Hazard Communication Standard; Corrections

ACTION: Final rule; correction and technical amendment.

SUMMARY: OSHA is correcting several inadvertent errors in its Hazard Communication Standard (HCS). Most errors relate to the HCS final rule published in the Federal Register on May 20, 2024. On October 9, 2024, the agency issued a corrections notification and technical amendment to correct errors in that final rule which the agency believed could lead to confusion during the classification process or errors on labels and Safety Data Sheets (SDSs) if not expeditiously corrected. Following publication of the October 9, 2024 corrections notification and technical amendment, OSHA continued its review of the regulatory text and identified additional minor and typographical errors in the regulatory text and appendices to the HCS. OSHA is issuing this correction document to address these additional minor errors. OSHA is also making one technical amendment to an appendix of the HCS unrelated to the May 20, 2024 final rule.

DATES: The corrections in this document are effective January 8, 2026.

Technical Amendments to the EPCRA Hazardous Chemical Inventory Reporting Requirements To Conform to the 2024 OSHA Hazard Communication Standard

ACTION: Direct final rule.

SUMMARY: The Environmental Protection Agency is taking direct final action to conform the Emergency Planning and Community Right-to-Know Act hazardous chemical inventory reporting regulations to the Occupational Safety and Health Administration’s Hazard Communication Standard amendments of 2012 and 2024. The Emergency Planning and Community Right-toKnow Act and its regulations rely on the Occupational Safety and Health Administration’s Hazard Communication Standard for the definition of a hazardous chemical and for the categories of health and physical hazards that must be reported under the hazardous chemical inventory regulations. This action will conform the terminology used and information that must be reported on the hazardous chemical inventory forms to the Hazard Communication Standard amendments. As a result, this action will also improve first responder and community safety, reduce discrepancies and confusion, prevent interpretation burdens on facilities when using (Material) Safety Data Sheets to complete annual hazardous chemical inventory reports, and improve clarity.

DATES: This final rule is effective on January 16, 2026 without further notice, unless the EPA receives adverse comment by December 17, 2025.
