(a) Definition. A class set-aside is an item (or service), a group of related items under a Federal Supply Class (FSC), or a whole FSC set aside for exclusive small business participation on more than a one-time basis. If the item or group of items constitute only a small portion of an FSC, this definition still applies.

(b) Determinations. If the contracting officer has procurement responsibility for the class of items or services involved, prepare the determination required by FAR 19.503. The determination can apply to either a total or partial set-aside.
