PSC 6670

Overview

The Product Service Code (PSC) is a governmentwide taxonomy the U.S. federal government uses to classify what is being acquired for reporting and analysis in procurement systems. PSCs are entered on contract actions to enable consistent tracking, spend analysis, and portfolio management; they are maintained through the official PSC Manual and used in FPDS reporting. ¹

PSC 6670 covers “Scales and Balances.” Per the PSC Manual, this class includes coin-operated, household, industrial, postal, and laboratory scales and balances. It is selected on awards and orders when those items are the predominant supply bought. ¹
