Definition & Explanation
Once a shipment has been identified as dangerous goods, the correct shipping name, UN number, and hazard class must be taken from an authoritative reference: the dangerous goods nomenclature directory. This directory lists all dangerous goods approved for transport, together with their proper shipping name, UN number, hazard class, packing group, and the applicable requirements under ADR (road), RID (rail), IMDG Code (sea), or IATA DGR (air). Dangerous goods safety advisors and freight forwarders consult it routinely to verify classification and to meet packing, marking, and documentation obligations. An incorrect or missing shipping name is a serious violation: it can lead to transport prohibitions, fines, and – should an incident occur – significant liability exposure. The directory is updated at regular intervals, making it essential to always work from the current edition of the relevant regulatory instrument.
