PSC H222

Overview

The Product Service Code (PSC) system is the federal government’s standardized taxonomy for classifying goods, services, and research procured through federal contracting. PSCs are recorded in FPDS and surfaced in SAM.gov and other IAE systems to enable consistent spend reporting, search, and analysis. The General Services Administration (GSA) maintains the Product and Service Code Manual as the authoritative code set and management guidance for agencies selecting PSCs on award actions.¹

The PSC Manual lists PSC H222 as “Equipment and Materials Testing- Railway Equipment,” placing the code within the H2 Equipment and Materials Testing category. The manual provides the code title but does not include a separate “Includes/Excludes” narrative or itemized use cases for H222; the lack of expanded guidance for this specific code is not specified beyond the manual’s listings.²

Related NAICS and PSC codes

The PSC Manual does not publish a single authoritative NAICS crosswalk specific to H222; the manual lists neighboring PSC entries and related inspection codes but does not supply an itemized NAICS mapping for this code. Not specified by official sources.²

Optional — Inspection vs. testing (clarification)

The PSC Manual separates “Equipment and Materials Testing” (category H2) from “Inspection” (category H3). For example, PSC H322 appears under inspection as “Inspection- Railway Equipment,” indicating inspection activities are coded separately from testing activities in the manual’s structure.²

Optional — Reporting and FPDS usage

The PSC entered in FPDS data element 8A identifies “what” was purchased for a contract action; agencies should select the PSC that best represents the predominant product or service of the award. FPDS guidance defines the PSC data element and its role in federal spending records and reporting.³

Frequently asked questions

• Q: When should H222 be used on a contract action?
  A: Use PSC H222 when the predominant deliverable is equipment or materials testing specifically related to railway equipment, per the code title; the manual does not provide itemized use cases beyond the title and listing.²

• Q: How does H222 differ from H322 (Inspection- Railway Equipment)?
  A: The manual groups testing under H2 and inspection under H3; H222 is a testing code while H322 is listed under inspection, reflecting the code-structure separation in the PSC Manual.²

• Q: Is there an official NAICS crosswalk for H222?
  A: The PSC Manual and its supporting materials provide category-level alignments but do not publish a single definitive NAICS crosswalk for H222 in the main text; agencies should consult procurement guidance and relevant NAICS entries when mapping work scope to NAICS codes.²
