TSCA Updates: Reporting Deadline Moved for 16 Chemicals

Posted on 6/13/2025 by Lion Technology Inc.

With a Final Rule on June 9, EPA moved the deadline for chemical manufacturers to submit certain unpublished safety and health studies concerning 16 chemicals specified in a December 2024 rule. The list includes acetaldehyde, benzene, hydrogen fluoride, styrene, vinyl chloride, and other substances—all of which are designated by EPA as high priority substances for risk evaluations mandated by TSCA, as amended.  

For all 16 chemicals listed in the 2024 rule, the deadline to report is now May 22, 2026. EPA extended the submission deadline, in part, to allow more time for development of guidance to assist the regulated community with data submissions.

The chemicals covered by this reporting requirement are:

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

More information about this reporting requirement under TSCA §8(d) can be found on EPA's website.

Draft Risk Evaluations for 2 Phthalates

On June 5, EPA announced that Draft Risk Evaluations are available for two phthalates—dibutyl phthalate (DBP) and diethylhexyl phthalate (DEHP). The agency’s preliminary finding is that both substances pose “unreasonable risk” to human health and the environment. Read the announcement in the Federal Register here. 

EPA will accept public comments on the draft risk evaluations until August 5, 2025. Under the Toxic Substances Control Act (TSCA), as amended, a finding of unreasonable risk must be followed by regulation to address the risk by restricting activity involving the chemical (manufacturing, distribution, etc.) or enacting workplace protections.

Note: The TSCA Activity Tracker has been updated.  

Master TSCA Compliance

The Toxic Substances Control Act (TSCA) is complex and enforcement is stringent, making a comprehensive understanding of the rules critical for compliance.  The law has broad applicability, subjecting all companies that “manufacture, use, process, distribute, import, or export chemical products” to complex reporting and management requirements.
