UN Number
Definition of UN Number
A UN number (United Nations number) is a four-digit code used internationally to identify hazardous substances and articles (such as explosives, flammable liquids, toxic materials, etc.) in the context of transport.
The United Nations Committee of Experts on the Transport of Dangerous Items assigned these numbers, which are used internationally to guarantee the handling and transit of dangerous items in a safe and uniform manner.
Identification
Each UN number corresponds to a specific hazardous substance or a group of substances with similar properties. For example, UN 1203 is assigned to petrol, and UN 1005 is assigned to ammonia.
Classification
Several classifications of hazardous goods are distinguished according to the nature of the hazard (e.g., explosives, gases, flammable liquids, etc.). There are handling and transit guidelines unique to each class.
Regulations
Companies involved in the transport of hazardous materials must comply with regulations that involve using UN numbers and ensuring proper labelling, packaging, and documentation.
Using UN numbers helps in maintaining safety standards and provides a standardised system to manage hazardous materials during transportation.
A UN number must be listed on the Material Safety Data Sheet (MSDS) of your shipment.
