What is a UN ID No?

A UN ID No, or United Nations Identification Number, is a four-digit number that is specifically designated to identify hazardous materials. This system is part of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) and is essential for ensuring the safety of transport, handling, and storage of dangerous goods. These numbers provide critical information about the nature of the substances being transported. They help emergency responders quickly identify risks in the event of an incident, facilitating more effective and safer management of hazardous situations.

The significance of the UN ID No resides in facilitating international transport and communication regarding hazardous materials, as all relevant parties recognize and understand these standardized identifiers. This adds an essential layer of safety in industries that deal with potentially dangerous goods.
