Chapter 2.0 – Introduction

2.0.2 UN Numbers and Proper Shipping Names

  2.0.2.2 The existing first paragraph is replaced by the following:

  • "2.0.2.2 Dangerous goods commonly transported are listed in the Dangerous Goods List in chapter 3.2. Where an article or substance is specifically listed by name, it shall be identified in transport by the proper shipping name in the Dangerous Goods List. Such substances may contain technical impurities (for example those deriving from the production process) or additives for stability or other purposes that do not affect their classification. However, a substance listed by name containing technical impurities or additives for stability or other purposes affecting its classification shall be considered a mixture or solution (see 2.0.2.5). For dangerous goods not specifically listed by name "generic" or "not otherwise specified" entries are provided (see 2.0.2.7) to identify the article or substance in transport.".

  2.0.2.5 The existing paragraph is replaced by the following:

  • "2.0.2.5 A mixture or solution composed of a single predominant substance identified by name in the Dangerous Goods List and one or more substances not subject to the provisions of this Code and/or traces of one or more substances identified by name in the Dangerous Goods List, shall be assigned the UN number and proper shipping name of the predominant substance named in the Dangerous Goods List unless:

    • .1 The mixture or solution is identified by name in the Dangerous Goods List;

    • .2 The name and description of the substance named in the Dangerous Goods List specifically indicate that they apply only to the pure substance;

    • .3 The hazard class or division, subsidiary risk(s), packing group, or physical state of the mixture or solution is different from that of the substance named in the Dangerous Goods List; or

    • .4 The hazard characteristics and properties of the mixture or solution necessitate emergency response measures that are different from those required for the substance identified by name in the Dangerous Goods List.

    In those other cases, except the one described in (.1), the mixture or solution shall be treated as a dangerous substance not specifically listed by name in the Dangerous Goods List.".

  2.0.2.10 Add a new paragraph 2.0.2.10 with the following:

  • "2.0.2.10 A mixture or solution meeting the classification criteria of this Code that is not identified by name in the Dangerous Goods List and that is composed of two or more dangerous goods shall be assigned to an entry that has the proper shipping name, description, hazard class or division, subsidiary risk(s) and packing group that most precisely describe the mixture or solution.".

2.0.3 Classification of substances, mixtures and solutions with multiple hazards (precedence of hazards characteristics)

  2.0.3.5 At the end of the paragraph, insert the following new sentence:

  • "For radioactive material in excepted packages, special provision 290 of chapter 3.3 applies.".
