PSC K023

Overview

The Product Service Code (PSC) system is a four-character taxonomy the U.S. federal government uses to classify goods and services procured through contracting actions. PSCs enable standardized reporting in FPDS, support spend and category analyses, and are maintained and published in the Product and Service Code Manual on Acquisition.gov. The PSC code K023 is listed in the Manual as "Modification of Equipment- Ground Effect Vehicles, Motor Vehicles, Trailers, and Cycles." Agencies report contract actions under K023 when the predominant effort is modification, alteration, conversion, retrofit, upfit, or other reconfiguration that changes a vehicle’s form, fit, or function. ¹

Contract reporting & FPDS usage

PSC entries are recorded in FPDS as data element 8A and should reflect the predominant product or service procured on the reported contract action. FPDS guidance and the PSC Manual together govern selection of the appropriate PSC code for an award record; contracting officers should follow FPDS instructions when entering PSCs. ²

Frequently asked questions

• Q: When is K023 appropriate to use on a contract?

  • A: Use K023 when the predominant contract effort is modification (alteration, conversion, retrofit, or upfit) of ground-effect vehicles, motor vehicles, trailers, or cycles. The PSC Manual defines the code and examples for application. ¹

• Q: How does K023 differ from J023?

  • A: J023 covers maintenance, repair, and rebuilding of the same vehicle groups, while K023 specifically covers modifications that change configuration or capabilities rather than routine repair. See the Manual for definitions. ¹

• Q: Which NAICS codes should be paired with K023 on a solicitation?

  • A: The PSC Manual does not prescribe a single NAICS pairing for K023; NAICS selection depends on the industry activity that best represents the principal purpose of the modification work. Not specified by official sources. ¹

• Q: Where will contracting data showing awards coded to K023 be found?

  • A: Award records that use K023 appear in FPDS; ezSearch and standard FPDS reports can be queried for actions by PSC. Use FPDS search tools to filter by PSC. ³
