Updated TSCA Inventory Now Available

Posted on June 02, 2020 by Roger Marks

Chemical industry stakeholders can now access the updated non-confidential portions of the TSCA inventory.

The TSCA inventory lists all chemicals manufactured, processed, or imported in the United States. Some substances do not appear on the inventory because they are excluded or exempted from regulation under TSCA.

EPA updates the TSCA inventory about once every six months.

Active/inactive Designations

Recent iterations of the TSCA inventory include an active or inactive designation for each chemical. Active chemicals are those that are currently manufactured or imported to the United States. Inactive chemicals are those that are no longer active in commerce.

These active/inactive designations started after EPA required the chemical industry to submit retroactive “reset” reports in early 2018. The “TSCA Reset Rule” report covered every chemical manufactured or imported between June 21, 2006 and June 21, 2016.  

In February 2019, EPA announced that of the 85,000 total chemicals on the inventory, 40,665 were active in commerce (47%).

The updated inventory for June 2020 contains 86,405 chemicals, of which 41,587 are active (48%).  

These active/inactive designations help guide EPA’s efforts to assess the risks of each chemical listed on the inventory, a task required by recent TSCA reforms in the Frank R. Lautenberg Chemical Safety for the 21st Century Act or LCSA. They also serve to inform the chemical industry about whether manufacturing or importing a chemical will require notification to EPA to “re-activate” the substance on the inventory.

TSCA CDR Reporting Opens June 1

The submission window for 2020 TSCA Chemical Data Reporting (CDR) reports—required once every four years—will run from June 1, 2020 to November 30, 2020. This year’s CDR report will cover all activity from 2016, 2017, 2018, and 2019.
