Labels & marking

The correct ADR 5.2 placards and package marks for a UN number — each cited.

ADR 2025
Placards are drawn from the row's labels; marks per ADR 5.2.

How it works

Enter a UN number or substance name to see the primary hazard placard and any subsidiary labels (from the ADR 3.2.1 Table A entry), a package-marking preview, and the ADR 5.2 checklist of conditional marks — orientation arrows, limited-quantity and environmentally-hazardous marks — for the human to confirm. Each is cited.
