PSC AN25

Overview

The Product and Service Code (PSC) system is a governmentwide taxonomy used to classify what the federal government buys so agencies can record, analyze, and report procurement activity in FPDS/SAM. The PSC Manual governs code definitions and usage across products, services, and research and development.¹
PSC AN25 denotes Health R&D Services—Health research and training—Expenses for R&D Facilities and Major Equipment. Within the R&D schema, the “5” in the fourth position identifies obligations for R&D facilities and major equipment; examples include construction of R&D facilities and acquisition or production of major movable R&D instruments used to execute health research and training programs.¹

What this PSC covers

• Capital construction or major improvement of facilities necessary to perform health-related R&D and training.¹
• Supporting infrastructure tied to R&D facilities, such as land, major fixed equipment, and essential utilities (e.g., sewer lines) required to conduct R&D.¹
• Acquisition, design, or production of major movable R&D instruments (e.g., mass spectrometers, DNA sequencers, research vessels) for use in health R&D activities.¹
• Programs devoted to purchasing or constructing R&D major equipment, generally at or above program scale (e.g., $1 million or more noted in the PSC Manual).¹
• Allocation of mixed-use construction, reporting only the portion directly related to R&D based on the facility’s R&D share of total square footage.¹
• Treatment of these obligations as a distinct “stage” of R&D within the PSC structure (stage code 5: Expenses for R&D Facilities and Major Equipment).¹

Common exclusions and edge cases

• Do not use AN25 for construction of non-R&D facilities (e.g., office-only buildings). Such construction is excluded from R&D Facilities and Major Equipment.¹
• Minor equipment purchases (e.g., standard PCs, basic microscopes, simple spectrometers) are excluded; use the appropriate product PSC instead of AN25.¹
• Pre-production development, low-rate initial production activities, and user demonstrations validating a system for specific use cases are excluded from R&D; code these outside Section A as applicable.¹

Frequently asked questions

• What distinguishes PSC AN25 from AN24?
  AN25 covers capital assets for health R&D—construction, major improvements, and major movable R&D equipment—while AN24 covers operating and administrative expenses (e.g., the costs of running research facilities and overhead).¹

• How should mixed office/lab construction be recorded under AN25?
  Report only the portion directly tied to conducting R&D. The PSC Manual allows calculating the R&D share as a percentage of total square footage for mixed-use buildings.¹

• Are there dollar thresholds that indicate use of AN25 for equipment?
  The PSC Manual highlights programs of $1 million or more devoted to the purchase or construction of R&D major equipment; minor equipment is excluded and should be coded with product PSCs.¹

• Which NAICS codes correspond to AN25?
  Not specified by official sources.¹

• When are AN25 obligations considered R&D in FPDS/SAM?
  Obligations for R&D facilities and major equipment are treated as a stage of R&D (stage 5) within the PSC structure and are entered accordingly in FPDS/SAM reporting.¹
