What is a UN Number? A Comprehensive Guide to Its Legal Definition
Definition & Meaning
A UN number is a four-digit code assigned to hazardous materials for the purpose of international transport. This number is essential for the safe and efficient movement of these substances by road, water, and air. It helps emergency responders quickly identify the nature of the hazardous material in case of a spill or release. Some substances, like acrylamide, have unique UN numbers (e.g., UN2074), while others may share a common UN number based on similar properties, such as flammable liquids, which are designated as UN1993.
