PSC N091

Overview

The Product Service Code (PSC) system standardizes how the U.S. federal government classifies products and services in procurement records. PSCs are applied to FPDS and SAM transactions to tag solicitations and awards, enabling consistent spend analysis, category management, and reporting across agencies. The PSC Manual on Acquisition.gov is the authoritative source for PSC codes, descriptors, and the change process; practitioners should consult it for code definitions and assignment guidance ¹.

The PSC N091 (INSTALLATION OF EQUIPMENT‑ FUELS, LUBRICANTS, OILS, AND WAXES) is used when the primary requirement is installation services for systems or equipment that handle, dispense, store, or process fuels, lubricants, oils, or waxes. Typical installation activities include site preparation, tank and piping installation, mechanical mounting, interconnection, and commissioning of fuel‑handling or lubricant distribution equipment ¹.

What this PSC covers

• Fuel storage and transfer system installation, including tanks and associated piping.
• Fuel and lubricant dispensing equipment installation (pumps, hose reels, nozzles).
• Installation of metering, filtration, and monitoring units integral to fuel/lubricant systems.
• Installation of oil, grease, and wax processing or dispensing systems.
• Integration and connection of equipment to existing site utilities when part of the installation scope.
• Site preparation and civil work specifically required for installation of fuels/lubricants equipment ¹.

Common contract uses

• Military or civilian base fuel‑farm installation contracts for tanks, pumps, piping, and metering equipment where installation is the primary deliverable; apply PSC N091 for installation line items in FPDS/SAM ¹.
• Embassy and overseas facility projects that add or replace fuel handling systems and record installation activities as separate procurement line items; installation work is represented by PSC N091 when the service, not the product, is the main procurement outcome ¹.
• Multi‑line solicitations combining supply and installation typically separate the equipment supply (appropriate supply PSC) from installation tasks coded to PSC N091 to preserve reporting accuracy ¹.

Contracting considerations

• PSC selection: contracting officers should assign PSCs per the PSC Manual; correct use of N091 depends on whether the statement of work identifies installation as the primary requirement. Not specified by official sources ¹.
• Line-item structure: when requirements include both equipment supply and installation, separate line items and use the corresponding PSCs to avoid conflating product spend with installation services. Not specified by official sources ¹.
• Reporting and analysis: accurate PSC assignment improves the utility of FPDS spend queries and category analytics for procurement planning and market research ¹.

Frequently asked questions

• Q: When should a requirement use PSC N091 instead of a supply PSC?
  A: Use N091 when the procurement’s primary deliverable is installation (site work, mounting, piping, commissioning). If the procurement is primarily the sale of tanks, pumps, or other equipment with incidental delivery, record those under the appropriate supply PSC ¹.

• Q: Does N091 cover routine maintenance?
  A: Routine maintenance and repair are generally assigned to maintenance/repair PSCs such as J091. Use N091 for initial installation work rather than recurring sustainment activities ¹.

• Q: Are there prescribed NAICS codes tied to N091?
  A: The PSC Manual lists PSCs and descriptors but does not mandate a single NAICS for every PSC; NAICS selection should reflect the primary industrial classification of the work (construction, specialty trade, or manufacturing) and be chosen accordingly. Not specified by official sources ¹.

• Q: How does PSC assignment affect FPDS reporting and category management?
  A: The PSC on each FPDS line item drives category tagging for spend analysis, market research, and strategic sourcing; correct PSC use (for example, N091 for installation) improves visibility of installation‑type expenditures across agencies ¹.
