    FAR 19.703Eligibility requirements for participating in the program.

    Plain-English Summary

    FAR 19.703 explains who is eligible to be counted as a subcontractor for federal subcontracting program purposes and how that eligibility is established, challenged, and documented. It covers the basic rule that a subcontractor must represent itself as a qualifying small business or socioeconomic category concern, including small business, veteran-owned small business, service-disabled veteran-owned small business, HUBZone small business, small disadvantaged business, or women-owned small business, and it ties those representations to the applicable SBA definitions and size standards. It also explains how a prime contractor may rely on a subcontractor’s written representations or SAM representations, when the prime may question those representations, and that the prime cannot force SAM as the only method of representation. The section further addresses protest procedures for challenging size status and special counting rules for Alaska Native Corporations and Indian tribes, including designation of which contractor gets subcontracting-goal credit and the timing for written designation. Finally, it points to the separate protest procedures for HUBZone socioeconomic status challenges. In practice, this section matters because it determines whether subcontract dollars can be credited toward subcontracting goals, what documentation a prime can rely on, and how disputes over status are handled.

    Key Rules

    Eligible subcontractor statuses

    To be eligible under the program, a subcontractor must represent itself as one of the listed categories: small business, veteran-owned small business, service-disabled veteran-owned small business, HUBZone small business, small disadvantaged business, or women-owned small business. The concern must meet the applicable definition in FAR 2.101 and 19.001, and for subcontracting purposes a concern is small only if it does not exceed the size standard for the NAICS code the prime determines best describes the subcontracted product or service.

    Written representations may be relied on

    A prime contractor may accept a subcontractor’s written representation of size and socioeconomic status unless it has reason to question the representation. The representation must state that the subcontractor’s status is current, accurate, and complete as of the date of the subcontract offer.

    SAM representations are optional

    A prime contractor may also accept a subcontractor’s SAM representation if the subcontractor is registered in SAM and states that the SAM size and socioeconomic status data are current, accurate, and complete as of the subcontract offer date. However, the prime contractor may not require SAM as the only method for making size or socioeconomic status representations for a subcontract.

    Good-faith reliance protects primes

    A prime contractor acting in good faith is not liable for a subcontractor’s misrepresentation of size or socioeconomic status, consistent with the cited SBA regulations. This rule encourages reasonable reliance while preserving the ability to challenge questionable claims.

    Size protests are allowed

    The contractor, the contracting officer, or any other interested party may challenge a subcontractor’s size status by filing a protest under the SBA size protest procedures in 13 CFR 121.1001 through 121.1008.

    ANC and Indian tribe counting rules

    Subcontracts awarded to an Alaska Native Corporation or Indian tribe count toward small business and small disadvantaged business subcontracting goals regardless of the ANC’s or tribe’s size or SBA certification status. If there are lower-tier subcontractors between the prime and the ANC or tribe, the ANC or tribe must designate which contractor gets credit, and the designation must be shared within 30 days.

    Default designation if no notice

    If the contracting officer does not receive the ANC’s or Indian tribe’s written designation within 30 days after subcontract award, the contractor that directly awarded the subcontract to the ANC or tribe is treated as the designated contractor for goal-credit purposes.

    HUBZone protests follow separate rules

    Challenges to the socioeconomic status of a HUBZone small business concern must be filed under the specific HUBZone protest procedures in 13 CFR 126.801, not the general size protest procedures.

    Responsibilities

    Contractor / Prime Contractor

    Determine the NAICS code that best describes the subcontracted product or service; decide whether there is reason to question a subcontractor’s representation; accept and rely on written or SAM representations when appropriate; avoid requiring SAM as the only representation method; act in good faith when relying on subcontractor status; and, where applicable, track ANC or Indian tribe designation letters for subcontracting-goal credit.

    Subcontractor

    Represent itself accurately as a qualifying small business or socioeconomic category concern only if it meets the applicable definition and size standard; ensure written or SAM representations are current, accurate, and complete as of the subcontract offer date; and, if an ANC or Indian tribe, provide written designation of which contractor may count the subcontract toward subcontracting goals.

    Contracting Officer

    Receive and consider protests or challenges when filed; monitor ANC or Indian tribe designation issues when relevant; and apply the correct protest framework, including the special HUBZone protest procedures where applicable.

    Interested Party

    File a size protest or status challenge when there is a basis to question a subcontractor’s representation, using the proper SBA procedures and deadlines.

    ANC or Indian Tribe

    Ensure subcontracts are counted correctly toward small business and SDB goals; designate the appropriate contractor(s) to receive credit when there are intervening subcontract tiers; provide written designation to the contracting officer, prime contractor, and intermediate subcontractors within 30 days; and, if designating more than one contractor, allocate only portions that do not exceed the total subcontract value.

    SBA / Protest Process

    Administer the cited size and HUBZone protest procedures and the related regulatory framework for determining status challenges.

    Practical Implications

    1

    Primes can usually rely on subcontractor status statements, but only if they have no reason to doubt them; red flags should trigger follow-up before counting the subcontract toward goals.

    2

    The NAICS code matters for subcontracting eligibility because small-business status is measured against the size standard for the code the prime believes best fits the subcontracted work.

    3

    SAM is a permitted source of status information, but primes cannot force subcontractors to use SAM just to make size or socioeconomic representations.

    4

    ANC and Indian tribe subcontracts have special counting rules that can override ordinary status concerns, so contractors should watch for designation letters and the 30-day deadline.

    5

    If a status challenge arises, using the wrong protest procedure is a common mistake; HUBZone challenges follow a separate process from general size protests.

    Official Regulatory Text

    (a) Except as provided in paragraph (c) of this section, to be eligible as a subcontractor under the program, a concern must represent itself as a small business, veteran-owned small business, service-disabled veteran-owned small business, HUBZone small business, small disadvantaged business, or women-owned small business concern. (1) To represent itself as a small business, veteran-owned small business, service-disabled veteran-owned small business, HUBZone small business, small disadvantaged business, or women-owned small business concern, a concern must meet the appropriate definition (see 2.101 and 19.001 ). For subcontracting purposes, a concern is small if it does not exceed the size standard for the NAICS code that the prime contractor determines best describes the product or service being acquired by the subcontract. (2) (i) Unless the prime contractor has reason to question the representation, it may accept a subcontractor's written representations of its size and socioeconomic status as a small business, small disadvantaged business, veteran-owned small business, service-disabled veteran-owned small business, HUBZone small business, or a women-owned small business, if the subcontractor represents that the size and socioeconomic status representation with its offer are current, accurate, and complete as of the date of the offer for the subcontracts; or (ii) Unless the prime contractor has reason to question the representation, it may accept a subcontractor's representation of its size and socioeconomic status as a small business, small disadvantaged business, veteran-owned small business, service-disabled veteran-owned small business, HUBZone small business, or a women-owned small business in the System for Award Management (SAM) if– (A) The subcontractor is registered in SAM; and (B) The subcontractor represents that the size and socioeconomic status representations made in SAM are current, accurate and complete as of the date of the offer for the subcontract. (iii) The prime contractor may not require the use of SAM for the purposes of representing size or socioeconomic status in connection with a subcontract. (iv) In accordance with 13 CFR 121.411, 126.900, 127.700, and 128.600, a prime contractor acting in good faith is not liable for misrepresentations made by its subcontractors regarding the subcontractor's size or socioeconomic status. (b) The contractor, the contracting officer, or any other interested party can challenge a subcontractor's size status representation by filing a protest, in accordance with 13 CFR 121.1001 through 121.1008. (c) (1) In accordance with 43 U.S.C. 1626 , the following procedures apply: (i) Subcontracts awarded to an ANC or Indian tribe shall be counted towards the subcontracting goals for small business and small disadvantaged business (SDB) concerns, regardless of the size or Small Business Administration certification status of the ANC or Indian tribe. (ii) Where one or more subcontractors are in the subcontract tier between the prime contractor and the ANC or Indian tribe, the ANC or Indian tribe shall designate the appropriate contractor(s) to count the subcontract towards its small business and small disadvantaged business subcontracting goals. (A) In most cases, the appropriate contractor is the contractor that awarded the subcontract to the ANC or Indian tribe. (B) If the ANC or Indian tribe designates more than one contractor to count the subcontract toward its goals, the ANC or Indian tribe shall designate only a portion of the total subcontract award to each contractor. The sum of the amounts designated to various contractors cannot exceed the total value of the subcontract. (C) The ANC or Indian tribe shall give a copy of the written designation to the contracting officer, the prime contractor, and the subcontractors in between the prime contractor and the ANC or Indian tribe within 30 days of the date of the subcontract award. (D) If the contracting officer does not receive a copy of the ANC's or the Indian tribe’s written designation within 30 days of the subcontract award, the contractor that awarded the subcontract to the ANC or Indian tribe will be considered the designated contractor. (2) A contractor acting in good faith may rely on the written representation of an ANC or an Indian tribe as to the status of the ANC or Indian tribe unless an interested party challenges its status or the contracting officer has independent reason to question its status. In the event of a challenge of a representation of an ANC or Indian tribe, the interested parties shall follow the procedures at 26.103 (b) through (e). (d) Protests challenging the socioeconomic status of a HUBZone small business concern must be filed in accordance with 13 CFR 126.801 .
