Confidential Business Information under TSCA

Requesting Access to CBI under TSCA

Amendments to the Toxic Substances Control Act (TSCA) expanded the categories of people who may now access information claimed as confidential business information (CBI) under TSCA. Information that a business claims as CBI under TSCA is protected from disclosure until the business withdraws the CBI claim, until the CBI claim expires, until EPA determines that the claim is not entitled to confidential treatment, or as authorized under TSCA and EPA regulations.

TSCA allows EPA, under certain conditions, to disclose CBI to:

  • state, tribal, and local governments; 
  • environmental, health, and medical professionals; and
  • emergency responders.

Read EPA's guidance documents outlining the circumstances under which TSCA allows the Agency to disclose CBI and how representatives of the three groups listed above can request disclosure.

Read the Federal Register notice announcing the availability of these guidance documents.

You may be able to request access to the following types of information that are often claimed as CBI under TSCA:

  • Specific chemical identity (e.g., the specific name of the chemical)
  • Company name
  • Production figures
  • Manufacturing or processing details
  • Specific uses
  • Names of individual company or laboratory personnel
