PSC K052

Overview

The Product Service Code (PSC) system is the government-wide taxonomy that classifies what is being purchased in federal procurements and is recorded in FPDS/SAM to enable consistent reporting, spend analysis, and category management. The PSC Manual maintained by GSA is the authoritative registry for PSC codes and their descriptors. ¹

PSC K052 appears in the PSC Manual as "Modification of Equipment- Measuring Tools" and is used to classify contract actions where the predominant work is modification of measuring tools and related equipment. The manual provides the code descriptor but does not expand a detailed scope beyond that title; Not specified by official sources. ¹

How this PSC is reported in FPDS

Agencies report the predominant product or service in FPDS data element 8A, “Product or Service Code.” For actions where modification of measuring tools is the primary scope, enter K052 as the PSC; related environmental or attribute fields (element 8L) are separate. Reporting rules and data-element definitions appear in FPDS guidance. ²

Frequently asked questions

• When is K052 the correct PSC to use?
  Use K052 when the dominant contract work is modification of measuring tools or related measurement equipment and that modification represents the primary spend on the action. The PSC Manual lists the descriptor but does not supply a detailed scope. ¹

• How does K052 differ from J052?
  J052 covers maintenance, repair, and rebuilding (routine repair or overhaul). K052 is intended for modifications or alterations that change function, configuration, or capability. Both are distinct manual entries. ¹

• How should K052 entries be searched in FPDS/ezSearch?
  Use FPDS ezSearch or the FPDS advanced fields to filter by Product or Service Code (element 8A) equal to K052; results show recorded contract actions and obligations reported under that PSC. FPDS help and the data dictionary explain ezSearch and reporting fields. ²

• Are NAICS size standards tied to K052 in the PSC Manual?
  The PSC Manual provides code descriptors but does not assign NAICS size standards; NAICS selection and associated size standards are determined during solicitation and award reporting and by agency practice. Not specified by official sources. ¹
