PSC L023

Overview

The Product Service Code (PSC) system provides standardized two‑ to four‑character codes the U.S. federal government uses to classify products and services reported in FPDS to enable consistent tracking, analysis, and reporting of procurement. The PSC Manual is the authoritative source for PSC definitions and administration.¹

PSC L023 — Technical Representative: Ground Effect Vehicles, Motor Vehicles, Trailers, and Cycles is a Category L technical‑representative code used to indicate contract actions that primarily obtain technical‑representative services for ground‑effect vehicles, motor vehicles, trailers, and cycles. It appears in the PSC Manual listing of Category L technical representative codes and is used when the predominant service reported is technical‑representative support for those vehicle groups.¹

The PSC Manual does not provide a single definitive crosswalk that maps every individual L‑code to NAICS codes in the printed manual; a definitive NAICS mapping for PSC L023 is not specified by official sources.¹

Assigning technical representatives (optional)

Agencies that require technical representation may designate program personnel to perform non‑contract administration technical duties under agency procedures; designation, scope, and limitations are governed by agency policy and applicable acquisition regulation guidance. For Department of Defense contexts, DFARS guidance clarifies that technical representatives perform non‑CAS technical duties and are distinct from contracting officer’s representatives.²

FPDS reporting and data elements (optional)

PSC values are entered in FPDS data element 8A (“Product or Service Code”), and contracting offices should select the PSC that represents the predominant product or service for the action; the PSC Manual documents FPDS reporting guidance and category alignment resources used to determine the appropriate PSC.¹

Frequently asked questions

• What does the PSC L023 PSC indicate on an FPDS record?
  It indicates the predominant contract action purchased technical‑representative services related to ground‑effect vehicles, motor vehicles, trailers, and cycles; it is a Category L technical‑representative code listed in the PSC Manual.¹

• Who may be assigned as a technical representative for contracts coded PSC L023?
  Agencies assign qualified program or technical personnel per agency procedures. Technical representatives perform non‑contract‑administration technical duties and are functionally separate from a COR unless specifically authorized by the contracting officer or agency policy.²

  The PSC Manual is the authoritative listing and reporting guidance for PSC selection; FPDS help pages and agency acquisition offices provide additional FPDS coding assistance.¹
