48 CFR § 3.104-4 - Disclosure, protection, and marking of contractor bid or proposal information and source selection information.
(a) Except as specifically provided for in this subsection, no person or other entity may disclose contractor bid or proposal information or source selection information to any person other than a person authorized, in accordance with applicable agency regulations or procedures, by the agency head or the contracting officer to receive such information.
(c) Individuals unsure if particular information is source selection information, as defined in 2.101, should consult with agency officials as necessary. Individuals responsible for preparing material that may be source selection information as described at paragraph (10) of the “source selection information” definition in 2.101 must mark the cover page and each page that the individual believes contains source selection information with the legend “Source Selection Information - See FAR 2.101 and 3.104.” Although the information in paragraphs (1) through (9) of the definition in 2.101 is considered to be source selection information whether or not marked, all reasonable efforts must be made to mark such material with the same legend.
(d) Except as provided in paragraph (d)(3) of this subsection, the contracting officer must notify the contractor in writing if the contracting officer believes that proprietary information, contractor bid or proposal information, or information marked in accordance with 52.215-1(e) has been inappropriately marked. The contractor that has affixed the marking must be given an opportunity to justify the marking.
(1) If the contractor agrees that the marking is not justified, or does not respond within the time specified in the notice, the contracting officer may remove the marking and release the information.
(2) If, after reviewing the contractor's justification, the contracting officer determines that the marking is not justified, the contracting officer must notify the contractor in writing before releasing the information.
(3) For technical data marked as proprietary by a contractor, the contracting officer must follow the procedures in 27.404-5.
(e) This section does not restrict or prohibit -
(1) A contractor from disclosing its own bid or proposal information or the recipient from receiving that information;
(2) The disclosure or receipt of information, not otherwise protected, relating to a Federal agency procurement after it has been canceled by the Federal agency, before contract award, unless the Federal agency plans to resume the procurement;
(3) Individual meetings between a Federal agency official and an offeror or potential offeror for, or a recipient of, a contract or subcontract under a Federal agency procurement, provided that unauthorized disclosure or receipt of contractor bid or proposal information or source selection information does not occur; or
(4) The Government's use of technical data in a manner consistent with the Government's rights in the data.
(f) This section does not authorize -
(1) The withholding of any information pursuant to a proper request from the Congress, any committee or subcommittee thereof, a Federal agency, the Comptroller General, or an Inspector General of a Federal agency, except as otherwise authorized by law or regulation. Any release containing contractor bid or proposal information or source selection information must clearly identify the information as contractor bid or proposal information or source selection information related to the conduct of a Federal agency procurement and notify the recipient that the disclosure of the information is restricted by 41 U.S.C. chapter 21;
(2) The withholding of information from, or restricting its receipt by, the Comptroller General in the course of a protest against the award or proposed award of a Federal agency procurement contract;
(3) The release of information after award of a contract or cancellation of a procurement if such information is contractor bid or proposal information or source selection information that pertains to another procurement; or
(4) The disclosure, solicitation, or receipt of bid or proposal information or source selection information after award if disclosure, solicitation, or receipt is prohibited by law. (See 3.104-2(b)(5) and subpart 24.2.)
