TSCA Inventory
From WolfWikis
From the EPA:
EPA classifies chemical substances as either "existing" chemicals or "new" chemicals. The only way to determine if the substance you are working with is a new chemical is by consulting EPA's Toxic Substances Control Act Chemical Substance Inventory (commonly referred to as the TSCA Inventory or just the Inventory). Any substance that is not on the Inventory is classified as a new chemical. If a substance is "new", it can be manufactured for a commercial purpose only if it is subject to an exemption from PMN reporting or a TSCA reporting exclusion (for example, a Low Volume Exemption, or exclusion as a naturally-occurring material). For substances which are "existing", the Inventory can be used to determine if there are restrictions on manufacture or use under the Toxic Substances Control Act (TSCA)Exit Disclaimer.There are approximately 75,000 chemical substances, as defined in Section 3 of the TSCA, on the Inventory at this time.

Ways to tell if a chemical is on the TSCA inventory
- Search the EPA's Substance Registry System. Conduct a search for a chemical, then see if the record contains any TSCA inventory information under Regulatory Resources.
- Go to the search interface on the EPA site at http://iaspub.epa.gov/srs/search$.startup. Scroll down to the Searches Using Lists section and select [TSCA Inv] TSCA Inventory from the list and click Begin Search (you may wish to select the 'sort by CAS number' option as well). You'll then get the full list. (This is a somewhat convoluted approach to viewing the inventory, but it is possible.)
- Find its MSDS. Check the regulatory information to see its TSCA status.
- Check the Libraries' holdings. We have the older printed edition of the inventory and a few associated materials.
