DG (Dangerous Goods)

Dangerous Goods (DG) are substances or articles that pose a risk to health, safety, property, or the environment during transport. They are regulated by international codes specific to each transport mode: IATA DGR for air, IMDG Code for sea, ADR for road (Europe), and RID for rail.

DG is classified into 9 main classes: 1-Explosives, 2-Gases, 3-Flammable Liquids, 4-Flammable Solids, 5-Oxidisers, 6-Toxic/Infectious, 7-Radioactive, 8-Corrosive, 9-Miscellaneous Hazardous. Each substance has a UN number, a Proper Shipping Name, a packing group (I, II, III), and segregation rules with other DG classes.

Shippers must complete a Shipper's Declaration for Dangerous Goods; carriers must accept only DG that complies; and operational staff (including GHA acceptance teams) must hold valid DG certifications. Non-compliance can result in fatal accidents and criminal liability.
