TSCA Inventory of Chemical Substances is a list of existing chemical substances that are manufactured or processed in the United States. Currently, there are more than 84,000 chemical substances on the Inventory.
There are two sections in TSCA inventory: public section and confidential section. Only the public portion is available for search. There are two options to access TSCA inventory:
Amended TSCA requires EPA to designate chemical substances on the TSCA Chemical Substance Inventory as either “active” or “inactive” in U.S. commerce. When you search TSCA inventory, you shall not only check if your substance is listed or not. You shall also check if your substance is "active" or "inactive". Substances designated as "active" on TSCA inventory can be manufactured, imported or processed without notification.
Substances destinated as "inactive" on TSCA inventory must be notified to the US EPA via Notice of Activity Form (NOA-B) 90 days prior to manufacture, import or processing. On receiving the notification form NOA-B, EPA will change the designation of the notified chemical substance on the TSCA Inventory from inactive to active.
If your substance is not listed on TSCA inventory at all, the new substance 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).
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."
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.
