Dangerous goods: classes and documents
Many ordinary products are dangerous goods in transport: paints, perfumes, batteries, aerosols, some chemicals. They can travel, but only when classified, packed, marked and declared correctly.

The nine classes
| Class 1 | Explosives |
|---|---|
| Class 2 | Gases |
| Class 3 | Flammable liquids |
| Class 4 | Flammable solids and substances that react dangerously |
| Class 5 | Oxidising substances and organic peroxides |
| Class 6 | Toxic and infectious substances |
| Class 7 | Radioactive material |
| Class 8 | Corrosives |
| Class 9 | Miscellaneous dangerous goods, including lithium batteries |
What a shipment needs
- Safety data sheet (SDS) - from the manufacturer. It shows the classification.
- UN number and proper shipping name - the four-digit number that identifies the substance.
- Packing group - I, II or III, for high, medium or low danger, where the class uses them.
- Approved packaging, marks and labels - as the rules set out for the substance.
- Dangerous goods declaration - signed by the shipper, travelling with the shipment.
Sea and air are different
By sea, dangerous goods travel under the IMDG Code. By air, they travel under the IATA Dangerous Goods Regulations, which are stricter: some goods that can go by sea cannot fly at all, and quantity limits are lower. Carriers, vessels and airlines can also set their own restrictions above the rules.
