PSC J091

Overview

The Product Service Code (PSC) system standardizes four-digit codes used across U.S. federal procurement to classify products and services reported in FPDS, SAM, and related systems. PSCs enable consistent tracking, analysis, and reporting of government spending; the Product and Service Codes Manual and related agency guidance govern PSC selection and maintenance. ¹

The PSC code J091 identifies maintenance, repair, and rebuild activities associated with fuels, lubricants, oils, and waxes equipment (label: MAINT/REPAIR/REBUILD OF EQUIPMENT- FUELS, LUBRICANTS, OILS, AND WAXES). Agencies apply the code on contract actions where those services represent the predominant work; precise scope language is established in the PSC Manual and by individual solicitations. Not specified by official sources. ¹

Frequently asked questions

• Q: How is PSC J091 selected for a contract action?
  A: Contracting officers select the PSC that represents the predominant product or service in the contract or order; when maintenance/repair/rebuild work for fuels/lubricants equipment is predominant, J091 is applied. Selection rules and data‑element guidance are in the PSC Manual. ¹

• Q: Which NAICS should be paired with PSC J091?
  A: NAICS pairing depends on the work performed and the solicitation’s primary industry classification; contracting officers assign the principal NAICS per solicitation. The PSC Manual does not prescribe a single NAICS pairing for J091. Not specified by official sources. ¹

• Q: Where are official PSC definitions and selection rules published?
  A: The Product and Service Codes Manual on Acquisition.gov is the primary official source for PSC definitions and selection guidance; the PSC Tool provides a searchable interface for selecting codes. ¹

• Q: Do agencies publish examples of work covered by PSC J091?
  A: Agencies commonly use J091 in individual solicitations and award reports (for example, fuel‑farm repairs or pump rebuilds), but a universal, centralized list of examples is not provided in the PSC Manual. Not specified by official sources. ¹
