Confidential Business Information under TSCA

Statistics for the TSCA CBI Review Program

Under the Toxic Substances Control Act (TSCA), EPA must review and make determinations for certain confidential business information (CBI) claims. Specifically, TSCA section 14(g)(1) requires that EPA, within 90 days of receipt of the claim:

  • review and make determinations on confidential business information (CBI) claims for chemical identity after the chemical substance has been offered for commercial distribution; and
  • review and make determinations on a representative subset of at least 25% of other CBI claims that are not exempt from substantiation and review.

The CBI review requirements of TSCA section 14 apply to submissions to EPA under TSCA, including sections 4, 5, 6, 8, and 12.

TSCA CBI Review Statistics

Since the enactment of the TSCA amendments in June 2016, EPA has established numerous new processes, systems, and procedures to enable submitters to provide the information required when making confidentiality claims and to facilitate EPA's review, and where applicable, determinations on these claims. The statistics provided below show EPA's progress toward meeting the requirements of TSCA section 14. A “case” is a submission made under a specific section of TSCA and all subsequent submissions and amendments by the same submitter that relate back to the first submission.

CBI Review Statistics (cases received between June 22, 2016 and June 15, 2020)
Cases in which the specific chemical identity is subject to CBI review 3,326
Cases in which information other than the specific chemical identity is subject to CBI review 2,523
Cases in which both the specific chemical identity and information other than the specific chemical identity is subject to CBI review 734
Total cases subject to CBI review 6,583
Cases resulting in final CBI determinations
Cases with all CBI claims subject to review, approved 882
Cases with all CBI claims subject to review, denied 602
Cases with CBI claims subject to review, approved-in-part/denied-in-part 97
Total cases resulting in final CBI determinations 1,581
Cases reviewed with no final CBI determination necessary
Cases with all CBI claims screened and found to be exempt from review 1,078
Cases with all CBI claims withdrawn by submitter 430
Cases identified for CBI review, for which no determination required (e.g., in some instances, older EPA information systems do not specifically identify which information is claimed as CBI and upon review, it is determined that no claims require review) 1,500
Total cases reviewed/screened with no final CBI determination necessary 3,008
Cases currently undergoing CBI review
