UN Certified Boxes

UN Certified Cardboard Boxes are specially designed to be certified to UN standards for the transport of dangerous goods by Road, Rail, Air and Sea. UN Certified Boxes can be used to carry any goods permitted on the dangerous goods list supplied by the UN to the appropriate max gross weight.

When buying UN Certified Boxes, the amount of goods you are permitted to carry in any individual box is determined by the maximum gross weight certification for that box (its 4G or 4GV rating). The 4GV rating applies to goods contained in an inner container that is not certified, and the 4G rating applies to goods held within one of our certified containers. Please contact our sales team for a complete list. Please note, for all boxes used within the 4GV specification, a certified inner polythene liner must be used. Please see below for the appropriate product code, available from this website.
