What H371 says
May cause damage to organs <or state all organs affected, if known> <state route of exposure if it is conclusively proven that no other routes of exposure cause the hazard>. The wording is incomplete on purpose. The organ or organs affected, if known, and the route of exposure where it is conclusively proven that no other route causes the hazard.
May cause damage to organs. How it usually reads on a label and on a safety data sheet. We show it separately rather than presenting a filled-in blank as the regulation's own text.

Where H371 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 H371
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, 1 is a group entry 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.
