The OSHA HazCom Deadline: What Employers Must Do by November 20, 2026

Short answer: OSHA updated its Hazard Communication Standard in 2024 to align with the 7th revision of the Globally Harmonized System (GHS). For employers, the compliance deadline is November 20, 2026 — by then you must update your workplace labels, your written HazCom program, and your employee training to the new format, with a current safety data sheet on file for every hazardous product. This applies to businesses of every size. SDSentry ($24.99 per location per month) is built to get a small employer ready — SDS library, GHS labels, documented training, and the written program in one place. Here is the full picture.

What changed

OSHA finalized the updated Hazard Communication Standard (29 CFR 1910.1200, often called "HCS 2024") in May 2024, effective July 19, 2024. It aligns U.S. rules with GHS Revision 7 and updates hazard classifications, label elements, and parts of the 16-section safety data sheet format. The changes are being phased in, with different dates for chemical manufacturers and for employers.

The compliance timeline

In January 2026 OSHA extended the original deadlines by four months. The current dates:

Dates per OSHA's HCS rulemaking; the employer substances deadline was extended from the original July 20, 2026. Always confirm the current dates at osha.gov/hazcom/rulemaking.

Does this apply to my business?

Almost certainly yes. The Hazard Communication Standard covers any employer whose employees may be exposed to a hazardous chemical in the course of their work. A small animal shelter using disinfectants, a cleaning company with bleach and degreasers, an auto body shop with solvents and paints, a dental or veterinary practice with sterilants, a pool-service route with chlorine and acid — all are covered, the same as a large manufacturer. There is no small-business exemption from HazCom.

Your November 20, 2026 checklist

1. Update your chemical inventory and SDSs. Make sure you have a current safety data sheet, in the updated format, for every hazardous product on site.
2. Update workplace and secondary-container labels to the new GHS-aligned elements (pictograms, signal word, hazard and precautionary statements).
3. Update your written HazCom program (required by 29 CFR 1910.1200(e)) to reflect the current standard, your chemical list, and your procedures.
4. Retrain employees on the revised label elements and SDS changes, and document who was trained and when.

How SDSentry gets you ready

SDSentry is HazCom and SDS software built for small employers, and it covers exactly these four items in one place: a per-location SDS library with multi-source lookup (and your own uploads), GHS secondary-container labels, per-product training guides with e-signature records, and the written HazCom program — plus OSHA 300 recordkeeping and a no-login Shared SDS Binder so sheets are accessible during every shift. It is a flat $24.99 per location per month with unlimited users and a 14-day free trial, so a small business can be inspection-ready well before the deadline.
