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 The rule mandates manufacturers and importers of 16 specified chemical substances to submit lists and copies of unpublished health and safety studies to EPA.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.
