Dangerous goods packages must be marked and labelled before they are assigned for shipment. The differences between marking and labelling under TDG are listed as below:
The picture below shows how a dangerous goods package should be marked and labelled.
Selected dangerous goods packed in small quantities (limited quantity) or very small volumes (excepted quantity) pose a lesser risk in transport than do the same goods packed in larger volumes. Thus they qualify for some relief from robust packaging requirements provided that they are packed and marked properly. This could save considerable packaging costs.
The picture below shows the marking for limited quantity and excepted quantity dangerous goods.
Environmentally hazardous substances mark (dead fish symbol) shall be put on outer package for class 9 dangerous goods assigned with UN 3077 and UN 3082. See example below for zinc oxide.
It shall be noted that IMDG code and ADR also require the environmentally hazardous substances mark for dangerous goods shipments other than UN 3077 and UN 3082 as long as the dangerous goods are listed as marine pollutants or meet the criteria of marine pollutants (see example below).
