FAR 19.503 Reserves.
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 allows contracting officers, at their discretion, to reserve one or more awards for small businesses in multiple-award procurements using full and open competition. It applies when market research shows a total or partial set-aside is not feasible. It matters because it gives small businesses a chance at awards even when a full set-aside is not possible.
Applies to: Contracting officers conducting multiple-award procurements using full and open competition
Key terms: reserve · multiple-award procurements · full and open competition · total set-aside · partial set-aside

The text
(a) In accordance with section 1331 of the Small Business Jobs Act of 2010 (15 U.S.C. 644(r)(3)) and 13 CFR 125.2(e)(4), contracting officers may, at their discretion when conducting multiple-award procurements using full and open competition, reserve one or more contract awards for any of the small business concerns identified in 19.000(a)(3), when market research indicates—
(1) A total set-aside is not feasible because there is no reasonable expectation of receiving offers that are competitive in terms of fair market prices, quality, and delivery from at least two responsible small business concerns identified in 19.000(a)(3), that can perform the entire requirement; and
(2) A partial set-aside is not feasible because—
(i) The contracting officer is unable to divide the requirement into distinct portions; or
(ii) There is no reasonable expectation that at least two responsible small business concerns identified in 19.000(a)(3) can perform any portion of the requirement competitively in terms of fair market price, quality, and delivery.
(b) A reserve will result in one of the following:
(1) One or more contract awards to any one or more types of small business concerns identified in 19.000(a)(3).
(2) In the case of a solicitation of a bundled requirement that will result in a multiple-award contract, an award to one or more small businesses with a Small Business Teaming Arrangement.
(c) The specific program eligibility requirements identified in this part apply.
(d) The limitations on subcontracting and the nonmanufacturer rule (see 19.505) do not apply to reserves at the contract level, but shall apply to orders that are set aside or issued directly to one small business concern under 19.504(c)(1)(ii).
