PSC L091

Overview

The Product Service Code (PSC) system is the federal government’s standardized classification for the products and services purchased by U.S. agencies. PSCs are used in award reporting and analysis across systems such as FPDS and USAspending, and the authoritative PSC Manual and downloadable PSC data files are published on Acquisition.gov.¹

PSC L091 — Technical Representative — Fuels, Lubricants, Oils, and Waxes — is the official PSC label applied to contracting actions that procure technical-representative services tied to those product groups. The code title appears in the PSC data file; specific programmatic scope, discrete tasks, and performance requirements are determined by the contracting office and the contract statement of work.²
