CLASS 9 – MISCELLANEOUS DANGEROUS SUBSTANCES AND ARTICLES,
INCLUDING ENVIRONMENTALLY HAZARDOUS SUBSTANCES

 

Miscellaneous dangerous goods are substances and articles which during transport present a danger or hazard not covered by other classes. Miscellaneous dangerous goods present a wide array of potential hazards to human health and safety, infrastructure, and the environment. Class 9 substances and articles may be in UN Packing Group II or III, or have no Packing Group. Class 9 articles and substances are subdivided as follows:

  • Substances which, on inhalation as fine dust, may endanger health, i.e asbestos.

  • Substances evolving flammable vapour, i.e polymeric beads, plastics moulding compound.

  • Lithium batteries, i.e lithium metal batteries, lithium alloy batteries, lithium ion batteries, also contained in or packed with equipment. In the 2017 edition of the ADG Code it was made a requirement that transportation of lithium batteries must exclusively use the new Class 9a label (figure 2 below), from 31 December 2018. Lithium batteries are the only Class 9 item assigned to UN Packing Group II. Due to the hazards associated with lithium batteries, lithium batteries and articles and are now assigned their own UN numbers:

    UN 3090 — lithium metal batteries (including lithium alloy batteries)
    UN 3091 — lithium metal batteries contained in equipment, lithium metal batteries packed with equipment, or lithium metal batteries packed with equipment
    UN 3480 — lithium ion batteries (including lithium ion polymer batteries)
    UN 3481 — lithium ion batteries contained in equipment, lithium ion batteries packed with equipment, or lithium ion polymer batteries packed with equipment
    UN 3536 — lithium batteries installed in cargo transport unit, lithium ion batteries, or lithium metal batteries.

  • Capacitors, i.e. electric double-layer capacitors, asymmetric capacitors.

  • Life-saving equipment, i.e self inflating and non self inflating life saving appliances, electrically initiated safety devices.

  • Substances and articles which, in the event of fire, may form dioxins, i.e polychlorinated liquids and solids, polyhalogenated liquids and solids.

  • Substances transported or offered for transport at elevated temperatures, i.e liquids above 100°c, eg. molten metal, and solids above 240°c. These are in UN Packing Group III.  

  • Environmentally hazardous substances, i.e substances and mixtures which are dangerous to the aquatic environment that do not meet the classification criteria of any other class or another substance within Class 9. These include GMOs and GMMOs not otherwise classified in Division 6.2. Per the ADG Code, a cargo transport unit containing environmentally hazardous substances meeting the criteria of UN 3077 "Environmentally Hazardous Substance, Solid, N.O.S" and UN 3082 "Environmentally Hazardous Substance, Liquid, N.O.S" must also be marked with the environmentally hazardous substance mark (figure 3 below.) The mark must be placed on each surface of the unit that is required by the Code to be placarded, as near as is practicable to the required class or division label. Environmentally hazardous substances meeting the descriptions of UN 3077 or UN 3082 are not subject to the Code when transported by road or rail in packagings that do not incorporate a receptacle exceeding 500 kg / litres, or IBCs.
