Freight forwarders, shippers, and carriers dealing with dangerous goods must navigate a web of mode-specific regulations: ADR for road, RID for rail, the IMDG Code for sea, and IATA-DGR for air cargo. The conveyance of hazardous materials is not simply a matter of transport – classification, packaging, labelling, and documentation are mandatory prerequisites before a shipment can move. Depending on quantities handled and activities carried out, companies are required to appoint a certified dangerous goods safety adviser. Errors in classification or incomplete documentation can trigger border rejections, substantial fines, or – in serious cases – accidents with significant liability consequences. This framework is distinct from general cargo securing rules, which apply to all freight irrespective of hazard status.
