Agency again delays submission deadline for TSCA Section 8(d) health and safety data
The Environmental Protection Agency (EPA) has again delayed the deadline for submitting data on 16 chemical substances required by the Toxic Substances Control Act (TSCA) Health and Safety Data Reporting rule. Manufacturers (including importers) now have until May 22, 2026, to report on all of the covered chemical substances.
What’s required?
The TSCA Section 8(d) Health and Safety Data Reporting rule (40 CFR Part 716) requires manufacturers (including importers) of 16 chemicals to report data from:
- Unpublished health and safety studies; and
- Unpublished studies on environmental effects and occupational, general population, and consumer exposure.
The covered chemicals include:

Note that EPA’s first extension in March 2025 moved the submission deadline for vinyl chloride to June 11, 2025, and for the remaining 15 chemicals to September 9, 2025. This rule pushes the submission deadline for all chemicals (including vinyl chloride) to May 22, 2026.
Who’s covered?
The rule applies to manufacturers in the North American Industrial Classification System (NAICS) codes for chemical manufacturing (NAICS code 325) and petroleum refineries (NAICS code 324110) that:
- Currently manufacture (including import) a covered chemical, or
- Manufactured (including imported) or proposed to manufacture (including import) a covered chemical within the past 10 years.
The reporting requirement also applies to manufacturers of substances for commercial purposes that coincidentally produced a covered chemical during the manufacture, processing, use, or disposal of another substance or mixture (including byproducts and impurities).
How do you report?
Reporters submit the TSCA Section 8(d) data via the Chemical Information Submission System (or CISS) tool on the Chemical Safety and Pesticide Program (CSPP) system. The CSPP is accessed through EPA’s Central Data Exchange.
Key to remember: Manufacturers now have even more time to submit TSCA Section 8(d) health and safety data reports for 16 chemical substances.
