PSC H945

Overview

The Product Service Code (PSC) system standardizes how the U.S. federal government classifies products and services in procurement reporting. PSCs appear in FPDS and SAM submissions to identify “what” the government bought; the PSC Manual on Acquisition.gov is the authoritative source for PSC definitions, descriptors, and coding guidance. ¹

PSC H945 is defined in the PSC Manual as “Other Quality Control, Testing, and Inspection—Plumbing, Heating, and Waste Disposal Equipment.” It is used when the primary purpose of a contract action is quality control, testing, or inspection services related to plumbing, heating, or waste-disposal equipment and systems, and agencies report that primary purpose in FPDS. ¹

Usage in FPDS reporting

Agencies should select the PSC that reflects the predominant product or service for the reported action; PSCs are entered as the Product or Service Code (FPDS data element 8A) while environmental attributes are reported in data element 8L. When the contract’s primary effort is quality control, testing, or inspection for plumbing/heating/waste-disposal equipment, use PSC H945 in FPDS. ²

Frequently asked questions

• What does PSC H945 represent?
  PSC H945 denotes “Other Quality Control, Testing, and Inspection—Plumbing, Heating, and Waste Disposal Equipment.” Use it for contract actions whose predominant purpose is QC, testing, or inspection of those equipment categories. ¹

• How does H945 differ from H145, H245, or H345?
  H145, H245, and H345 each name a primary activity (quality control, testing, inspection). H945 is an “Other” grouping for additional QC/testing/inspection activities within the same equipment group; agencies should select the PSC that best matches the predominant work. ¹

• Does H945 map to a single NAICS code?
  Not specified by official sources ¹ — PSC descriptors guide FPDS reporting, while NAICS selections are determined by the nature of the contractor’s work and the predominant industry classification.

• Where is H945 recorded in contract reporting?
  H945 is recorded in FPDS as the Product or Service Code (data element 8A) when the predominant contract action is QC/testing/inspection for plumbing, heating, or waste-disposal equipment; FPDS guidance explains data-element usage and reporting rules. ²

• Can H945 be used with environmental attribute reporting?
  Yes. Environmental attributes are reported in FPDS data element 8L independently of the PSC; agencies may populate 8L (for example, “environmentally preferable” or “energy efficient”) when applicable to the acquisition. ²
