UN Packaging Codes
The storage and transportation of hazardous materials (HAZMAT) is overseen and regulated by federal and international law. A comprehensive marking system called the UN marking guide was developed so that HAZMAT packaging can describe what type and how much of a material may be transported within a package. A UN code is a universal system of demarcation developed by the United Nations and used internationally for the classification, packaging, marking, and labeling of dangerous goods to better transport them safely. Rigorous testing is required before a UN certification mark can be given.
