29 C.F.R. § 1401.26 – Confidential commercial information (“CCI”).

(a) Definitions. For purposes of this section:
Confidential commercial information means information obtained by the FMCS from a submitter that may be protected from disclosure under Exemption 4 of the FOIA, 5 U.S.C. 552(b)(4).
Submitter means any person or entity, including a corporation, State, or foreign government, but not including another Federal Government entity, that provides confidential commercial information, either directly or indirectly to the Federal Government.
(b) Designation of confidential commercial information. A submitter of confidential commercial information must use good faith efforts to designate by appropriate markings, at the time of submission, any portion of its submission that it considers to be protected from disclosure under Exemption 4. These designations expire 10 years after the date of the submission unless the submitter requests and provides justification for a longer designation period.
(c) When notice to submitters is required.
1. (1) The FMCS will promptly notify the submitter in writing whenever such confidential commercial information is requested under the FOIA and the Agency determines that it may be required to disclose the information, provided:
  1. (i) The requested information has been designated in good faith by the submitter as information considered protected from disclosure under Exemption 4; or
  2. (ii) The FMCS has a reason to believe that the requested information may be protected from disclosure under Exemption 4, but has not yet made that determination.
2. (2) The notice must either describe the commercial information requested or include a copy of the requested records or portions of records containing the information. In cases involving a voluminous number of submitters, the Agency may post or publish a notice in a place or manner reasonably likely to inform the submitters of the proposed disclosure, instead of sending individual notifications.
(d) Exceptions to submitter notice requirements. The notice requirements of this section do not apply if:
1. (1) The Agency determines that the information is exempt under the FOIA, or the information has been lawfully published or has been officially made available to the public;
2. (2) Disclosure of the information is required by a statute other than the FOIA or by a regulation issued in accordance with the requirements of Executive Order 12600 of June 23, 1987; or
3. (3) The designation made by the submitter appears obviously frivolous.
(e) Opportunity to object to disclosure.
1. (1) The FMCS must specify a reasonable time period within which the submitter must respond to the notice referenced in paragraph (c) of this section.
2. (2) If a submitter has any objections to disclosure, it should provide the Agency a detailed written statement that specifies all grounds for withholding the particular information under any exemption of the FOIA. In order to rely on Exemption 4 as the basis for nondisclosure, the submitter must explain why the information constitutes a trade secret or commercial or financial information that is privileged or confidential.
3. (3) A submitter who fails to respond within the time period specified in the notice will be considered to have no objection to disclosure of the information. The FMCS is not required to consider any information received after the date of any disclosure decision. Any information provided by a submitter under this subpart may itself be subject to disclosure under the FOIA.
(f) Analysis of objections. The Agency must consider a submitter's objections and specific grounds for nondisclosure in deciding whether to disclose the requested information.
(g) Notice of intent to disclose. Whenever the FMCS decides to disclose information over the objection of a submitter, it must provide the submitter written notice, which must include:
1. (1) A statement of the reasons why each of the submitter's disclosure objections was not sustained;
2. (2) A description of the information to be disclosed or copies of the records as the Agency intends to release them; and
3. (3) A specified disclosure date, which must be within a reasonable time after the notice.
(h) Notice of FOIA lawsuit. Whenever a requester files a lawsuit seeking to compel the disclosure of confidential commercial information, the Agency must promptly notify the submitter.
(i) Requester notification. The Agency must notify the requester whenever it provides the submitter with notice and an opportunity to object to disclosure; whenever it notifies the submitter of its intent to disclose the requested information; and whenever a submitter files a lawsuit to prevent the disclosure of the information.
