H332 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 H332 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.

EU CLP Regulation (EC) 1272/2008 CLP Annex IV, Part 2 (consolidated) Current

04 · On a label

H332 also appears combined

CLP Annex III defines combined hazard statements as single label elements. H332 is a component of 3 of them — this is how you will actually see it printed. The combinations have no pages of their own: a plus sign in a URL has to be encoded and breaks in other people's links and in analytics.

CodeCombined statement
H302+H332 Harmful if swallowed or if inhaled. CLP verbatim: Harmful if swallowed or if inhaled
H312+H332 Harmful in contact with skin or if inhaled. CLP verbatim: Harmful in contact with skin or if inhaled
H302+H312+H332 Harmful if swallowed, in contact with skin or if inhaled. CLP verbatim: Harmful if swallowed, in contact with skin or if inhaled

05 · Substances

Substances carrying H332

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, 21 are group entries 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.
