EPA Adds Paperwork for New Chemical Uses
Published Date: 7/29/2025
Rule
Summary
The EPA is setting new rules for certain chemicals, making sure companies tell them 90 days before starting new ways to make or use these chemicals. This helps the EPA check if the new uses are safe before anything begins. If you make or import these chemicals, you’ll need to follow these rules to avoid surprises and delays.

90‑Day Pre‑Notice for New Uses
If you manufacture or import the listed chemical substances, you must notify the EPA at least 90 days before starting any activity that the rule calls a "significant new use." "Manufacture" in this rule includes import. You may not begin the new manufacture or processing until EPA reviews the notice, makes a determination, and takes any actions required by that determination.
Which Substances Are Covered
The rules apply to certain chemical substances that were the subject of premanufacture notices (PMNs) and a Microbial Commercial Activity Notice (MCAN) and that are also subject to an EPA Order under the Toxic Substances Control Act (TSCA). Only persons who manufacture, import, or process those specifically listed substances are covered by the 90‑day notification requirement.
