May 22, 2026

The Environmental Protection Agency (EPA) issued a final rule on May 22, 2026, extending the reporting deadline for the Toxic Substances Control Act (TSCA) Section 8(d) Health and Safety Data Reporting Rule from May 22, 2026, to May 21, 2027.

Who’s impacted?

The TSCA Section 8(d) Health and Safety Data Reporting Rule applies to manufacturers (including importers) of any of the 16 chemical substances listed at 40 CFR 716.120(d), including:

Entities that currently manufacture (including import) any of the chemicals; and
Entities that have manufactured (including imported) or have proposed to manufacture (including import) any of the chemicals since January 13, 2015.

What’s required?

The rule requires covered manufacturers (including importers) to submit a one-time report of data on the chemicals from unpublished studies on:

Health and safety;
Environmental effects; and
Occupational, general population, and consumer exposure.

Which chemicals are covered?

The TSCA Section 8(d) Health and Safety Data Reporting Rule applies to:

4,4-Methylene bis(2-chloraniline);
4-tert-octylphenol(4-(1,1,3,3-Tetramethylbutyl)-phenol);
