PSC W031

Overview

The Product Service Code (PSC) system is the governmentwide taxonomy used to classify goods and services acquired by federal agencies for reporting and procurement analysis in systems such as FPDS and SAM. The PSC Manual is the authoritative maintenance and governance document for PSC assignment, change control, and official labels on Acquisition.gov. ¹

PSC W031 is recorded in the PSC Manual with the label "Lease or Rental of Equipment‑ Bearings." The manual presents this label as the standard FPDS code to record contract actions where the predominant line item is bearing lease or rental; the manual does not provide an extended descriptive definition or itemized inclusions/exclusions beyond the code title. ²

FPDS reporting and selection guidance

FPDS requires entry of the PSC in data element 8A and agencies should select the PSC based on the predominant product or service being purchased for the contract action; when multiple products/services exist on a single award, coding should reflect the predominant acquisition. The PSC Manual provides the authoritative instruction that the PSC indicates “WHAT” was bought and that the predominant item determines the PSC selection. ³

Frequently asked questions

• Q: What exact goods or services does PSC W031 represent?
  A: The PSC Manual lists W031 as "Lease or Rental of Equipment‑ Bearings" as the official code label. The manual does not provide additional item-level inclusions or exclusions for the code. ²

• Q: How should an agency decide to apply W031 on a solicitation or award?
  A: Code the award using the PSC that most accurately reflects the predominant product or service. If bearing lease/rental is the primary line item on the action, W031 is the appropriate PSC per the PSC Manual’s FPDS guidance. ²

• Q: Does W031 map to specific NAICS codes for reporting or set‑asides?
  A: The PSC Manual does not publish a single prescriptive NAICS crosswalk within the code entry; crosswalks and category alignments are provided separately in PSC spreadsheets on Acquisition.gov. Agencies should consult those PSC resources for mapping guidance. ¹

• Q: Where is the official source of truth for updates to W031 or other PSCs?
  A: The PSC Manual on Acquisition.gov and its accompanying PSC spreadsheets (activation/end dates, labels, change control) are the official sources for PSC labels and updates. Use those pages for authoritative change history and downloads. ¹
