49 C.F.R. § 33.53 — Types of allocation orders.
§ 33.53 Types of allocation orders. There are three types of allocation orders available for communicating allocation actions. These are: (a) Set-aside: An official action that requires a person to reserve materials, services, or facilities capacity in anticipation of the receipt of rated orders; (b) Directive: An official action that requires a person to take or refrain from taking certain actions in accordance with its provisions. For example, a directive can require a person to: stop or reduce production of an item; prohibit the use of selected materials, services, or facilities; or divert the use of materials, services, or facilities from one purpose to another; and (c) Allotment: An official action that specifies the maximum quantity of a material, service, or facility authorized for a specific use.
