Key Facts
- OSHA revised inspection procedures to align with the updated hazard communication standard, 29 CFR 1910.1200.
- A May 19 memo references Paragraph (i), Appendices A, B and C, and Safety Data Sheet Sections 1-3, 8-11 and 14 in Appendix D.
- The memo also addresses coordination with the Department of Transportation on bulk shipment labeling and the EPA definition of “released for shipment.”
- Some of the new rules took effect May 19 for chemical manufacturers, importers and distributors evaluating substances.
- The compliance date for evaluating mixtures is Nov. 19, 2027.
What Happened
OSHA has revised its inspection procedures to align with the agency’s updated hazard communication standard, 29 CFR 1910.1200, which was issued in 2024. The change was outlined in a May 19 memo.
The memo points inspectors to Paragraph (i) on trade secrets, Appendix A on health hazard criteria, Appendix B on physical hazard criteria, and Appendix C on allocation of label elements. It also references revisions to Safety Data Sheet Sections 1-3, 8-11 and 14 in Appendix D.
Why It Matters
For chemical buyers, lab managers, EHS leads and plant operators, the practical issue is inspection readiness. OSHA’s updated procedures indicate what the agency will be looking for when it reviews hazard classification, labels and SDS content under the revised standard.
The report said OSHA is also trying to clarify issues that arose during implementation of the 2012 HCS update and improve alignment with other federal requirements, including DOT and EPA references. That makes cross-functional review of shipping papers, container labels and SDSs more important.
Key Details
The HazCom standard remains aligned to the seventh revision of the United Nations’ Globally Harmonized System of Classification and Labeling of Chemicals, or GHS. The source noted that GHS is now on its 11th revision, published Dec. 9.
- Paragraph (d): hazard classification
- Paragraph (f)(11): label updates
- Paragraph (f)(12): small and very small container labeling
According to the report, part of the new rules went into effect May 19 for chemical manufacturers, importers and distributors who are evaluating substances. The compliance date for evaluating mixtures is Nov. 19, 2027.
What To Watch Next
Companies should watch for how OSHA applies the revised inspection procedures in practice, especially where SDS sections, label elements and mixture evaluation timing intersect with day-to-day compliance work.
It will also be important to track how the agency’s alignment efforts with DOT and EPA shape future enforcement expectations for shipment labeling and release definitions.
Alliance's Take
Customers should review SDS authoring, label generation and hazard classification workflows now, especially for substances already in scope and mixtures with a later compliance date.
Procurement and EHS teams should also check that vendor documentation and internal shipping practices match the updated OSHA references and related DOT/EPA alignment points.
