearly allocating liability among all parties involved. In-house warehouse labelling conventions may complement these frameworks but cannot substitute for them.
