PSC Y1PC

Overview

The Product Service Code (PSC) system standardizes how the U.S. federal government classifies goods and services it purchases, supporting FPDS/SAM reporting, spend analysis, and governmentwide procurement tracking. The PSC Manual (GSA) defines and maintains the official code list and short descriptors used for federal procurement reporting. PSC Y1PC is listed in the Manual as "Construction of Unimproved Real Property (Land)" and is intended for contract actions where the predominant deliverable is construction work on unimproved land; the Manual provides the descriptor but does not publish a detailed line‑by‑line scope for Y1PC ¹.

Related NAICS and PSC codes

The PSC Manual lists the PSC descriptor for Y1PC but does not publish a single, definitive NAICS crosswalk within the PDF listing; the Manual’s supplemental crosswalk spreadsheet contains category alignments agencies may use. For specific NAICS-to-PSC alignments, consult the Manual’s crosswalk spreadsheet and agency guidance ¹.

How agencies use this PSC in FPDS reporting

Agencies record the applicable PSC in FPDS data element 8A to indicate the primary product or service purchased; FPDS help documentation explains data element usage and reporting expectations for PSC values ².

The PSC Manual directs that when multiple products or services exist within a contract action, the PSC selected should represent the predominant purchase reported in FPDS (the primary deliverable) rather than minor incidental items ¹.

Frequently asked questions

• Q: What does PSC Y1PC mean?
  A: PSC Y1PC is labeled "Construction of Unimproved Real Property (Land)" in the PSC Manual and is used when the predominant contract work is construction on unimproved land; the Manual provides the descriptor but not a detailed scope. ¹

• Q: How should an agency choose Y1PC when a contract includes multiple tasks?
  A: Select the PSC that represents the primary, predominant deliverable recorded in FPDS. If land construction is the major work, record PSC Y1PC; FPDS data element guidance clarifies where PSC values are entered. ²

• Q: Is repair or alteration of land reported under a different PSC?
  A: Yes. Repair or alteration activities for unimproved real property are captured under PSC Z2PC per the PSC Manual’s service/repair categories; use the PSC that best represents the predominant action. ¹

• Q: Where can I find a NAICS-to-PSC crosswalk for Y1PC?
  A: The PSC Manual’s supplemental crosswalk spreadsheet maintains suggested alignments between PSCs and NAICS codes; the PDF listing does not publish a single definitive NAICS mapping for Y1PC, so consult the Manual’s crosswalk and agency guidance. ¹
