UN Numbers

UN Numbers are four-digit codes assigned by the United Nations to identify hazardous materials and substances during transport. They help ensure safety, proper handling, and emergency response by providing a standardized way to recognize the type of chemical or material involved. For example, a UN Number can indicate flammable liquids, poisons, or corrosive substances. These numbers are used on labels, shipping documents, and safety protocols worldwide, simplifying international transportation and communication about potentially dangerous items, and promoting safety across different languages and regulatory systems.
