What P273 says

Official

Avoid release to the environment.

Category

Prevention · GHS revision 9

Does your label need P273? 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 →

P273 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.

03 · Legal status

Where P273 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 · Substances

Substances carrying P273

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, 260 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.
