FAR and DFARS › FAR Part 9: Contractor Qualifications › Subpart 9.4
FAR 9.405-2 Restrictions on subcontracting.
The codified text (eCFR, as of 2026-10-02). Under the Revolutionary FAR Overhaul ↗, agencies follow class deviations with new text for many parts while the formal rules go through the Federal Register: check the solicitation and your contract's clauses, which rule.
In plain English
This section restricts subcontracting with contractors that are debarred, suspended, proposed for debarment, or voluntarily excluded. It matters because a contractor generally cannot enter into a subcontract over $45,000 with such a party unless there is a compelling reason, and it may need to notify the contracting officer in writing before doing so.
Applies to: Contractors awarding subcontracts subject to Government consent or the clause at 52.209-6
What it requires
- Do not enter into a subcontract in excess of $45,000, other than for a commercially available off-the-shelf item, with a debarred, suspended, proposed-for-debarment, or voluntarily excluded contractor unless there is a compelling reason.
- If intending to enter such a subcontract, have a corporate officer or designee notify the contracting officer in writing before entering into the subcontract.
- In the notice, provide the subcontractor's name, the contractor's knowledge of the reasons for the active exclusion record in SAM, the compelling reason(s) for doing business with the subcontractor, and the systems and procedures established to protect the Government's interests.

The text
(a) When a contractor debarred, suspended, proposed for debarment, or voluntarily excluded, is proposed as a subcontractor for any subcontract subject to Government consent (see subpart 44.2), contracting officers shall not consent to subcontracts with such contractors unless the agency head states in writing the compelling reasons for this approval action. (See 9.405 concerning declarations of ineligibility affecting subcontracting.)
(b) The Government suspends or debars contractors to protect the Government's interests. Contractors are prohibited from entering into any subcontract in excess of $45,000, other than a subcontract for a commercially available off-the-shelf item, with a contractor that has been debarred, suspended, proposed for debarment, or voluntarily excluded, unless there is a compelling reason to do so. If a contractor intends to enter into a subcontract in excess of $45,000, other than a subcontract for a commercially available off-the-shelf item, with a party that is debarred, suspended, proposed for debarment, or voluntarily excluded, as evidenced by the party's having an active exclusion record in SAM (see 9.404), a corporate officer or designee of the contractor is required by operation of the clause at 52.209-6, Protecting the Government's Interest when Subcontracting with Contractors Debarred, Suspended, Proposed for Debarment, or Voluntarily Excluded, to notify the contracting officer, in writing, before entering into such subcontract. For contracts for the acquisition of commercial products, the notification requirement applies only for first-tier subcontracts. For all other contracts, the notification requirement applies to subcontracts at any tier. The notice must provide the following:
(1) The name of the subcontractor;
(2) The contractor's knowledge of the reasons for the subcontractor having an active exclusion record in SAM;
(3) The compelling reason(s) for doing business with the subcontractor notwithstanding its having an active exclusion record in SAM; and
(4) The systems and procedures the contractor has established to ensure that it is fully protecting the Government's interests when dealing with such subcontractor in view of the specific basis for the party's debarment, suspension, proposed debarment, or voluntary exclusion.
(c) The contractor's compliance with the requirements of 52.209-6 will be reviewed during Contractor Purchasing System Reviews (see subpart 44.3).
