EPA Demands Chemical Makers' Heads-Up on New Uses
Published Date: 6/23/2025
Rule
Summary
The EPA is setting new rules for certain chemicals, making sure anyone who wants to make or use them in new ways tells the EPA 90 days ahead. This gives the EPA time to check if the new use is safe before it starts. If you work with these chemicals, get ready to follow these rules to avoid surprises and keep things safe!
Analyzed Economic Effects
3 provisions identified: 0 benefits, 3 costs, 0 mixed.
90‑Day Pre‑Notice Before New Chemical Uses
If you plan to make, import, or process any of these listed chemicals for a new use, you must notify the EPA at least 90 days before you start. The 90‑day notice begins EPA's review of that planned use and starts the clock on whether you can proceed.
Cannot Start New Uses Until EPA Decides
You may not begin the manufacture (including import) or processing for the significant new use until EPA has reviewed your notice, made a determination, and taken any actions required by that determination. That review can delay or prevent your planned activity from starting.
Rule Applies to PMN‑Subject Chemicals With TSCA Orders
These significant new use rules apply to chemical substances that were the subject of premanufacture notices (PMNs) and are subject to an EPA Order under the Toxic Substances Control Act (TSCA). If you work with chemicals covered by a PMN and TSCA Order, these SNUR requirements apply.
