Transporting chemicals

Most chemicals are classified as Dangerous Goods and their transport is regulated by the Land Transport Rule: Dangerous Goods 2005 Rule 45001/1. Failure to observe these regulations will result in prosecution.

Please be aware that transport of dangerous goods above threshold amounts will require:

  • dangerous goods declarations and associated documentation
  • the driver of the vehicle to have a dangerous goods endorsement
  • the vehicle must display dangerous goods placarding
  • use of approved packaging and marking
  • adequate segregation of chemicals.

Please note

  • The transport of chemicals (i.e. Transport of Dangerous Goods) is quite complex and the requirements below must be adhered to at all times. Unless single chemicals are being transported, the transport of chemicals must be entrusted to commercial carriers with a Dangerous Goods license endorsement.
  • Chemicals must never be carried on public transport.

Threshold Quantities

The threshold quantities for each UN Class are given below. Transport of quantities above these thresholds will entail the requirements listed above. These threshold quantities only apply to transport as 'tools of trade', domestic or recreational purposes. These thresholds do not apply to commercial carriers. Remember that these apply to single chemicals only.

UN Class Class Name Threshold (kgs/litres)
2.1 Flammable gases 250 litres water capacity
2.2 Non-flammable gases: cryogenic liquids 25 litres water capacity
Non-flammable gases 250 litres water capacity
2.3 Toxic gases (except those listed below) 50 litres water capacity
Cyanogen
Cyanogen chloride
Nitrogen dioxide
Phosgene
 
1 litre water capacity
3, Packing Gp I Flammable liquids 5 litres
3, Packing Gp II Flammable liquids 250 litres
3, Packing Gp III Flammable liquids 250 litres
4.1 Flammable solids 5 kg
4.2 Spontaneously combustible solids None
4.3 Dangerous when wet None
5 .1 Oxidisers 5 kg or 5 litres (liquids)
5.2 Organic Peroxides 5 kg or 5 litres (liquids)
6.1 Toxic 5 kg or 5 litres (liquids)
8 Corrosive 5 kg or 5 litres (liquids)

Please note: the limits for UN Classes 4.1, 5.1, 6.1 and 8 may be higher depending on the Packing Group that the chemical has been assigned.

General rules for packaging chemicals for transport by a carrier


  • Each UN Class of chemical must be packaged separately.
  • Each package must be prominently labelled "Dangerous Goods - UN Class X" (and refer to the title of the UN Class).
  • UN Class 4.1, 4.3, 5.1 and 5.2 chemicals must be transported separately from any other UN class of compound. The carrier must carry them on another vehicle or make another trip.

Transport of individual chemicals as 'tools of trade'


The following only applies to transport of one or two chemicals.

  • Unless single chemicals are being transported, the transport of chemicals must be entrusted to commercial carriers with a Dangerous Goods license endorsement.
  • Persons who are transporting a chemical are required to have documented training in the hazards of the compound. Attendance at the HSNO Lab Managers course is required as a prerequisite.
  • Each UN Class of chemical must be packaged separately.
  • Each package should be prominently labelled "Dangerous Goods - UN Class X" - (and refer to the title of the UN Class), the UN Packing Group and the UN Number of the compound. The label must be clear, legible and properly fixed to the container. The UN Number and Packaging Group can be obtained from ChemWebGold.
  • Packages must be secured inside vehicle.
  • There must be a record of the packages and contents which should be readily available to emergency services in the event of an accident. This record must be kept in a prominent place inside the vehicle.
  • There must be brief instructions about measures to be taken in the event of an emergency. A copy of 'Mini-MSDS' will suffice. This document must also be kept in a prominent place inside the vehicle. You can download and print a copy of this document printed from ChemWebGold.
