UN Packaging ExplainerPosted on Jun 14, 2018
In order to ensure safe transport of Dangerous Goods the United Nations have established a universal system for the classification, packaging, marking and labelling of Dangerous Goods. National and international regulations relating to road, rail, sea and air transport are all based on the UN classification system.
Under UN regulations, all packaging used for Dangerous Goods must meet or exceed minimum standards, before it can be used legally for the carriage of dangerous goods. UN packaging certification is issued by approved test centres, which establish packaging suitability and performance by conducting tests as described in Chapter 6.1 of the UN Model Regulations.
If containers pass the tests, all design-types manufactured to the same specification may be marked accordingly with the relevant UN code. Containers can be certified as free standing or in combination with outer packaging such as a cardboard box.
A UN code consists of several components, which each have particular meaning:
Example: UN 3H1/Y1.6/150/18/GB/6840
The mark is for:
3H1: A jerry can (3) – made from plastic material (H) – with a non-removable head (1).
