HazCom 2024 SDS Updates — Deadline Compliance for US Chemical Products
OSHA's 2024 final rule aligns the Hazard Communication Standard with GHS Revision 7. Every SDS and workplace label in the United States needs review. Chemply runs the gap analysis, reclassifies the products, and delivers updated, audit-ready documentation before the 2026 and 2027 deadlines.
The HazCom 2024 final rule is the biggest update to OSHA's Hazard Communication Standard since 2012. New aerosol sub-categories, revised flammable gas thresholds, desensitised explosives, and clarified trade-secret disclosure rules mean that most existing SDS will need at least partial reauthoring. Manufacturers and importers have until 19 January 2026 for substances and 19 July 2027 for mixtures. Chemply helps US chemical suppliers, distributors, and downstream employers update their portfolios methodically — before enforcement begins.

Frequently asked questions
What is the HazCom 2024 update?
On 20 May 2024, OSHA published a final rule amending the Hazard Communication Standard (29 CFR 1910.1200) to align with GHS Revision 7, with selected provisions from Revision 8. It introduces new hazard categories, updates classification criteria, and revises label and SDS content requirements.
What is the compliance deadline?
Chemical manufacturers, importers, and distributors evaluating substances must comply by 19 January 2026. Mixtures must comply by 19 July 2027. Downstream employers updating workplace labels, written programs, and training must follow six months after each of those dates.
What actually has to change on my existing SDS?
New aerosol sub-categories (including chemicals under pressure), updated flammable gas categories, desensitised explosives, and revised criteria for skin / eye / respiratory sensitisation. Section 2 hazard statements, precautionary statements, and Section 3 disclosure thresholds for trade-secret concentration ranges all need review.
How does Chemply handle the update?
We perform a gap analysis on your current SDS portfolio against HazCom 2024, reclassify affected products, redraft Sections 2, 3, 9, 11, and 15 as needed, regenerate workplace label artwork, and deliver a versioned PDF with a clear change log for your QA records.
Do I need to update labels at the same time?
Yes. The label on the immediate container must match the classification on the SDS. Where the classification changes, the workplace label (and any shipped-container label) must be reprinted or relabelled before the applicable deadline.
