PSC Z1EZ

Overview

The Product Service Code (PSC) system is the federal standard for classifying what the government buys; PSCs are used in procurement reporting systems (for example FPDS) and are maintained via the PSC Manual on Acquisition.gov to support tracking, analysis, and reporting of federal spending ¹.

The PSC Z1EZ appears in the PSC Manual under Category Z1 (Maintenance of Structures and Facilities) and is labeled "Maintenance of Other Industrial Buildings." The manual provides the code label and taxonomy placement but does not supply a task-level, itemized scope for this specific code; agencies and contracting officers select PSCs by predominant procurement purpose in practice ¹.

Reporting & FPDS practice

PSCs are entered in FPDS as the Product or Service Code data element (element 8A); contracting officers select the PSC that represents the predominant product or service on a contract action. The PSC Manual directs selection by predominant procurement purpose rather than by exhaustive task lists or implicit NAICS mapping ¹.

Frequently asked questions

• Q: How is Z1EZ chosen for a contract?
  A: Agencies choose the PSC that best represents the predominant product or service purchased; for services, PSCs are recorded in FPDS element 8A. The PSC Manual emphasizes predominant-purpose selection over listing every possible task ¹.

• Q: Does Z1EZ map to a specific NAICS code and size standard?
  A: The PSC Manual provides labels and categories but does not publish a single authoritative NAICS mapping or size standard for each PSC; NAICS and size determinations are normally set by the contracting activity in solicitations or SAM/FPDS entries ¹.

• Q: Is Z1EZ appropriate for repair work, routine maintenance, or both?
  A: Category Z1 covers maintenance of structures and facilities while Category Z2 covers repair/alteration; this taxonomy indicates maintenance and repair/alteration are treated as separate PSC families, and the contracting officer selects according to predominant purpose ¹.

• Q: Where can I find PSC usage and reporting data?
  A: PSC usage is reported in FPDS, which houses contract actions and PSC entries; FPDS records and reports are the primary place to review how agencies apply PSCs in practice ².
