TSCA: The U.S. Alternative to REACH Regulation

In response to stakeholder requests, the U.S. Environmental Protection Agency (EPA) has announced an extension of the reporting deadlines under the Toxic Substances Control Act (TSCA) Health and Safety Data Reporting Rule. The rule mandates manufacturers and importers of 16 specified chemical substances to submit lists and copies of unpublished health and safety studies to EPA. 

Extended Reporting Deadline 

The original reporting deadline for all 16 chemical substances was March 13, 2025. However, EPA has now extended the deadlines as follows: 

• Vinyl chloride – New deadline: June 11, 2025 

• Remaining 15 chemical substances – New deadline: September 9, 2025 

These extensions are intended to provide manufacturers and importers with additional time to gather and submit the required data to ensure compliance with the rule.

The U.S. Environmental Protection Agency has extended the public comment periods for two key chemical evaluations under the Toxic Substances Control Act (TSCA), allowing stakeholders additional time to provide feedback on regulatory decisions for C.I. Pigment Violet 29 (PV29) and vinyl chloride. 

Extended Comment Period for C.I. Pigment Violet 29    

On January 14, 2025, EPA released a proposed risk management rule for C.I. Pigment Violet 29 (PV29), a chemical commonly used in paints, coatings, and plastics. The public comment period was originally scheduled to close on February 28, 2025. However, the agency has now extended the deadline by 60 days, to April 29, 2025. 

The extension is intended to give stakeholders, including industry representatives, environmental groups, and the public, more time to review the proposed regulations and submit their comments. Those interested can provide input through the official docket (EPA-HQ-OPPT-2021-0277) at www.regulations.gov. 

Vinyl Chloride Risk Evaluation Comment Period Extension   

Similarly, EPA has extended the comment period for the draft scope document for the risk evaluation of vinyl chloride, a chemical used primarily in the production of PVC plastics. The draft scope document was initially released with the original comment period set to close on March 3, 2025. The extension grants stakeholders an additional 30 days, extending the deadline to April 2, 2025. 

EPA encourages interested parties to submit feedback on the draft risk evaluation through the docket (EPA-HQ-OPPT-2018-0448) at www.regulations.gov.
