EPA extends comment period for proposed TSCA Section 5 SNURs on certain chemical substances (26-2)

EPA extended the public comment period for the proposed TSCA Section 5 Significant New Use Rules (SNURs) titled “Significant New Use Rules on Certain Chemical Substances (26-2).” The comment deadline is extended to July 10, 2026. This affects stakeholders planning to submit comments on the proposed SNURs and provides additional time to evaluate potential impacts on manufacturing (including import) or processing of substances subject to TSCA orders and SNUR-based notice requirements (SNUNs) prior to designated significant new uses.
