(a) A class of acquisitions of selected products or services, or a portion of the acquisitions, may be set aside for exclusive participation by small business concerns if individual acquisitions in the class will meet the criteria in 19.502-1, 19.502-2, or 19.502-3(a). The determination to make a class small business set-aside shall not depend on the existence of a current acquisition if future acquisitions can be clearly foreseen.

(b) The determination to set aside a class of acquisitions for small business may be either unilateral or joint.

(c) Each class small business set-aside determination shall be in writing and must-

(1) Specifically identify the product(s) and service(s) it covers;

(2) Provide that the set-aside does not apply to any acquisition automatically set aside under 19.502-2(a).

(3) Provide that the set-aside applies only to the (named) contracting office(s) making the determination; and

(4) Provide that the set-aside does not apply to any individual acquisition if the requirement is not severable into two or more economic production runs or reasonable lots, in the case of a partial class set-aside.

(d) The contracting officer shall review each individual acquisition arising under a class small business set-aside to identify any changes in the magnitude of requirements, specifications, delivery requirements, or competitive market conditions that have occurred since the initial approval of the class set-aside. If there are any changes of such a material nature as to result in probable payment of more than a fair market price by the Government or in a change in the capability of small business concerns to satisfy the requirements, the contracting officer may withdraw or modify (see 19.502-9(a)) the unilateral or joint set-aside by giving written notice to the SBA PCR (or, if a PCR is not assigned, see 19.402(a)) stating the reasons.
