PSC H949

Overview

The Product and Service Code (PSC) framework standardizes how the U.S. federal government classifies purchased products and services for contracting, reporting, and spend analysis across systems such as FPDS and SAM. The PSC Manual (Acquisition.gov) defines PSC descriptors, category groupings, and maintenance procedures used by contracting officers, data analysts, and program managers to ensure consistent reporting. PSC H949 is in Category H9 and is intended for contracts where the primary deliverable is quality-control, testing, inspection, or related services specifically tied to maintenance and repair shop equipment; it supports reporting, performance measurement, and spend analytics for shop-equipment QC activities.¹

• Functional and acceptance testing of shop test stands, jigs, and fixtures.¹
• Quality-control and diagnostic services for repair-shop equipment.¹
• Calibration and verification of shop tooling and measurement fixtures when performed as part of QC/testing services.¹
• Non-medical laboratory-type testing performed to validate repair-shop equipment performance.¹
• Documentation and reporting associated with shop-equipment QC and inspection services.¹

How FPDS reporting uses this code

FPDS requires a single predominant PSC (data element 8A) be reported for each contract action; when the primary deliverable is QC, testing, or inspection services for maintenance and repair shop equipment, the action is reported under PSC H949. FPDS guidance explains PSC selection logic, where PSC values appear in reporting, and how to record the predominant product or service for award-level data.²

Product-group context (Federal classification)

The PSC Manual groups H949 within the broader H9 category for “Other Quality Control, Testing, and Inspection,” and provides category-level notes and exclusions that affect interpretation (for example, distinctions between hand tools, specialized shop equipment, and basic test instruments). Consult the manual for group-level guidance and cross-references to related PSCs and product groups.¹

Frequently asked questions

• Q: When should a contracting action use PSC H949 instead of a J-category maintenance PSC?

  • A: Use PSC H949 when the contract’s primary purpose is quality control, testing, or inspection services for maintenance/repair-shop equipment. Use a J-category PSC (for example J049) when the primary deliverable is maintenance, repair, or rebuilding labor for equipment rather than QC or testing services.¹

• Q: Does H949 cover calibration of precision instruments used in a maintenance shop?

  • A: Calibration and verification that are part of QC/testing for maintenance-shop equipment typically fall under PSC H949 when the service is predominately QC/testing. Routine repair or rebuild of instrumentation is more appropriately reported under a J-category maintenance PSC.¹

• Q: Are there explicit “Includes/Excludes” entries for H949 in the PSC Manual?

  • A: The PSC Manual provides the H949 descriptor and H9-category notes but does not itemize every possible include/exclude for each subitem; contracting officers should apply the manual’s category guidance and related product-group notes to determine proper coding.¹

• Q: Where to find authoritative selection guidance and a search tool for PSCs?

  • A: The official PSC Manual on Acquisition.gov is the primary source for definitions and category guidance; FPDS help pages explain how PSCs appear in award reporting and data elements; the government PSC Tool provides a searchable interface to locate PSCs and descriptors.¹
