PSC H922

Overview

The Product Service Code (PSC) system is a government-wide taxonomy used to classify what the federal government buys; PSCs are recorded in FPDS (data element 8A), published and maintained via the PSC Manual, and used for reporting, spend analysis, and category management. The PSC Manual defines PSCs and their application in FPDS reporting and contract data standards.¹

PSC H922 — Other Quality Control, Testing, and Inspection‑ Railway Equipment — is the service‑level code the PSC Manual assigns to “other” quality‑control, testing, and inspection services associated with railway equipment in Category H9. Agencies use PSCs to describe the predominant product or service procured in FPDS reporting.¹

What this PSC covers

• Quality‑control, testing, and inspection services for railway equipment (general classification).¹
• Non‑specific inspection or QC services not separately classified under other H9 railway PSCs.¹
• Contract labor and third‑party services performing acceptance testing of rolling stock components.¹
• Commercial testing and laboratory services when applied to railway equipment (where applicable).¹
• Other ancillary testing or inspection activities related to railway systems and assemblies.¹

Related NAICS and PSC codes

Official PSC documentation groups inspection/QC PSCs and lists related maintenance/inspection PSCs in the railway equipment group; the following PSCs appear in the same group in the PSC Manual.¹

Type	Code	Descriptor
PSC	H322	Inspection‑ Railway Equipment.
PSC	J022	Maintenance, Repair, and Rebuilding of Equipment‑ Railway Equipment.
PSC	K022	Modification of Equipment‑ Railway Equipment.

(Official PSC Manual lists these PSCs as the inspection/maintenance/modification grouping for railway equipment.)¹

How agencies classify and report H922

Agencies enter PSCs into FPDS (data element 8A); FPDS guidance explains where PSC data are recorded and how to search or report on PSC-coded actions.³

PSC selection guidance in the PSC Manual indicates agencies should select the PSC that represents the predominant product or service being procured; H922 is appropriate when the primary contract line item is an “other” QC/testing/inspection service tied to railway equipment and not covered by a more specific PSC.¹

Frequently asked questions

• What is the primary purpose of PSC H922?
  PSC H922 designates other quality‑control, testing, and inspection services for railway equipment where no more specific PSC applies; it is a service code recorded in FPDS to describe the predominant service purchased for a contract line item.¹

• How should an awarding office select H922 in FPDS?
  The contracting office should choose the PSC that reflects the predominant requirement for the contract line (FPDS data element 8A). If the predominant requirement is an “other” QC/test/inspection service for railway equipment and no specific PSC fits, select H922.¹

• Does H922 cover laboratory analytical testing for railway materials?
  The PSC Manual groups testing and inspection services broadly under H‑category codes but does not list granular inclusions/exclusions for every service; agencies should confirm whether laboratory testing is the primary service and, if so, whether a different PSC or product code better matches the requirement. Not specified by official sources.¹

• Are inspection PSCs distinct from “other” QC/test/inspect codes?
  Yes; the PSC Manual separates explicit “Inspection” codes (inspection series) from “Other Quality Control, Testing, and Inspection” (H9) codes. Selection depends on whether the contract line is classified as inspection or as an “other” QC/testing service.¹
