PSC W091

Overview

The Product Service Code (PSC) system is the governmentwide taxonomy used to classify what the federal government purchases. PSCs are recorded in procurement reporting systems such as FPDS and SAM to enable standardized tracking, spend analysis, and category management; the PSC Manual and associated tools govern PSC assignment and maintenance.¹

Per official PSC guidance and selection tools, PSC W091 is the four‑character code used to indicate lease or rental transactions of products within the Fuels, Lubricants, Oils, and Waxes supply group. Detailed inclusions, exclusions, and examples for W091 are designated across the Product and Service Codes Manual and selection tools; an authoritative, line‑by‑line public definition for this specific code is not provided on a single .gov page. Not specified by official sources.²

Contracting considerations

• Reporting: Use W091 on orders where the predominant contract value is a lease or rental (not a supply purchase); FPDS reporting must be consistent with the PSC Manual and agency coding rules.¹
• Pricing and terms: Rental arrangements frequently require clear statements of ownership, fuel accountability, environmental compliance, and returns/turn‑in conditions; the PSC does not replace FAR or agency contracting‑clause requirements. Not specified by official sources.²
• Crosswalking: Agencies align PSCs to spend categories for category management; ensure the PSC reflects the primary acquisition attribute to avoid misalignment and to support accurate governmentwide spend analysis.²

Frequently asked questions

• What distinguishes PSC W091 from a straight supply purchase code?

  • W091 denotes lease or rental actions (temporary possession/use) rather than title transfer. If the contract principally purchases fuel product inventory (permanent transfer of title), a supplies PSC is typically used for reporting and category mapping.¹

• Where is the official list of active PSCs and code titles?

  • The Product and Service Codes Manual on Acquisition.gov and the PSC selection tool provide the authoritative list of active PSCs and their titles; agencies should reference those resources when coding awards.²

• Can W091 be used for long‑term commercial fuel contracts?

  • If the procurement is structured as a lease or rental (periodic payments for temporary use), W091 can apply. If structured as a purchase with title transfer, use a product PSC such as 9140 for fuel oils.²

• How does PSC choice affect spend category alignment?

  • PSC selection determines category mapping used in governmentwide spend analysis; coding a lease as W091 aligns spend to leasing or fuel rental categories and will affect category management reporting and dashboards.²
