PSC Y1KB

Overview

The Product Service Code (PSC) framework is the U.S. federal government’s standardized taxonomy for classifying goods and services in procurement records (FPDS/SAM). PSCs enable consistent categorization for reporting, analysis, and spend visibility; the PSC list and maintenance procedures are published and maintained via the PSC Manual on Acquisition.gov.¹

PSC Y1KB — CONSTRUCTION OF CANALS — is the PSC assigned to procurement actions that procure canal-construction work. In federal award reporting Y1KB is commonly paired with NAICS 237990 (Other Heavy and Civil Engineering Construction) on contract actions reported to FPDS.²
