32 UN Classes, UN Divisions and Categories of dangerous goods

The UN Class, Division or Category of particular dangerous goods for the purposes of this Regulation is—

(a) if a determination under section 22(1)(b) that the goods are of a particular UN Class, Division or Category is in effect in relation to the goods—the Class, Division or Category specified in the determination, or

(b) otherwise—the Class, Division or Category determined for the goods in accordance with the ADG Code.

Note 1—

Under the UN classification system there are 9 classes of dangerous goods. Under that system some Classes are further divided into Divisions and some Divisions are divided into Categories.

**Example—**UN Division 6.2 infectious substances is divided into—

(a) Category A—substances transported in a form that, if exposure occurs, can cause permanent disability or life-threatening or fatal disease to humans or animals, and

(b) Category B—others.

Note 2—

Under the ADG Code, if particular dangerous goods are listed in the Dangerous Goods List, their UN Class or Division is that listed in column 2 of the list opposite the name and description of the goods, unless Chapter 3.3 of the ADG Code provides for the goods to be assigned to a different Class or Division. If applicable, Chapter 2 of the ADG Code describes how the UN Category of dangerous goods is to be determined. Once again the Category may be changed under Chapter 3.3 of the ADG Code.
