Reviewing New Chemicals under the Toxic Substances Control Act (TSCA)

New Chemical Notices Received by EPA

The Toxic Substances Control Act (TSCA) requires EPA to publish a list of new chemical submissions received by the Agency under TSCA Section 5. The list of submissions received includes premanufacture notices (PMNs), Significant New Use Notices (SNUNs), Microbial Commercial Activity Notices (MCANs), Test Market Exemption Applications (TMEAs), Notices of Commencement of Manufacture or Import (NOCs), and test information submitted under section 5.

EPA is making this list of new chemical submissions received available in one place on our website to increase transparency and make information on new chemicals easier to find. This provides an alternative to searching individual Federal Register notices and dockets on The links below provide a listing of the following types of new chemical submissions received. These lists will be updated on a regular basis.

You can track the status of active new chemicals cases by visiting our page on statistics for the new chemicals review program.
