Tips on Searching TSCA Inventory

A substance that is not listed on TSCA inventory will be subject to TSCA section 5 Pre-manufacture Notice (PMN) requirements.

In addition to that, you shall check if your substance is subject to Significant New Use Rules (SNURs) requirements under TSCA. Substances that are subject to SNUR requirements are designated as such by an "S" flag in the Inventory listing. If your chemical substance is subject to a SNUR and your intended manufacture, processing, or use of the substance is a significant new use, you would be required to submit a Significant New Use Notice (SNUN) 90 days prior to the manufacture of that substance. You can also search substances subject to SNURs by using EPA's Substance Registration Services (SRS).

How can I check the confidential portion of TSCA Inventory?

If you cannot find one substance in non-confidential TSCA Inventory data, you may obtain a written determination EPA from by submitting a Bona Fide Intent to Manufacture or Import Notice. However, you need to demonstrate a "genuine intent to manufacture or import."

Are you importing chemical substances to the United States?

TSCA section 13 requires that importers certify their imported chemical substances or mixtures are either: (1) in compliance with TSCA Sections 5, 6 and 7 at the time of import; or (2) not subject to TSCA. Customs can refuse entry of any shipment that does not have a TSCA certification. This certificate could be a self-declaration.
