The rules for classification are very widely defined, but some, for example most medicines and cosmetics, do not have the hazardous properties that would bring them within scope of the requirements, and those that do are usually carried in very small receptacles, allowing at least partial exemption from the requirements (either limited quantities or limited loads)

Consignors have a duty to identify the hazards of the goods they intend to transport. There are nine classes, some with divisions, as follows.

All relevant  hazards have to be determined. There is a hierarchy of classification and there are rules about choosing the most appropriate entry and hence UN number.

Once a UN number and proper shipping name have been assigned, some substances with the same name will have different degrees of danger (for example flash point). This is reflected in the “packing group” (PG), Where a substance has been classified from “first principles”, its PG will be determined by its properties.

Proper shipping names may also be qualified by the addition of the terms such as 'SOLUTION'; 'LIQUID'; 'SOLID'; 'MOLTEN', 'STABILIZED'.
