PSC E1BC

Overview

The Product Service Code (PSC) is a standardized taxonomy the U.S. government uses in FPDS/SAM to classify what products and services are procured, improving the tracking, analysis, and reporting of federal spend. PSCs are governed by the PSC Manual on Acquisition.gov and populate FPDS data element 8A, “Product or Service Code.” ¹

Per the PSC Manual, E1BC denotes “Purchase of Radar and Navigational Facilities.” It sits within Category E1 (Purchase of Structures and Facilities) and is used when the government acquires facility-level radar or navigational assets as real property/structures, as distinct from constructing, leasing, operating, maintaining, or repairing them. ²

What this PSC covers

• Purchase transactions for facility-level radar installations categorized as structures/facilities, not equipment-only buys. ²
• Purchase transactions for facility-level navigational facilities categorized as structures/facilities. ²
• Use for outright acquisition of these facilities; do not use for construction, lease/rental, operation, maintenance, repair, or alteration—see Y1BC, X1BC, M1BC, Z1BC, and Z2BC. ²
• Equipment-only purchases (e.g., radar sets or radio navigation gear without facilities) typically use product PSCs such as 5840, 5841, 5825, or 5826, not E1BC. ²
• Detailed inclusions/exclusions and examples: Not specified by official sources ¹

Adjacent lifecycle PSCs and boundaries

E1-family codes cover purchase of structures/facilities. For radar and navigational facilities specifically: E1BC = purchase; X1BC = lease/rental; Y1BC = construction; M1BC = operation; Z1BC = maintenance; Z2BC = repair/alteration. Equipment-only radar/navigation buys are generally coded under Group 58 product PSCs rather than E1BC. ²

Frequently asked questions

• What does PSC E1BC mean? E1BC is the PSC for “Purchase of Radar and Navigational Facilities,” within Category E1 (Purchase of Structures and Facilities). Use it when the government acquires these facilities as structures/real property, not for building, leasing, operating, maintaining, or repairing them. ²

• When should E1BC be used versus Y1BC, Z1BC, Z2BC, X1BC, or M1BC? Use E1BC for purchase. Choose Y1BC for construction, X1BC for lease/rental, M1BC for operations, Z1BC for maintenance, and Z2BC for repair/alteration. ²

• How should equipment-only buys (no facility) be coded? Equipment-only acquisitions generally use Group 58 product PSCs such as 5840 (Radar Equipment, Except Airborne), 5841 (Radar Equipment, Airborne), and 5825/5826 (Radio Navigation Equipment), not facility purchase code E1BC. ²

• Where is the PSC captured and viewed in federal procurement data? PSCs populate FPDS/SAM contract data, and the SAM.gov Contract Award Data domain provides public access to search and reports. FPDS remains the authoritative source for searchable award data during the migration to SAM.gov’s data services. ³

• Is there an official PSC-to-NAICS mapping specific to E1BC? Not specified by official sources ¹
