Background

Section 8(b) of TSCA required EPA to establish a rule on CBI claims for specific chemical identities for chemicals reported as “active” in U.S. commerce in response to the TSCA Inventory Notification (Active-Inactive) Rule.

On February 19, 2020, EPA finalized a rule on the procedures for companies to substantiate their CBI claims for specific chemical identities of substances on the TSCA Inventory. Companies that filed a Notice of Activity Form A and claimed specific chemical identities as CBI have 180 days from the effective date of the final CBI rule, or until November 1, 2020, submit or amend their CBI substantiations.
