The UN number, also known as the United Nations Number, is a critical identifier used on industrial packaging, including fiber drums, to specify the type of hazardous materials or substances that a container is certified to transport. This alphanumeric code is universally recognized and plays a vital role in ensuring the safe handling and transportation of dangerous goods globally.

What Does the UN Number Represent?

The UN number consists of a series of codes that convey essential information about the packaging and its contents. Here's a breakdown of what each part of the UN number signifies:

1. Packaging Group: Indicated by a Roman numeral (I, II, or III), this code represents the level of danger associated with the material being transported. Packaging Group I indicates high-risk materials, while Group III denotes lower-risk substances .

2. Material Type: The first digit of the UN number specifies the type of packaging used. For example, "1" represents drums or barrels, which are commonly used for transporting liquids or solids .

3. Material Composition: The second digit indicates the material from which the drum is constructed. For instance, "3" could refer to steel drums .

4. Opening Type: The third digit describes whether the drum has an open or closed head design .

5. Performance Level: The final segment of the code includes letters such as "X," "Y," or "Z," which denote the performance level of the packaging tested under specific conditions like drop tests, hydraulic tests, and stack tests .

Why Is the UN Number Important?

The UN number serves several purposes:

• It helps shippers, carriers, and regulatory authorities identify the type of material inside the drum and its associated risks.
• It ensures compliance with international safety standards for transporting hazardous materials.
• It provides critical information to emergency responders in case of an accident .
