H224 in the 24 official EU languages

A label put on the market in an EU country must carry the wording of that country's own language version of CLP — not a translation of the English one. These 24 lines are quoted from the consolidated regulation, Annex III, and are the text to print.

Source: CELEX:02008R1272-20260501, Annex III. © European Union, https://eur-lex.europa.eu — only the electronic Official Journal of the European Union is authentic. Irish is one of the 24 official languages and its H and P texts are printed inside the multilingual Annex tables, but no consolidated CLP has ever been published in Irish — which is why an Irish-primary label cannot be built here.

03 · Legal status

Where H224 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 H224
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	Current

SDS Manager

A hazard statement is not chosen — it follows from the classification, and the same code then has to stand in section 2 of the safety data sheet and on the label, in the official wording of every language the product is sold in. For doing that once and keeping it current when a classification changes, the solution we recommend is SDS Manager (ExactSDS). It also offers SDS management and a broader EHS suite.
