The Agriculture Acquisition Regulation (AGAR) prescribes policies and procedures that implement and supplement the Federal Acquisition Regulation (FAR), which is the primary regulation for use by all Federal Executive agencies in the acquisition of supplies and services with appropriated funds.

Agriculture Acquisition Regulation Advisories (1) communicate Department-wide policy and/or procedural guidance to contracting activities; (2) delegate to procurement officials authority to make determinations or to take action to implement the policies of the FAR or the AGAR; and, (3) establish internal policy and procedures on an interim basis, prior to incorporation in the AGAR or in a Departmental Directive.

Regulations, directives, notices, and policy decisions enable the procurement divisions to carry out the acquisition of supplies and services in support of USDA programs.
