FAR Part 9 is the part of the Federal Acquisition Regulation that decides who the government may buy from. It sets the rules for finding a contractor responsible, for excluding contractors through debarment and suspension, for qualification and first-article testing, and for organizational conflicts of interest. This guide maps the part subpart by subpart, as described on acquisition.gov on 2026-10-29, so you can tell which subpart answers which question.
What FAR Part 9 is and who it governs
The scope paragraph at 9.000 says the part “prescribes policies, standards, and procedures pertaining to prospective contractors’ responsibility”, and then lists debarment, suspension and ineligibility, qualified products, first article testing, contractor team arrangements, defense production and research and development pools, and organizational conflicts of interest. It is run by the agency contracting officer on each acquisition and, for exclusions, by the agency suspending and debarring official; GSA operates the System for Award Management (SAM) where exclusion records are kept (9.404).
Part 9 governs federal procurement contracts. Grants and cooperative agreements follow a different rulebook; the guide on federal contracts vs grants for university research explains where that line falls, and the SAM exclusion record described below is the point where the two systems touch, because a SAM record can list entities excluded under the nonprocurement common rule as well as under the FAR (9.404(b)(1)).
The subparts at a glance
The official table of contents for Part 9, as described on acquisition.gov on 2026-10-29, lists seven subparts. The table pairs each one with the question it answers.
| Subpart | Question it answers | What the official text says |
|---|---|---|
| 9.1 Responsible Prospective Contractors | Is this offeror fit to receive an award? | 9.100: prescribes “policies, standards, and procedures for determining whether prospective contractors and subcontractors are responsible.” |
| 9.2 Qualifications Requirements | Must a product or source be tested and listed before award? | 9.200: implements 10 U.S.C. 3243 and 41 U.S.C. 3311; defines qualified bidders, manufacturers and products lists. |
| 9.3 First Article Testing and Approval | Must the first unit be tested before production continues? | 9.302: testing “ensures that the contractor can furnish a product that conforms to all contract requirements for acceptance.” |
| 9.4 Debarment, Suspension, and Ineligibility | Is this contractor excluded, and for how long? | 9.400: governs debarment and suspension by agencies, the SAM listing of excluded parties, and the consequences of the listing. |
| 9.5 Organizational and Consultant Conflicts of Interest | Could this contractor’s other roles bias its work or give it an unfair advantage? | 9.500: prescribes responsibilities, general rules and procedures for identifying, evaluating and resolving organizational conflicts of interest. |
| 9.6 Contractor Team Arrangements | How may companies team up to pursue a government contract? | 9.601: a partnership or joint venture acting as a potential prime, or a prime that agrees with others to act as its subcontractors on a specified contract. |
| 9.7 Defense Production Pools and Research and Development Pools | How do approved pools of concerns bid on defense production or research and development contracts? | 9.701: defines a pool as a group of concerns that associated to obtain and perform such contracts under an approved agreement. |
Responsibility determinations (Subpart 9.1)
The core rule is at 9.103. Purchases and awards go to “responsible prospective contractors only” (9.103(a)), and “No purchase or award shall be made unless the contracting officer makes an affirmative determination of responsibility” (9.103(b)). If information clearly showing responsibility is absent, the contracting officer makes a determination of nonresponsibility. For a small business the contracting officer follows the certificate-of-competency procedures of Subpart 19.6.
The burden sits with the offeror: 9.103(c) states that “A prospective contractor must affirmatively demonstrate its responsibility”, including, when necessary, that of its proposed subcontractors. It also says an award on lowest evaluated price alone can be false economy, so the lowest offer does not have to win. The responsibility certifications offerors make are covered at 9.104-5, which ties an affirmative answer on the representation at 52.209-5 to additional information requests and to notice to the official who handles debarment. The seven general standards in 9.104-1 are explained in our guide to FAR 9.104 responsibility determinations; this page does not repeat them.
Qualification requirements and first article testing (Subparts 9.2 and 9.3)
Subpart 9.2 applies only when an agency has set a qualification requirement. Before establishing one, the agency head or designee must prepare a written justification stating why it is necessary and why it must be shown before award, estimating the testing cost to the offeror, and listing every requirement to be met (9.202(a)(1)). When an acquisition is subject to a qualification requirement, the contracting officer inserts the clause at 52.209-1 (9.206-2).
Subpart 9.3 is a contract-level control. Before requiring testing and approval, the contracting officer considers the impact on cost or delivery time, the risk to the government of skipping the test, and the availability of other, less costly ways to ensure quality (9.302). Approval is the contracting officer’s written notification accepting the test results (9.301). Before first article approval, buying materials or starting production is normally at the contractor’s sole risk (9.305).
Debarment, suspension and ineligibility (Subpart 9.4)
Subpart 9.4 is the exclusion system. Its policy statement (9.402) says agencies solicit offers from, award contracts to, and consent to subcontracts with responsible contractors only, and that debarment and suspension are discretionary actions imposed to protect the government, “not for purposes of punishment.”
Debarment versus suspension
Debarment is a period-limited exclusion: it “shall be for a period commensurate with the seriousness of the cause(s). Generally, debarment should not exceed 3 years” (9.406-4(a)(1)), with stated exceptions, such as up to 5 years for violations of the Drug-Free Workplace provisions. Suspension is the interim tool: “a serious action to be imposed on the basis of adequate evidence, pending the completion of an investigation or legal proceedings” when immediate action is needed to protect the government’s interest (9.407-1). If a suspension comes before a debarment, the suspension period counts toward the debarment period (9.406-4(a)(2)).
What a listing does
Contractors that are debarred, suspended, proposed for debarment or voluntarily excluded are excluded from receiving contracts, and agencies must not solicit offers from them, award to them, or consent to subcontracts with them unless the agency head finds a compelling reason (9.405(a)). They are also barred from acting as agents or representatives of other contractors. For subcontracts, 9.405-2(b) says contractors are prohibited from entering into a subcontract above $45,000, other than for a commercially available off-the-shelf item, with such a party unless there is a compelling reason. The exclusion record in SAM carries the entity name, the acting agency, the cause, the effect of the action and the termination date for each listing (9.404(b)). To run the check in practice, see debarment and exclusion screening for vendors, the SAM.gov definition and the guide to FAPIIS suspension and debarment integrity checks.
Organizational conflicts of interest (Subpart 9.5)
Subpart 9.5 is about the contractor as an organization, which is different from an individual’s conflict of interest. Section 9.505 gives the two underlying principles: “Preventing the existence of conflicting roles that might bias a contractor’s judgment” and “Preventing unfair competitive advantage.” An unfair competitive advantage exists, for example, where a competing contractor holds proprietary information obtained from a government official without authorization, or source selection information that other competitors lack.
The contracting officer is told to analyze planned acquisitions to identify potential conflicts “as early in the acquisition process as possible” and to “Avoid, neutralize, or mitigate significant potential conflicts before contract award” (9.504(a)). An agency head or designee can waive a rule of the subpart only in writing, setting out the extent of the conflict, and the authority cannot be delegated below the head of a contracting activity (9.503). Section 9.505 also says conflicts can arise in situations the examples do not cover, so each situation is judged on its facts.
Typical phases where Part 9 shows up
Part 9 is applied at different points of one acquisition. The order below describes where each subpart enters, not a calendar.
- Before the solicitation: the contracting officer reviews planned acquisitions for organizational conflicts (9.504) and, where a qualification requirement exists, checks that enough qualified sources exist for competition (9.206-3).
- At offer: the offeror makes the responsibility representations and certifications (9.104-5), and exclusion records in SAM (9.404) show which contractors are excluded.
- At award: the contracting officer makes the affirmative determination of responsibility (9.103(b)).
- During performance: first article testing and approval apply if the contract requires them (9.302), and subcontract consent rules apply to excluded parties (9.405-2).
- Any time: an agency may suspend or debar a contractor under Subpart 9.4, which changes its eligibility for new awards.
Common mistakes
- Treating Part 9 as a grants rule. It governs procurement contracts. Applying it to a grant application or a subaward mixes two systems.
- Assuming lowest price wins. 9.103(c) says award on lowest price alone can be false economy and the offeror must demonstrate responsibility.
- Reading suspension as a finding of guilt. 9.407-1 describes it as an interim action pending an investigation or legal proceedings.
- Assuming a debarment lasts exactly 3 years. 9.406-4 says “generally” 3 years, with listed exceptions and a period matched to the seriousness of the cause.
- Checking only the prime. 9.103(c) refers to the responsibility of proposed subcontractors, and 9.405-2 restricts subcontracts with excluded parties.
- Quoting an old section number. Part 9 text is revised through the FAR amendment process, and FAR overhaul guidance for Part 9 is published on acquisition.gov. Check which text your solicitation incorporates.

FAQ
What is FAR Part 9?
It is the Federal Acquisition Regulation part on contractor qualifications: responsibility determinations, qualification requirements, first article testing, debarment and suspension, organizational conflicts of interest, team arrangements, and defense and research and development pools.
Is FAR Part 9 about grants?
No. It governs federal procurement contracts. Grants and cooperative agreements are governed separately, although SAM exclusion records can include actions taken under the nonprocurement common rule (9.404(b)(1)).
How long does debarment last?
Generally not more than 3 years, matched to the seriousness of the cause, with listed exceptions such as up to 5 years for Drug-Free Workplace violations (9.406-4).
What is the difference between suspension and debarment?
Suspension is an interim action based on adequate evidence while an investigation or legal proceeding is pending (9.407-1). Debarment is a fixed-period exclusion (9.406-4). Suspension time counts toward any later debarment period.
What does an affirmative determination of responsibility mean?
It is the contracting officer’s finding, required before any purchase or award, that the prospective contractor is responsible (9.103(b)). Without clear information showing responsibility, the officer must make a determination of nonresponsibility.
