FAR 19.502—Setting aside acquisitions.

Requirements for setting aside acquisitions.

FAR 19.502-1 explains when a contracting officer must set aside an acquisition, or a class of acquisitions, for competition among small businesses. It covers two core policy bases for a set-aside: supporting the Nation’s productive capacity and defense-related needs, and ensuring a fair proportion of federal contracts goes to small business concerns. The section also ties the set-aside decision to the specific circumstances in FAR 19.502-2 and 19.502-3(a), which means the contracting officer must confirm that the applicable small-business set-aside conditions are met before restricting competition. In practice, this rule is one of the main entry points for small-business participation in federal procurement and helps agencies meet socioeconomic and industrial-base goals. The section also identifies important exceptions, including purchases at or below the micro-purchase threshold and purchases from mandatory sources under FAR Part 8, such as the Committee for Purchase From People Who Are Blind or Severely Disabled. For contracting officers, this means the set-aside analysis is not optional when the rule applies, but it must be applied in the right context and only after checking whether an exception removes the requirement.

Total small business set-asides.

FAR 19.502-2 establishes the core rule for total small business set-asides in federal acquisitions. It covers when supplies and services must be reserved for small business, the dollar thresholds that trigger the rule, the “rule of two” standard for deciding whether a set-aside is required, what happens when only one acceptable small business offer is received, and what to do when no acceptable small business offers are received. It also explains that acquisitions above the simplified acquisition threshold must be set aside only when there is a reasonable expectation of receiving offers from at least two responsible small business concerns at fair market prices, and it points contracting officers to FAR 19.203 for additional socioeconomic considerations. The section further clarifies that past acquisition history and market research matter, but are not the only factors in the analysis. For research and development acquisitions, it adds a special requirement to consider whether small businesses can provide the best scientific and technological sources consistent with the agency’s needs for cost, performance, and schedule. In practice, this section is the main decision point for whether an acquisition is competed as a total small business set-aside or left unrestricted, and it drives both market research and acquisition strategy.

Partial set-asides of contracts other than multiple-award contracts.

FAR 19.502-3 explains when and how a contracting officer may use a partial set-aside for small business participation in acquisitions other than multiple-award contracts. It covers the threshold conditions for using a partial set-aside, including market research showing that a total set-aside is not appropriate, the ability to divide the requirement into distinct portions, the inapplicability of simplified acquisition procedures, and the expectation that at least two responsible small business concerns can compete at fair market prices, quality, and delivery. It also requires that the acquisition be subject to the applicable small business program eligibility rules in FAR part 19 and that the resulting contract will not be a multiple-award contract. The section then addresses solicitation content: the contracting officer must identify which portions are set aside and which are not, and must explain how offers are to be submitted for the set-aside and non-set-aside portions. Finally, it establishes how offers from non-small businesses are treated on the set-aside portion and requires SBA size-determination procedures before rejecting an otherwise eligible offer based on size questions. In practice, this rule is about structuring a mixed procurement so small businesses get a fair opportunity on separable work while the agency still satisfies its full requirement efficiently and lawfully.

Partial set-asides of multiple-award contracts.

FAR 19.502-4 explains when and how a contracting officer may partially set aside portions of a multiple-award contract for small business participation. It covers the discretionary authority to reserve one or more portions of the requirement for eligible small business concerns, the threshold conditions that must be met before using a partial set-aside, and the special rule that this authority does not apply to construction. The section also requires the solicitation to clearly identify which portions are set aside and which are not, and to tell offerors how to submit offers for each portion. Finally, it addresses offer evaluation by requiring rejection of offers from firms that do not qualify as small business on the set-aside portion, while also protecting offerors from being rejected on size issues until SBA has made the required size determination. In practice, this provision gives agencies a flexible tool when a total set-aside is not suitable but some small business participation is still feasible, while ensuring the competition structure is clear and legally defensible.

Insufficient reasons for not setting aside an acquisition.

FAR 19.502-5 tells contracting officers what cannot, by itself, justify refusing to set aside an acquisition for small business. It covers eight common but insufficient reasons: a history of awarding many prior contracts to small businesses, inclusion on an Industrial Readiness Planning Program list, inclusion on a Qualified Products List, a short solicitation period of less than 30 days, a classified acquisition, the fact that small businesses already receive a fair share of agency contracts, an existing class small business set-aside by another contracting activity, and use of a brand name or equal description. The purpose of the rule is to prevent agencies from using convenience, administrative history, or procurement format as a substitute for the required small business set-aside analysis. In practice, the section reinforces that set-aside decisions must be based on the current acquisition and the applicable small business rules, not on generalized assumptions or unrelated program conditions. It also clarifies that some of these factors may still matter in limited circumstances, but they cannot alone support a decision not to set aside the procurement.

Setting aside a class of acquisitions for small business.

FAR 19.502-6 explains when an agency may establish a class of acquisitions as a small business set-aside instead of deciding set-aside status one procurement at a time. It covers class set-asides for selected products or services, including partial class set-asides, and ties them to the normal small business set-aside standards in FAR 19.502-1, 19.502-2, and 19.502-3(a). The rule also addresses how the class determination is made—either unilaterally or jointly—what must be included in the written determination, and how far the class set-aside reaches within the agency. Finally, it requires contracting officers to review each individual acquisition under the class set-aside for changed circumstances and allows withdrawal or modification when market conditions, requirements, or small business capability have materially changed. In practice, this section is meant to streamline recurring buys that are suitable for small business participation while still protecting the Government from using an outdated set-aside when the market or requirement has changed.

Inclusion of Federal Prison Industries, Inc.

FAR 19.502-7 addresses one narrow but important procurement rule: when an agency is using the competitive procedures described in FAR 8.602(a)(4), it must include Federal Prison Industries, Inc. (FPI) in the solicitation process and evaluate any offer FPI submits on time. The section exists to ensure FPI is not excluded from competition when the acquisition method triggers this requirement, and it reinforces the Government’s obligation to treat FPI as a potential source in the specified competitive setting. In practice, this means the contracting activity must make sure FPI receives the solicitation or otherwise has a fair opportunity to compete, and that its timely offer is considered along with other offers. The rule is procedural rather than substantive: it does not guarantee award to FPI, but it does require inclusion and consideration. For contracting officers and acquisition teams, the key significance is to avoid an avoidable competition defect by confirming whether the acquisition falls under FAR 8.602(a)(4) and, if so, documenting that FPI was included and any timely response was evaluated.

Rejecting Small Business Administration recommendations.

FAR 19.502-8 sets out the process for handling a contracting officer’s rejection of a Small Business Administration (SBA) recommendation, including the required written notice, the SBA’s right to appeal, the role of the SBA Procurement Center Representative (PCR), the contracting officer’s duty to suspend acquisition action during the appeal process, the review by the head of the contracting activity, the further appeal path to the agency head or Secretary of the department concerned, and the public-interest exception that allows the contracting officer to continue despite a request to suspend. In practice, this section is about preserving the SBA’s ability to advocate for small business participation while also giving the agency a controlled, time-bound process for resolving disagreements. It creates short deadlines for notice and appeal, which means both the contracting officer and SBA must act quickly or risk losing appeal rights or delaying the acquisition. It also requires documentation in the contract file, making the decision record important for oversight, protest defense, and internal review. For contractors, the rule matters because it can affect timing of award and performance when a small business recommendation is under dispute. For contracting officers, it is a procedural safeguard: if they reject SBA advice, they must follow the notice, suspension, and justification requirements exactly.

Withdrawing or modifying small business set-asides.

FAR 19.502-9 explains when and how a contracting officer may withdraw or modify a small business set-aside before award. It covers both total and partial set-asides, as well as unilateral and joint class set-asides, and it addresses the standard for doing so: the contracting officer must believe award under the set-aside would be detrimental to the public interest, such as when the price would exceed a fair market price. The section also sets out the required notice process, including written notice to the agency small business specialist and the SBA Procurement Center Representative (PCR), or the alternate contact if no PCR is assigned. If the small business specialist disagrees, the matter must be referred promptly to the SBA PCR for review. Finally, the contracting officer must document the decision with a written statement in the contract file. In practice, this rule protects the integrity of the small business program while allowing the Government to avoid awards that would not serve the public interest.

Automatic dissolution of a small business set-aside.

FAR 19.502-10 addresses what happens when a small business set-aside, or part of one, does not result in an award. It explains the automatic dissolution of the set-aside for the unawarded portion, meaning the government is no longer bound to keep that portion reserved for small business and may instead procure the remaining supplies or services through sealed bidding or negotiation, as appropriate. The section also requires the contracting officer, before reissuing a solicitation for the dissolved items, to make sure the delivery schedule is realistic in light of all relevant factors, including what small business concerns can actually perform. In practice, this provision prevents procurement delays from forcing an unrealistic small business competition and gives the agency a lawful path to complete the acquisition. It also protects the integrity of the acquisition process by requiring the contracting officer to reassess schedule feasibility rather than simply re-solicit the same requirement on the same terms. For contractors, it signals that a set-aside can disappear automatically for the unawarded portion if no award is made, and that the government may broaden the competition or change the acquisition approach for the remaining requirement.

Solicitation notice regarding administration of change orders for construction.

FAR 19.502-11 is a cross-reference provision that tells readers where to find the solicitation notice requirement for construction contracts involving the administration of change orders and the definitization of equitable adjustments. In practical terms, this section does not itself create a detailed substantive rule; instead, it points contracting personnel and offerors to FAR 36.211, which governs the notice that must be included in solicitations for construction when the Government may issue change orders and later definitize the resulting equitable adjustment. The topic matters because construction contracts often involve field changes, differing site conditions, design clarifications, and other modifications that can affect price, time, and performance. The notice requirement helps ensure offerors understand how change orders will be handled, how equitable adjustments will be negotiated and finalized, and what administrative process will apply after work changes are directed. For contractors, this affects pricing, risk allocation, and expectations about documentation and negotiation. For contracting officers, it is a solicitation-preparation requirement that supports transparency and reduces disputes over how change-order adjustments will be settled.
