What Are the Key Changes to the Hazard Communication Standard (HCS) In 2026

The 2024 changes to the HCS improve the information on the labels and safety data sheets for hazardous chemicals. The final rule will also improve alignment with other federal agencies and Canada.
The changes include:
• Revised criteria for the classification of specific health and physical hazards
• Revised requirements for some labels
• Minor changes to the content of Safety Data Sheets (SDSs) and
• New requirements relating to the chemical concentrations that can be claimed as trade secrets.

What Do I Have to Do as an Employer or Worker to Meet the New HazCom Requirements?

Safety data sheets and labels for certain chemicals may undergo slight changes. Companies that use hazardous chemicals should ensure they obtain their suppliers’ most recent safety data sheets.

If your company produces chemicals or formulates chemical mixtures for sale, you must review the amendments to the Hazard Communication Standard and make the necessary changes to classification, labels, and safety data sheets. See the hazard communication standard update infographic below for more information.

For substances classified as pure chemicals with a fixed composition, such as ethanol and hydrogen peroxide, the following updates are necessary:

• Manufacturers, importers, and distributors are required to update labels and Safety Data Sheets by May 19, 2026.
• Employers have additional time and must update workplace labels, written hazard communication programs, and employee training for these substances by November 20, 2026.

The Hazard Communication Standard also has new deadlines for mixtures.
A mixture is defined as a combination or solution made up of two or more substances that do not chemically react with each other. Examples include cleaning solutions and paint. If the substances react, they will form a new substance rather than remain a mixture.

If your company manufactures, imports, or distributes mixtures, it is essential to update labels and Safety Data Sheets by November 19, 2027.
For companies that utilize mixtures, employers must update workplace labels, written hazard communication programs, and employee training by May 19, 2028.
