What is this tool?

The GHS Rev 7 Transition Wizard maps HCS 2012 / GHS Rev.3 to HCS 2024 / GHS Rev.7. It tracks the tiered compliance deadlines: May 19, 2026 for manufacturers and November 20, 2026 for employer labeling and training.

OSHA requirement

Per 29 CFR 1910.1200(j) as amended, chemical manufacturers and importers must comply with all modified provisions—including GHS Rev 7 classifications—by May 19, 2026. Employers must update workplace labeling, written HazCom programs, and employee training for newly identified hazards by November 20, 2026.

How to use it

Select your role (Manufacturer, Distributor, or Employer) to see your compliance cutoff dates. Use the wizard to reclassify hazard classes (e.g., Flammable Gas 1A/1B, Desensitized Explosives, Aerosols Cat 3) and update SDS Section 2.

How to Map HCS 2012 Classes to GHS Revision 7

1. Select your role: Choose Manufacturer/Importer, Distributor, or Employer to see your specific compliance deadlines.
2. Answer the questionnaire: Indicate which chemical types you handle (aerosols, desensitized explosives, pyrophoric gases, etc.).
3. Review the transition map: See how each affected hazard class maps from old to new classification with detailed change descriptions.
4. Plan your updates: Use the transition summary to update SDSs, labels, and training materials before the 2026 deadlines.
