EPA Proposes to Extend TSCA Health and Safety Reporting Rule Deadline to 2027

What: On March 30, 2026, the U.S. Environmental Protection Agency (EPA) proposed to extend the Toxic Substances Control Act’s (TSCA) Health and Safety Data Reporting rule deadline to May 21, 2027.

Why: The Health and Safety Data Reporting rule was finalized on December 13, 2024. EPA is currently considering revisions to the rule. Rather than requiring businesses to prepare submissions under a rule that is in the process of being revised, the proposed extension would provide regulatory certainty and prevent duplicative or potentially inconsistent reporting.

The rule requires manufacturers (including importers) of 16 chemical substances to submit copies and lists of certain unpublished health and safety studies to the EPA. Specifically, the rule requires information on when a company is importing the chemical as a pure substance, or within a mixture, formulated product, or article that contains the subject chemical. The chemicals covered by the rule are:

  • 4,4-Methylene bis(2-chloraniline) (MBOCA).
  • 4-tert-octylphenol(4-(1,1,3,3-Tetramethylbutyl)-phenol).
  • Acetaldehyde.
  • Acrylonitrile.  
  • Benzenamine.  
  • Benzene.  
  • Bisphenol A.  
  • Ethylbenzene.  
  • Naphthalene.  
  • Vinyl Chloride.  
  • Styrene.  
  • Tribromomethane (Bromoform).  
  • Triglycidyl isocyanurate.  
  • Hydrogen fluoride. 
  • N-(1,3-Dimethylbutyl)-N’-phenyl-p-phenylenediamine (6PPD) (CASRN 793-24-8).                 
  • 2-anilino-5-[(4-methylpentan-2-yl) amino] cyclohexa-2,5-diene-1,4-dione (6PPD-quinone) (CASRN 2754428-18-5). 

When an updated rule is finalized, the EPA will communicate updated reporting requirements and timelines to the regulated community. The EPA is not reopening or reconsidering provisions of the underlying regulations other than the submission deadline in the rule.

Action: Read the proposed rule and submit comments before the April 27, 2026, deadline.

PROPOSED RULE:

Reporting Deadline Extension for the Health and Safety Data Reporting Rule Under Toxic Substance Control Act (TSCA) Section 8(d)

ORIGINAL HEALTH & SAFETY DATA REPORTING RULE:

Certain Existing Chemicals; Request to Submit Unpublished Health and Safety Data Under the Toxic Substances Control Act (TSCA)
