Disposal · precautionary statement
P503 — Refer to the manufacturer or supplier for information on disposal, recovery or recycling.
Disposal statements cover the leftover product and the empty container. No substance with a harmonised EU classification carries this code.
01 · Wording
What P503 says
Refer to manufacturer/supplier/… for information on disposal/recovery/recycling. The wording is incomplete on purpose. Whom to ask — the manufacturer, the supplier, or another contact they name.
Refer to the manufacturer or supplier for information on disposal, recovery or recycling. How it usually reads on a label. We show it separately rather than presenting a filled-in blank as the regulation's own text.
Disposal · GHS revision 9
Reading the official wording. … is a blank the supplier fills in — not a truncated sentence.· [square brackets] mark a part printed only when it applies. · A slash offers a choice, as in POISON CENTER/doctor.
Does your label need P503? 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 →
02 · Languages
P503 in the 24 official EU languages
We do not yet hold the official translations of P503
This code is current under EU CLP, so the wording does exist in all 24 language versions of Annex IV — we simply have not imported it correctly yet. This is a gap on our side, not in the regulation. Until it is filled, take the wording from the language version of the regulation itself rather than translating the English sentence above: the official text is a legal wording, not a translation choice.
03 · Legal status
Where P503 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.

Substances carrying P503
No substance with a harmonised classification in CLP Annex VI carries this code. That does not mean it is unused — suppliers apply it to their own mixtures.
