Update 

The U.S. Environmental Protection Agency (EPA) has announced a further extension of the reporting deadline for unpublished health and safety data on 16 chemicals under TSCA Section 8(d). The new deadline for all substances is now May 22, 2026. 

This extension gives EPA additional time to finalize guidance and address industry concerns, particularly around submissions involving confidential business information. The chemicals affected include benzene, bisphenol A, styrene, vinyl chloride, among others under consideration for TSCA risk evaluation. 

These reports will support EPA’s ongoing chemical prioritization and risk management efforts.
