Truck carrying chemicals - New Zealand Updates NZS 5433:2020 – Transport of Dangerous Good on LandIn December 2020, the revised version of the New Zealand Standard NZS 5433 Transport of dangerous goods on land was released for immediate use. This supersedes the 2012 standard which was available in two parts and is designed to be incorporated into the Land Transport Rule: Dangerous Goods 2005, and Dangerous Goods Amendments 2010, 2011 and 2016 (the Dangerous Goods Rule).

The revised standard is intended to provide a means of compliance with the Dangerous Goods Rule for the transport of dangerous goods by road and rail in New Zealand (NZ). As NZ imports the majority of its dangerous goods, it has been noted in the standard the importance of also complying with the United Nations Recommendations on the Transport of Dangerous Goods – Model Regulation (UNRTDG), International Air Transport Organisation (IATA), International Civil Aviation Organisation (ICAO) and International Maritime Dangerous Goods Code (IMDG), as well as the relevant New Zealand legislation for these modes of transport. It should be noted that the standard does not cover the following in detail:

  • Dangerous Goods List
  • Classification test criteria
  • Packaging performance requirements
  • Packaging design and construction

The appendix section has been expanded to include additional new informative and normative appendices. Two new appendices which are of note are Appendices J and K. The transport of Lithium batteries is covered in depth in Appendix J – Class 9 Lithium batteries (Informative). The text includes an explanation of types of Lithium batteries, identification of common applications, calculations for watt/hour ratings, identification of which Lithium batteries are considered dangerous goods, transport requirements including how to handle Lithium batteries that are damaged or defective and also how to dispose and recycle those that are not. Appendix K – Asbestos (Normative) provides basic information on Asbestos, other relevant standards, recommendations for waste disposal including containment and its transport.

New Zealand is also releasing a supporting handbook (SNZ HB 5433:2021), containing the complete Dangerous Goods List, which is due to be released early 2021. The importance of this new list is the inclusion of the complete Dangerous Goods List (Chapter 2.3 of the UNRTDG). It also contains supplemental information from the IMDG. This enables the determination of whether the dangerous good is also a Marine Pollutant. This handbook is intended to be updated more frequently than the standard as changes are made to the UN list every two years.

Recommended Action Items:

  • Review key changes of the revised Standard if you transport Dangerous Goods within New Zealand via land to determine impact on your product line.
  • Purchase the latest edition of the New Zealand Standard NZS 5433:2020 from Standards New Zealand.
  • Keep alert for the release of the supporting handbook.
