PSC C1JB

Overview

The Product Service Code system classifies the goods and services the U.S. government buys so spending can be tracked, analyzed, and reported across federal systems such as FPDS and SAM. The PSC taxonomy is maintained via the Product and Service Code Manual on Acquisition.gov and is used by agencies to select the code that best represents the predominant item or service purchased. ¹

PSC C1JB is defined in the PSC Manual under Category C1 (Architect and Engineering – Construction) as “Architect and Engineering–Construction: Testing and Measurement Buildings.” Agencies select this code when the requirement is for architect‑engineer (A/E) construction‑related services tied to facilities whose primary function is testing and measurement. ²
