UN numbers and dangerous-goods marks
Treat hazard labels as regulated markings, not decorative stickers.
UN numbers identify particular dangerous goods in transport rules. The correct marking depends on the substance, its classification, packaging, quantity, and applicable mode of transport. A label preview can help with layout planning, but a wrong or incomplete mark may create serious delays and safety risks.
Confirm classification and required wording with current official rules and the carrier before shipping. Use approved label stock and exact specifications where required. Do not use a generic template as a certification or assume a similar-looking diamond is compliant.
