All dangerous goods transported by domestic and international road and rail must be carried in packages marked with a “UN” symbol. The UN mark indicates that the packaging and its design have been tested and certified in accordance with the specifications set by the United Nations Committee of Experts on the Transport of Dangerous Goods.

All packaging classified as UN certified must first undergo a series of strict testing procedures. These procedures are established to ensure that the packaging meets the minimum acceptable design standards, allowing it to withstand the conditions encountered during the transportation of dangerous goods.
