H201 — Explosive; mass explosion hazard
Physical hazard statements describe what the substance itself can do — explode, ignite, react, corrode metal. 23 substances with a harmonised EU classification carry this code.

Deleted from UN GHS in Rev.9 (2021) — still current in CLP.
UN GHS Rev.9 marked this code [Deleted]. EU CLP has not followed: the code is legally current on an EU label today. This is the single most common reason a code looks wrong in one reference and right in another.
The UN replacement is H209, a code that is not part of EU CLP.
Nine editions of the UN model text, 86 hazard statements, 19 of which ever moved. Read the full story in what changed in UN GHS Rev.11.

Where H201 is current
GHS is a United Nations model text, revised every two years, and each jurisdiction adopts a revision on its own timetable. A code can be legally current in one system and deleted in another — that is normal, not an error.
| Jurisdiction | Basis | Status of H201 |
|---|---|---|
| EU CLP | Regulation (EC) 1272/2008 CLP Annex IV, Part 2 (consolidated) | Current |
| US OSHA HazCom | 29 CFR 1910.1200 Appendix C UN GHS Rev.7 (final rule of 20 May 2024) | Current |
| US HazCom 2012 | legacy · GHS Rev.3 UN GHS Rev.3, Annex 3 | Current |
| UN GHS | Rev.11 (2025) UN GHS Rev.11, Annex 3 | withdrawn Current equivalent: H209. |

Substances carrying H201
Every entry whose harmonised CLP Annex VI classification includes this hazard statement. Substances with a reference page here open on this site; the rest open on ghssymbols.com. Of these, 1 is a group entry such as “salts of picric acid” or “beryllium compounds” — Annex VI gives them no CAS number, so they are listed by Index No and have no page of their own.
