FAR 52.209-6—Protecting the Government's Interest When Subcontracting With Contractors Debarred, Suspended, Proposed for Debarment, or Voluntarily Excluded.
Plain-English Summary
FAR 52.209-6 addresses how contractors must protect the Government’s interests when they plan to subcontract with firms that are debarred, suspended, proposed for debarment, or voluntarily excluded. It covers the definition of a commercially available off-the-shelf (COTS) item, the basic prohibition on subcontracting with excluded parties absent a compelling reason, the requirement to obtain written disclosure from proposed subcontractors about their exclusion status, the requirement to notify the Contracting Officer before entering into a covered subcontract with an excluded party, and the flowdown of the clause to certain lower-tier subcontracts. In practice, the clause is a risk-control tool: it helps agencies prevent taxpayer funds from flowing to parties the Government has determined should not receive federal business, while still allowing limited exceptions when there is a documented compelling reason. The clause also distinguishes COTS subcontracts from other subcontracts, because COTS transactions are generally exempt from the clause’s core restrictions. For contractors, this means they must screen subcontractors, document exclusion status, maintain internal controls, and be prepared to justify any decision to subcontract with an excluded entity. For contracting officers, it provides a basis to monitor subcontracting risk and ensure the prime contractor has procedures to protect the Government’s interests.
Key Rules
COTS exception applies
The clause does not apply to subcontracts for commercially available off-the-shelf items. The definition is narrow: the item must be a commercial product, sold in substantial quantities in the commercial marketplace, and offered to the Government without modification in the same form as sold commercially.
No covered subcontracting without reason
Except for COTS subcontracts, the contractor may not enter into a subcontract above the FAR 9.405-2(b) threshold with a debarred, suspended, or proposed-for-debarment contractor unless there is a compelling reason. This rule reflects the Government’s policy of limiting business with excluded parties.
Written status disclosure required
For each proposed subcontractor above the threshold, other than a COTS supplier, the contractor must require a written disclosure stating whether the subcontractor or its principals are debarred, suspended, proposed for debarment, or voluntarily excluded at the time of award.
Advance notice to CO required
Before entering into a covered subcontract with an excluded party, a corporate officer or designee must notify the Contracting Officer in writing. The notice must identify the subcontractor, explain the contractor’s knowledge of the exclusion basis, state the compelling reason for the subcontract, and describe the systems and procedures used to protect the Government’s interests.
Flowdown is mandatory in many subcontracts
Unless the prime contract is for commercial products or commercial services, the contractor must include the clause in covered subcontracts that exceed the threshold and are not for COTS items. The flowdown must be appropriately modified to identify the parties at the lower tier.
Threshold is tied to FAR 9.405-2(b)
The clause uses the subcontract dollar threshold specified in FAR 9.405-2(b) as of the date of subcontract award. Contractors must check the current threshold at the time they award the subcontract, not rely on an older contract value or outdated benchmark.
Responsibilities
Contracting Officer
Review and monitor contractor notices involving proposed subcontracts with excluded parties, assess whether the contractor has provided the required information, and determine whether the Government’s interests are adequately protected. The CO also relies on the clause to ensure the prime contractor has appropriate subcontracting controls and flowdown practices.
Contractor
Screen proposed subcontractors, require written disclosure of exclusion status, avoid entering covered subcontracts with excluded parties unless there is a compelling reason, notify the Contracting Officer in writing before doing so, and maintain systems and procedures that protect the Government’s interests.
Corporate Officer or Designee
Provide the required written notice to the Contracting Officer before award of a covered subcontract with an excluded party. The notice must include the subcontractor’s name, the contractor’s knowledge of the exclusion basis, the compelling reason for the subcontract, and the protective systems and procedures in place.
Proposed Subcontractor
Disclose in writing whether it or its principals are debarred, suspended, proposed for debarment, or voluntarily excluded when the subcontract exceeds the applicable threshold and is not for a COTS item.
Prime Contractor’s Subcontract Management Staff
Implement screening, document retention, clause flowdown, and escalation procedures so that exclusion status is checked before award and any required notice to the Contracting Officer is timely and complete.
Practical Implications
This clause requires real-time exclusion screening before subcontract award; relying on an old SAM check or a one-time vendor approval process is a common mistake.
The COTS exception is often misunderstood. If the item is not truly a COTS item under the clause’s definition, the subcontract may still be subject to the exclusion restrictions and flowdown requirements.
Contractors should document the basis for any ‘compelling reason’ carefully, because the clause does not define that term and the Government may scrutinize the justification if an excluded party is used.
The written notice to the Contracting Officer is not optional when a covered excluded subcontractor is used; failing to notify can create compliance issues even if the contractor believed the subcontract was justified.
Flowdown must be handled deliberately, especially in non-commercial contracts. Missing the clause in a required lower-tier subcontract can leave the prime without the contractual leverage needed to enforce exclusion screening and reporting.

(c) The Contractor shall require each proposed subcontractor whose subcontract will exceed the threshold specified in FAR 9.405-2 (b) on the date of subcontract award, other than a subcontractor providing a commercially available off-the-shelf item, to disclose to the Contractor, in writing, whether as of the time of award of the subcontract, the subcontractor, or its principals, is or is not debarred, suspended, proposed for debarment, or voluntarily excluded, by the Federal Government.
