PSC N026

Overview

The Product Service Code (PSC) system is the governmentwide taxonomy that classifies what the federal government buys. PSCs are recorded in FPDS (data element 8A) and are published and maintained via the PSC Manual to enable consistent reporting, spend analysis, and category management across federal contracting activities. PSC entries are labels used for contract and requisition coding; many entries are concise labels rather than full task‑level definitions, and agencies rely on the Manual and alignment spreadsheets for crosswalks and coding practice. For contracting actions where installation is the primary deliverable, a PSC from Category N is typically assigned to represent that predominant activity. ¹

PSC N026 is listed in the PSC Manual as "Installation of Equipment‑ Tires and Tubes" and appears within Category N (Installation of Equipment). The Manual provides the code label but does not supply an extended includes/excludes narrative for this specific entry. ¹

Related NAICS and PSC codes

Official PSC→NAICS crosswalk entries for N026 are maintained in the PSC alignment spreadsheets referenced by the Manual; the code list entry itself does not publish a definitive NAICS mapping on the same page. Consult the PSC alignment spreadsheet or agency FPDS guidance for specific NAICS associations. ¹

Coding and reporting guidance

The PSC Manual directs that the PSC data element in FPDS (data element 8A) must reflect the predominant product or service purchased; when multiple products or services appear on a single award, agencies should code to the predominant item by dollar value or scope. Assign PSC N026 when installation of tires and tubes represents the primary work of the action. For FPDS reporting procedures and tool assistance, consult FPDS help resources. ²

Frequently asked questions

• Q: When should a contracting officer use PSC N026 on a requisition?
  A: Use PSC N026 when the predominant deliverable on the contract or action is installation of tires and tubes (that is, installation is the primary objective rather than supply‑only or separate maintenance). The Manual emphasizes coding to the predominant product or service (FPDS data element 8A). ¹

• Q: Is there an “Includes/Excludes” list defining N026 tasks (mounting, balancing, alignment)?
  A: The PSC Manual shows N026 as the installation‑of‑tires/tubes label but does not provide a detailed includes/excludes narrative for this specific code; specific task‑level inclusions therefore are not specified by official sources. ¹

• Q: Can a tire supply line item use a different PSC than installation work on the same order?
  A: Yes. When a contract includes discrete supply and installation elements, contracting records may use separate PSCs for those line items. The PSC recorded for the award (FPDS data element 8A) should reflect the predominant product or service for the overall action. For FPDS coding and reporting guidance, see FPDS help. ²

• Q: Are there standard NAICS codes typically associated with installation of tires and tubes?
  A: The PSC Manual does not publish a definitive NAICS crosswalk on every code list page; NAICS associations are maintained in the PSC alignment spreadsheets and agency FPDS guidance. Consult those alignment resources for specific mappings. ¹
