Free UN Number Lookup

This is a reference tool — not a compliance verdict.

The entries here are factual data transcribed from the published UN Dangerous Goods List. They tell you what a UN number requires in general; they cannot confirm that your specific shipment — its concentration, packaging, labels and documents — is actually compliant. Many substances have multiple entries by concentration, packing group or physical state.

Always verify against the current regulation edition for your shipment. To check your real package, scan it.
