11 UN classes, divisions and categories of dangerous goods
For this regulation, a UN class, UN division or UN category of dangerous goods is—
if a determination under section 29 (1) (b) (Determinations—dangerous goods and packaging) that the goods are of a stated UN class, division or category is in effect—the stated class, division or category; or
if there is no determination under section 29 (1) (b) in effect in relation to the goods—the class, division or category determined for the goods in accordance with the ADG code.
