EPA proposes multiple SNUR batches (24-5.5e; 25-1.5e; 25-2.5e) with comments due Dec 3, 2025

EPA proposed several batches of Significant New Use Rules (SNURs) (24-5.5e, 25-1.5e, 25-2.5e). If finalized, these SNURs would require submission of a SNUN before certain new uses can proceed. Stakeholders had an opportunity to comment (deadline stated as Dec. 3, 2025) and should track finalization outcomes for implications on commercialization, import, and downstream use conditions.
