What Does PSC AC66 Cover?

PSC AC66 (R&D- DEFENSE SYSTEM: ELECTRONICS/COMMUNICATION EQUIPMENT (MANAGEMENT/SUPPORT)) is assigned to contract actions where the primary deliverable involves r&d- defense system: electronics/communication equipment (management/support). Contracting officers assign this code when creating or modifying contract actions in the Federal Procurement Data System (FPDS), and it flows through to USASpending.gov where it becomes part of the public record of federal procurement activity.

Research and Development codes represent contracts for basic research, applied research, advanced technology development, and operational systems development. R&D contracts carry inherent uncertainty and often use cost-reimbursement contract types (FAR Part 16) rather than fixed-price arrangements. They are subject to additional oversight requirements under FAR Part 35.

Understanding R&D Code AC66

The first character of a PSC code indicates its broad category. Codes beginning with letters A through Z generally represent services and R&D, while codes beginning with numbers (1-9) represent products and supplies. PSC AC66 begins with "A," placing it in the r&d classification.

Federal agencies use PSC codes alongside NAICS codes to classify procurements. While NAICS codes describe the contractor's industry, PSC codes describe the product or service being purchased. A contractor with a single NAICS code may deliver goods or services across many different PSC codes. Understanding both classification systems is essential for identifying relevant contract opportunities and analyzing your competitive landscape.
