A UN Number is a four-digit identifier assigned by the United Nations Committee of Experts on the Transport of Dangerous Goods to hazardous substances and articles, used to standardize the transportation and handling of dangerous goods internationally.
The UN Number is a critical element in the classification and regulation of hazardous materials, ensuring consistent identification and management across global supply chains. Each UN Number corresponds to a specific hazardous substance or article, providing essential information for safe transport, handling, and emergency response. These numbers are used in conjunction with standardized shipping names, hazard classes, and packing groups to communicate the risks associated with the material. Proper use of UN Numbers helps in complying with international regulations such as the International Maritime Dangerous Goods (IMDG) Code, the International Civil Aviation Organization (ICAO) Technical Instructions, and various national regulations. Accurate identification with UN Numbers ensures the safety of personnel, the public, and the environment during the transportation of dangerous goods.
