What is the UN number in the Hydrogen Bromide shipping paper example?

Explanation:
UN numbers serve as quick identifiers for hazardous materials in transport, showing up on shipping papers so everyone from drivers to first responders knows exactly what chemical is involved and what safety steps to take. For hydrogen bromide, the UN number is 1048. This code uniquely matches that substance in the UN list, helping you pull the right safety data and handling procedures regardless of packaging or labeling. The UN number itself isn’t a statement about hazard class or packing group—that information appears elsewhere on the paper. Other numbers would point to different chemicals, so they wouldn’t match hydrogen bromide.
