The moment dangerous goods are tendered for carriage, hazardous goods labelling standards take effect, prescribing exactly how hazards must be communicated visually through labels, hazard diamonds, markings and placards. Required elements include the applicable UN number, proper shipping name, hazard pictograms and, where relevant, the packing group. Requirements differ by transport mode: the IMDG Code governs sea freight, IATA DGR covers air, ADR applies to road and RID to rail. Correct labelling is a condition of carriage and allows everyone in the chain—from warehouse staff to emergency responders—to identify risks at a glance, regardless of language. Incorrect or missing labelling can result in consignment rejection, regulatory fines or shipper liability in the event of an incident.
