PSC Y1JB

Overview

The Product Service Code (PSC) system is a governmentwide taxonomy used to classify what the U.S. federal government procures. PSCs are entered in FPDS/SAM to identify the primary product or service purchased, support spend analysis, enable category management, and improve reporting consistency across agencies. The PSC Manual is the authoritative source for PSC codes, titles, and placement; supplemental spreadsheets referenced by the manual provide mappings and change history for Governmentwide category alignment.²

PSC Y1JB appears in the PSC Manual within Category Y1 (Construction of Structures and Facilities) with the short descriptor “Construction of Testing and Measurement Buildings.” The manual provides the official label and placement for this code but does not include an extended includes/excludes narrative specific to Y1JB; agencies should rely on the PSC Manual and related guidance when assigning this code to contract actions.¹

Reporting & FPDS usage

When reporting contract actions in FPDS, the PSC is entered in data element 8A (“Product or Service Code”); environmental or socioeconomic attributes related to the acquisition are reported in other designated data elements (for example, 8L for environmental attributes). The PSC Manual instructs agencies to select the PSC that represents the predominant product or service procured for the contract action.¹

Frequently asked questions

• Q: What is the authoritative definition of PSC Y1JB?
  A: The authoritative source is the PSC Manual, which lists PSC Y1JB with the descriptor “Construction of Testing and Measurement Buildings.” The manual does not include an extended narrative for this specific code, so agencies interpret scope using the manual and related guidance.¹

• Q: Should testing equipment procurement be coded to Y1JB?
  A: No—if the contract primarily purchases testing or measurement equipment, that procurement is generally recorded with an appropriate product-oriented PSC or National Stock Number, not a construction PSC. Select the PSC representing the predominant buy for the contract action.¹

• Q: Is there a maintenance counterpart to Y1JB?
  A: Yes. PSC Z1JB is listed in the PSC Manual as the maintenance counterpart, “Maintenance of Testing and Measurement Buildings.” Use maintenance PSCs when the primary requirement is upkeep or repair rather than new construction.¹

• Q: Where are PSC-to-NAICS mappings for planning and market research?
  A: The PSC Manual references supplemental spreadsheets and change logs for Governmentwide category alignment, including PSC-to-NAICS crosswalks used for planning and market research; consult the PSC Manual page and its linked materials for the latest spreadsheets and guidance.²
