Hazard labels appear on packages, overpacks, and freight containers the moment a consignment includes dangerous goods. Standardized pictograms, colours, and hazard class numbers tell carriers, warehouse staff, and emergency responders at a glance what type of risk they are dealing with—explosives, flammables, toxics, radioactive materials, corrosives, and more. The governing framework depends on the mode of transport: ADR for road, the IMDG Code for sea, IATA DGR for air, and RID for rail. Correct labelling is the shipper's legal obligation. Missing or incorrect labels can result in shipment refusal, regulatory fines, and civil liability.
