48 C.F.R. § 9.405 : Federal Acquisition Regulations System — FEDERAL ACQUISITION REGULATION — ACQUISITION PLANNING — CONTRACTOR QUALIFICATIONS — DEBARMENT, SUSPENSION, AND INELIGIBILITY — Effect of listing

(a) Contractors debarred, suspended, or proposed for debarment are excluded from receiving contracts, and agencies shall not solicit offers from, award contracts to, or consent to subcontracts with these contractors, unless the agency head determines that there is a compelling reason for such action ( see 9.405-1(b), 9.405-2, 9.406-1(c), 9.407-1(d), and 23.506(e)). Contractors debarred, suspended, or proposed for debarment are also excluded from conducting business with the Government as agents or representatives of other contractors.
(b) Contractors and other entities that have an active exclusion record in SAM because they have been declared ineligible on the basis of statutory or other regulatory procedures are excluded from receiving contracts, and if applicable, subcontracts, under the conditions and for the period set forth in the statute or regulation. Agencies shall not solicit offers from, award contracts to, or consent to subcontracts with these contractors under those conditions and for that period.
(c) Agencies shall not enter into, renew, or extend contracts with contractors that have been declared ineligible pursuant to 22 U.S.C. 2593e.
(d) Contractors debarred, suspended, or proposed for debarment are excluded from acting as individual sureties (see part 28).
(e)
(1) After the opening of bids or receipt of proposals or quotes, the contracting officer shall review the exclusion records in SAM.
(2) Bids received from any listed contractor in response to an invitation for bids shall be entered on the abstract of bids, and rejected unless the agency head determines in writing that there is a compelling reason to consider the bid.
(3) Proposals, quotations, or offers received from any listed contractor shall not be evaluated for award or included in the competitive range, nor shall discussions be conducted with a listed offeror during a period of ineligibility, unless the agency head determines, in writing, that there is a compelling reason to do so. If the period of ineligibility expires or is terminated prior to award, the contracting officer may, but is not required to, consider such proposals, quotations, or offers.
(4) Immediately prior to award, the contracting officer shall again review the the exclusion records in SAM to ensure that no award is made to a listed contractor.
