Sources and revision notes
The official documents behind every statement in the GHS H and P statement lookup, with the GHS revision each jurisdiction is aligned to.
UN GHS Rev.11
UN GHS, Eleventh revised edition (Rev.11, 2025), Annex 3, sections 1, 2 and 3 (section 3 matrix used for the links between H and P statements)
Aligned GHS revision: GHS Rev.11
Changes are compared with ST/SG/AC.10/30/Rev.10 (2023) incl. Corr.1
US OSHA HCS
US OSHA Hazard Communication Standard, 29 CFR 1910.1200 Appendix C (as amended by 89 FR 44144, May 20, 2024, and 91 FR 562, 574 (Jan. 8, 2026))

Mexico
NOM-018-STPS-2015, DOF 9 October 2015, Apéndice C (Tablas C.1, C.2) and Apéndice D (Tabla D.1), Spanish
Aligned GHS revision: GHS 5th revised edition (2013), "parcialmente equivalente" per section 16 of the NOM
How the comparison works
- “Same as UN” means the English wording matches UN GHS Rev.11 after ignoring case, punctuation and British or American spelling. For OSHA, the placeholder notation (OSHA’s “<…>” and the UN’s spelled-out instructions) is also ignored.
- “Differs” means the English wording is not the same as UN GHS Rev.11. French and Spanish text is shown as published and is not compared word for word.
- “Not adopted” means the jurisdiction does not list the statement, or does not adopt the hazard class or category it belongs to.
- “Combining allowed” (OSHA) means OSHA does not list the combined wording but adopts each part and allows hazard statements to be combined (29 CFR 1910.1200 App. C, C.2.2.1). “In combined statements” means OSHA uses the code only inside combined precautionary statements (C.2.4.6).
- Linked P statements come from the UN GHS Rev.11 Annex 3, section 3 label matrix only. EU CLP, US OSHA, Canada (GHS Rev.7) and Mexico assign their own P statements.
- Codes deleted in the UN GHS keep their pages because other jurisdictions still use them. Each page says which UN revision deleted it.
