PSC H125

Overview

The Product Service Code (PSC) system is a government-wide taxonomy that labels the goods and services procured by the U.S. federal government. PSCs are recorded in FPDS/SAM contract actions to identify what was purchased and to enable consistent reporting, spend analysis, and category management. The PSC Manual is the authoritative registry and governance document for these codes and is the primary source for PSC descriptions and usage guidance.¹

The PSC entry H125 appears in the PSC Manual as "Quality Control- Vehicular Equipment Components." It is intended to tag quality-control activities that pertain to vehicular equipment components in FPDS reporting (data element 8A), but the manual does not enumerate a detailed task list or exclusive scope for the code.¹

What this PSC covers

• Quality-control services focused on vehicular equipment components, assemblies, and subassemblies.
• Inspection and acceptance activities related to component conformity and contract requirements.
• Sampling, documentation, and reporting of component quality findings.
• Verification activities intended to determine compliance with specifications and standards.
• Supplier or depot-level component audits, oversight, and quality assurance support.

Specific activities and inclusions for H125 are not enumerated in the PSC Manual. Not specified by official sources.¹

Related NAICS and PSC codes

The PSC Manual does not publish a mandatory, one-to-one NAICS-to-PSC crosswalk that binds every PSC to specific NAICS codes; authoritative NAICS-to-PSC alignments are maintained in separate crosswalk spreadsheets and reporting tools used by agencies and category managers. For any given requirement, agencies should select the NAICS and PSC that best represent the primary purpose of the procurement rather than relying on an automatic mapping in the PSC Manual.¹

Category context

H125 belongs to PSC category H (Quality Control, Testing, and Inspection), which groups many equipment-focused quality-control service codes. Adjacent H-codes cover testing, inspection, and related quality functions for vehicles, engines, tires, and associated components; agencies commonly differentiate among H125, H225, and similar codes based on whether the primary activity is quality control, equipment testing, or maintenance-related work.¹

Frequently asked questions

• Q: What is the official description of PSC H125?
  A: The PSC Manual lists H125 as "Quality Control- Vehicular Equipment Components." It is a reporting label used in FPDS to indicate quality-control services for vehicular components; the manual does not expand the label into a prescriptive scope of tasks or exclusions.¹

• Q: Where is H125 reported on federal contract records?
  A: Agencies report PSCs in FPDS under data element 8A (Product or Service Code). Use the PSC that most closely matches the contract’s predominant product or service; FPDS technical guidance explains the data element structure and reporting expectations for PSC fields.²

• Q: How do I choose between H125, H225, and J025?
  A: Choose H125 when the primary requirement is quality-control services for vehicular components. If the predominant requirement is equipment/materials testing, consider H225; if maintenance, repair, or rebuilding predominates, use J025. The PSC Manual provides labels but not prescriptive decision rules.¹

• Q: Are the specific tasks covered by H125 defined in the PSC Manual?
  A: No. The PSC Manual provides the label and category context for H125 but does not provide a comprehensive list of included or excluded tasks. Agencies often develop internal guidance or rely on crosswalk tools for more detailed mapping.¹
