PSC Z1GZ

Overview

The Product Service Code (PSC) system is a federal classification maintained by GSA and used across procurement systems (FPDS, SAM) to identify the type of product or service acquired. PSCs enable consistent tracking, analysis, and reporting of government spending and provide standardized codes for reporting, market research, and contract analytics. The PSC Manual on Acquisition.gov governs PSC definitions, usage guidance, and data-element mappings used by federal agencies. ¹

PSC Z1GZ is the service-class entry in the PSC Manual titled "Maintenance of Other Warehouse Buildings." It is assigned when the predominant requirement is maintenance of warehouse buildings (routine, scheduled, or recurring facility upkeep rather than construction or major repair). The entry appears under Maintenance (Category Z1) in the PSC Manual and is used as FPDS data element 8A where applicable. ¹

Reporting and FPDS usage

PSC values are recorded in FPDS as data element 8A; when a contract includes multiple products or services, agencies should select the PSC that best represents the predominant purpose of the acquisition. The PSC Manual directs agencies to populate environmental and supplemental attributes (for example, sustainability or service-specific flags) in FPDS data element 8L where applicable. Use of Z1GZ is appropriate when ongoing maintenance of warehouse buildings is the principal requirement rather than construction, major alteration, or single-project repair. ¹

Frequently asked questions

• Q: What precise activities must be included to justify use of PSC Z1GZ?
  A: The PSC Manual provides the short title "Maintenance of Other Warehouse Buildings" and indicates use for maintenance-type work; it does not enumerate a detailed activity list. Agencies should select Z1GZ when maintenance of warehouse buildings is the predominant requirement and document rationale in the contract record. ¹

• Q: How does Z1GZ differ from Z2GZ?
  A: Z1GZ is categorized under Maintenance (Z1) for routine or recurring facility maintenance. Z2GZ falls under Repair or Alteration (Z2) and is used for repair or alteration projects that are corrective, non-routine, or project-based. Agencies should choose the code that best reflects the contract’s principal purpose. ¹

• Q: Where is the PSC recorded in federal reporting systems?
  A: The PSC is entered in FPDS as data element 8A ("Product or Service Code"). Environmental and other supplemental attributes associated with the procurement may be recorded in FPDS data element 8L as described in the PSC Manual. ¹

• Q: If a contractor performs maintenance plus minor repairs, which PSC applies?
  A: If maintenance is the predominant ongoing requirement, select Z1GZ; if the contract is primarily a repair/alteration project, select the appropriate Z2-series PSC. Agencies must assess the principal purpose and document their selection. ¹
