Response · GHS revision 9

Does your label need P304? That depends on the hazard classes of your product, on whether it goes to the public or to professionals, and on what else is already on the label — Annex IV column 5 lets one statement remove another. Work it out from a classification →

P304 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 IV, and are the text to print.

Source: CELEX:02008R1272-20260501, Annex IV. © 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.

Where P304 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.

04 · On a label

P304 usually appears combined

CLP Annex IV defines combined statements as single label elements. P304 is a component of one of them — this is how you will actually see it printed.

CodeCombined statement
P304+P340 IF INHALED: remove person to fresh air and keep comfortable for breathing. CLP verbatim: IF INHALED: Remove person to fresh air and keep comfortable for breathing.

Substances carrying P304

Every entry whose harmonised CLP Annex VI classification includes this precautionary statement. Substances with a reference page here open on this site; the rest open on ghssymbols.com. Of these, 60 are group entries such as “beryllium compounds” or “salts of hydrazine” — Annex VI gives them no CAS number, so they are listed by Index No and have no page of their own.
