PSC H958

Overview

The Product Service Code (PSC) system standardizes how the U.S. federal government classifies products and services in procurements, enabling consistent FPDS/SAM reporting, spend analysis, and category management. The PSC Manual on Acquisition.gov is the authoritative source for PSC definitions, labels, and general usage guidance for contracting and reporting across civilian and defense acquisitions.¹

PSC code H958 — Other Quality Control, Testing, and Inspection—Communication, Detection, and Coherent Radiation Equipment — appears in the PSC Manual index as the descriptive title for this grouping of quality-control and inspection activities. The Manual provides the label and title but does not expand H958 into an itemized, line-by-line scope or an exhaustive list of included tasks and equipment; specific program or agency solicitations typically clarify scope at the requirements/CLIN level when needed.¹

Related NAICS and PSC codes

Authoritative, itemized crosswalks between H958 and specific NAICS codes are not published in the PSC Manual; related PSCs (for modification, technical representative, logistics, or equipment supply) may be referenced by agencies in solicitations but are not enumerated by the Manual as formal H958 mappings.¹

How PSC H958 is used in procurement reporting

• PSC assignment: Contracting officers select the PSC that best represents the predominant product or service being procured and record it in FPDS at the appropriate award or CLIN level; PGI and FPDS guidance direct how PSCs should be applied for reporting and administrative purposes.²
• Reporting and category management: PSCs feed government-wide spend analyses and category alignments used by OMB, GSA, and agency category teams; the PSC Manual groups related QC/testing PSCs to support consistent reporting, but it does not provide item-by-item examples for H958.¹

Frequently asked questions

• Q: What is the exact official definition of H958?
  A: The PSC Manual lists H958 as "Other Quality Control, Testing, and Inspection—Communication, Detection, and Coherent Radiation Equipment." The Manual provides the descriptive title but does not enumerate specific line items under H958.¹

• Q: Where must H958 be entered on a contract action?
  A: The selected PSC should be recorded in the FPDS product/service code field for the award or the CLIN that best represents the predominant work; PGI/DFARS guidance explains PSC entry practices and CLIN-level reporting requirements.²

• Q: Do official crosswalks map H958 to NAICS?
  A: The PSC Manual does not publish a definitive NAICS crosswalk for H958; agencies commonly identify NAICS on solicitations to reflect the nature of the required services, but a formal, itemized crosswalk for H958 is not provided in the Manual.¹
