# Labeling and Documentation for Dangerous Goods

*Last updated: 2026-06-25*

> Freight forwarders, shippers, and carriers are legally required to mark hazardous goods with standardized labels, placards, and hazard markings, and to provide the prescribed transport documents.

Freight forwarders, shippers, and carriers are legally required to mark hazardous goods with standardized labels, placards, and hazard markings, and to provide the prescribed transport documents. Requirements vary by mode: road transport falls under ADR, rail under RID, sea freight under the IMDG Code, and air cargo under the IATA Dangerous Goods Regulations (DGR). The markings allow authorities, emergency responders, and all supply chain parties to identify the hazard class, UN number, and packing group at a glance – information that can be critical in an emergency. Errors in labeling or documentation routinely result in loading bans, shipment holds, and substantial fines. This is distinct from product labeling under chemical classification law (CLP/GHS), which applies to consumer packaging at the point of sale and imposes different requirements from those of transport law.
