H227 — Combustible liquid
Physical hazard statements describe what the substance itself can do — explode, ignite, react, corrode metal. No substance with a harmonised EU classification carries this code.

Where H227 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.

03 · Substances
Substances carrying H227
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.

Wording quoted from the regulation named above. Substance counts come from harmonised classifications in CLP Annex VI — the statements on a real product also depend on the supplier's own classification. Always check the supplier safety data sheet.
