> When a shipper identifies a product as potentially subject to dangerous goods regulations, the assessment procedure begins.

When a shipper identifies a product as potentially subject to dangerous goods regulations, the assessment procedure begins. The substance or article must be classified under the applicable modal frameworks – ADR for road, the IMDG Code for sea, and IATA DGR for air – with the correct UN number, hazard class, and packing group assigned accordingly. Packaging requirements, labeling, marking, and transport documentation are then determined on that basis. Primary responsibility rests with the shipper, but freight forwarders, carriers, and customs authorities all verify compliance as part of their own control obligations. Errors in the assessment – a misclassified hazard class, a missing Safety Data Sheet reference, or an incorrect packing group – can result in transport bans, fines, or, in serious cases, accidents.
