PSC N079

Overview

The Product Service Code (PSC) system is a government-wide taxonomy used to classify purchased products and services across U.S. federal contracting for reporting, analysis, and procurement management. Agencies populate FPDS/SAM contract records with PSCs; the PSC Manual on acquisition.gov maintains the code list and short descriptors. ¹

PSC N079 is listed in the PSC Manual as "Installation of Equipment- Cleaning Equipment and Supplies" and is applied when the primary requirement is installation of cleaning-related equipment and associated supplies. The PSC Manual provides the short descriptor but does not enumerate specific included or excluded items. ¹

What this PSC covers

• Installation of cleaning equipment and supplies (site placement, mounting, anchoring).
• Integration of equipment with facility utilities (electrical, plumbing, controls).
• Commissioning, basic operational checks, and handover to the contracting activity.
• Coordination with vendor technical representatives and manufacturer field service.

Specific inclusions, exclusions, and item-level examples are not listed in the PSC Manual. Not specified by official sources. ¹

Common contract uses and reporting

Agencies typically record installation-focused procurements under PSC N079 when the predominant deliverable is equipment installation rather than supply-only or labor-only services. The PSC Manual provides the short code descriptors used for FPDS reporting. ¹

FPDS guidance directs selection of the PSC that reflects the predominant product or service of the action; when the primary purpose is maintenance/repair, an adjacent code such as J079 should be considered instead. ²

Frequently asked questions

• Q: When should a requirement be coded as PSC N079?
  A: Use PSC N079 when the contract’s primary deliverable is the installation of cleaning equipment or related supplies and installation is the predominant purpose reported in FPDS. Choose the PSC that best matches the action’s primary product/service. ¹

• Q: Does N079 cover consumable cleaning supplies (chemicals, wipes)?
  A: The PSC Manual provides only the short descriptor and does not list item-level inclusions or exclusions; whether consumables are coded separately depends on the acquisition’s predominant deliverable. Not specified by official sources. ¹

• Q: Is installation plus ongoing maintenance reported under N079?
  A: If installation is the predominant work and maintenance is incidental, N079 may apply. If maintenance/repair is the primary ongoing deliverable, an adjacent PSC such as J079 should be used to reflect the award’s primary purpose. ²

• Q: Are leasing or rental actions coded to N079?
  A: No. Lease or rental of cleaning equipment is categorized under W079; the PSC Manual separates installation, rental, and maintenance codes. ¹

Related NAICS and PSC codes

Relevant NAICS codes for PSC N079 typically describe contractors and firms that perform equipment installation, specialty trade services, or machinery service; select the NAICS that best matches the contractor’s primary industry for the requirement. For PSC definitions and family groupings, see the PSC Manual. [1]

NAICS	238210	Electrical Contractors and Other Wiring Installation Contractors	Relevant when installation requires electrical wiring, power connections, or electrical system integration. [3]
NAICS	238220	Plumbing, Heating, and Air‑Conditioning Contractors	Use when the installation requires plumbing, piping, or HVAC connections for cleaning equipment (e.g., drains, water supply, condensate). [4]
NAICS	238990	All Other Specialty Trade Contractors	Applicable for specialized on‑site installation work that does not fit standard trade categories. [5]
NAICS	811310	Commercial and Industrial Machinery and Equipment (except Automotive and Electronic) Repair and Maintenance	Use when the contractor’s primary business is machinery/equipment service and the action includes post‑installation commissioning or service agreements. [6]
PSC	J079	Maintenance/Repair/Rebuild of Equipment - Cleaning Equipment and Supplies	Use instead of N079 when the predominant requirement is maintenance or repair. [1]
PSC	K079	Modification of Equipment - Cleaning Equipment and Supplies	Use when the primary deliverable is equipment modification rather than initial installation. [1]
PSC	L079	Technical Representative - Cleaning Equipment and Supplies	Use for on‑site technical representative or manufacturer field‑service contracts. [1]
PSC	W079	Lease or Rental of Equipment - Cleaning Equipment and Supplies	Use for leasing/rental actions; leasing is distinct from installation services. [1]

Choose the NAICS that best reflects the principal industry of the performing contractor; FPDS guidance also directs users to select the PSC and NAICS that each best represent the primary purpose of the award. [2]
