Classifying Substances That Are Included in More Than One Class or Packing Group
The Primary class is shown first, with the subsidiary classes in brackets.
If a substance is included in more than one class or packing group, its classification is determined in the following manner:
(a) the classes in which the dangerous goods are included are ranked in order of precedence in accordance with section 2.8 to determine the primary class and the potential subsidiary class or classes;
(b) the potential packing group is the one with the lowest roman numeral;
(c) the shipping name in column 2 of Schedule 1 that most precisely describes the dangerous goods and for which the corresponding data in columns 1, 3 and 4 are the most consistent with the primary class, the potential subsidiary class or classes and the potential packing group is selected
(d) the shipping name and the corresponding data in columns 1, 3 and 4 of Schedule 1 are used as the classification of the dangerous goods.
See column 3 for the primary and subsidiary classes.
