PSC Z1KZ

Overview

The Product Service Code (PSC) system is a standardized federal taxonomy used to classify products and services procured by the U.S. government. PSCs appear in FPDS and related acquisition systems to identify “what” was bought, support spend analysis, enable consistent reporting, and help agencies and industry find relevant opportunities and contracts. The Product and Service Code Manual, maintained on acquisition.gov, is the authoritative source for PSC definitions, code families, and change procedures; FPDS guidance explains how PSCs are recorded in FPDS fields. ¹

PSC Z1KZ is the PSC Manual entry titled “Maintenance of Other Conservation and Development Facilities,” listed under Category Z (Maintenance, Repair, Alteration of Structures/Facilities). Use of the code in FPDS should reflect the predominant service purchased under a procurement. ¹

Maintenance vs. repair: scope and selection

Federal reporting distinguishes maintenance/operation (Category Z1) from repair/alteration (Category Z2) and from construction (Category Y1). When reporting in FPDS, agencies should select the PSC that best represents the predominant service or work performed; FPDS instructions explain the use of element 8A for the product/service code and related reporting conventions. ²

Frequently asked questions

• Q: How should Z1KZ be applied in FPDS reporting?
  A: Use Z1KZ as the product/service code in FPDS element 8A when maintenance of conservation and development facilities constitutes the predominant contract value or effort; follow FPDS guidance for choosing the single code that best identifies the product or service procured. ²

• Q: Is repair or alteration of the same facilities reported under Z1KZ?
  A: No. Repair and alteration activities are reported under Category Z2 PSCs (for example, Z2KZ). The PSC Manual separates maintenance (Z1) from repair/alteration (Z2) to maintain consistent reporting. ¹

• Q: Which NAICS codes map to Z1KZ?
  A: Not specified by official sources. The PSC Manual does not provide a definitive, one-to-one NAICS-to-PSC crosswalk for every PSC; agencies typically identify NAICS codes via market research and solicitation scope when both PSC and NAICS must be reported. ¹

• Q: Where to find authoritative guidance on PSC definitions, selection, and changes?
  A: The Product and Service Code Manual on acquisition.gov is the primary reference for PSC definitions, code families, and change procedures; FPDS documentation explains operational reporting requirements for PSCs in FPDS fields. ¹
