The Mixed Class Label is used as a placard on cargo transport units transporting more than one class or division of dangerous goods, excluding LQ (Limited Quantities) loads.


  • It is not a package label.


  • It is not part of the UN labelling system.


  • It is used as a transport placard for road or rail transport within Australia (and New Zealand) only.

Per the Australian Dangerous Goods Code vehicle placards must correspond to the primary risk of the goods contained in the cargo transport unit or placardable unit except when there are dangerous goods of more than one class or division in a cargo transport unit, in which a placard in the form of a mixed class label may be used in lieu of multiple placards where permitted.

Placards must also be displayed for those subsidiary risks for which a subsidiary risk label is required. However, cargo transport units containing goods of more than one class or division need not bear a subsidiary risk placard if the hazard represented by that placard is already indicated by a primary risk placard or where a mixed class placard is displayed where permitted.

All road vehicles transporting a placard load of dangerous goods must be placarded on the front and rear of the vehicle with placards indicating what dangerous goods are being carried. Where all of the dangerous goods are of a single class or division, the placards required are: (a) the class or division label; and (b) any subsidiary risk labels applicable to the goods.


Where there is more than one class of dangerous goods on the vehicle during the journey, the placards required are either or both of the following: (a) mixed class labels; (b) all class and division labels for each primary and subsidiary risk of the dangerous goods on the vehicle.
