  • (2) For the purposes of this section, a proof of classification is

    • (a) a test report;

    • (b) a lab report; or

    • (c) a document that explains how the dangerous goods were classified.

  • (3) A proof of classification must include the following information:

    • (a) the date on which the dangerous goods were classified;

    • (b) if applicable, the technical name of the dangerous goods;

    • (c) the classification of the dangerous goods; and

    • (d) if applicable, the classification method used under this Part or under Chapter 2 of the UN Recommendations.

  • SOR/2014-152, s. 12

Classifying Substances That Are Listed by Name in Schedule 1

 If a name of dangerous goods is shown as a shipping name in column 2 of Schedule 1, that name must be used as the shipping name. That shipping name and the corresponding data for that shipping name in columns 1, 3 and 4 of Schedule 1 must be used as the classification of the dangerous goods.

Classifying Substances That Are Included in Only One Class and One Packing Group

 If, in accordance with the criteria and tests in this Part, a substance is included in only one class and one packing group, the substance is dangerous goods and the shipping name in column 2 of Schedule 1 that most precisely describes the dangerous goods and that is most consistent with the class and the packing group determined by the criteria and tests must be selected as the shipping name. That shipping name and the corresponding data for that shipping name in columns 1, 3 and 4 of Schedule 1 must be used as the classification of the dangerous goods.

Classifying Substances That Are Included in More Than One Class or Packing Group

 If, in accordance with the criteria and tests in this Part, a substance meets the criteria for inclusion in more than one class or packing group, the substance is dangerous goods and 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; and

  • (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.

  • SOR/2008-34, s. 29(E)

Descriptive Text Following a Shipping Name

 When applying section 2.4 or 2.5, the descriptive text written in lower case letters following a shipping name must be used in determining the shipping name that most precisely describes the dangerous goods.

  • SOR/2008-34, s. 30

Classifying a Mixture or Solution

 A mixture or solution of substances that are not dangerous goods and one substance that is dangerous goods and that is listed by name in Schedule 1 has the classification shown for the dangerous goods in that Schedule if the mixture or solution is still dangerous goods in accordance with paragraph 2.1(a) and the mixture or solution is not identified by a shipping name in Schedule 1. However, if the classification for the dangerous goods does not precisely describe the mixture or solution but the mixture or solution meets the criteria in this Part for inclusion in at least one of the 9 classes of dangerous goods, then sections 2.4 and 2.5 must be used to determine its classification.

Marine Pollutants

  •  (1) A substance is a marine pollutant if

    • (a) the letter “P” (marine pollutant) is set out in column 4 of Schedule 3 for the substance; or

    • (b) the substance meets the criteria for classification as a marine pollutant in accordance with section 2.9.3 or chapter 2.10 of the IMDG Code.

    • (c) [Repealed, SOR/2014-306, s. 18]

  • (2) [Repealed, SOR/2014-306, s. 18]

  • (3) [Repealed, SOR/2014-306, s. 18]

  • SOR/2014-306, s. 18

Precedence of Classes

  •  (1) When dangerous goods meet the criteria for inclusion in more than one class but meet the criteria for inclusion in only one of the following classes, that one class is the primary class. The classes are

    • (a) Class 1, Explosives, except for the following dangerous goods for which Class 1 is a subsidiary class:

      • (i) UN3101, ORGANIC PEROXIDE TYPE B, LIQUID,

      • (ii) UN3102, ORGANIC PEROXIDE TYPE B, SOLID,

      • (iii) UN3111, ORGANIC PEROXIDE TYPE B, LIQUID, TEMPERATURE CONTROLLED,

      • (iv) UN3112, ORGANIC PEROXIDE TYPE B, SOLID, TEMPERATURE CONTROLLED,

      • (v) UN3221, SELF-REACTIVE LIQUID TYPE B,

      • (vi) UN3222, SELF-REACTIVE SOLID TYPE B,

      • (vii) UN3231, SELF-REACTIVE LIQUID TYPE B, TEMPERATURE CONTROLLED, and

    • (a) Class 8, Corrosives;

    • (b) Packing Group I due to inhalation toxicity of dusts or mists; and

    • (c) Packing Group III due to oral or dermal toxicity.

  • (3) A consignor must determine the order of precedence among classes that are not listed in subsection (1) in accordance with the following table, except that Class 6.1 takes precedence if a substance is a pesticide under the Pesticide Act and is included in Class 6.1, Packing Group III, and in Class 3, Packing Group III.
