PSC H353

Overview

The Product Service Code (PSC) system standardizes how the U.S. federal government classifies products and services for procurement reporting and analysis in systems such as FPDS and SAM. PSCs enable consistent tracking, spend analysis, and category management across agencies and are maintained through the PSC Manual and associated government guidance.¹

PSC H353 — Inspection- Hardware and Abrasives is listed in the PSC Manual as an inspection/service code that “Includes: Commercial Testing and Laboratory Services” and “Excludes: Medical and Dental Laboratory Services.” This designation indicates H353 is intended for non‑medical inspection and commercial laboratory/testing activities related to hardware and abrasive items; the manual does not provide detailed item-level examples in the narrative text.²

Procurement and reporting notes

• FPDS coding: PSCs are entered in FPDS data element 8A; selection should reflect the predominant product or service on the contract or order. Use FPDS guidance and agency policy to determine the appropriate PSC for reporting.³
• Environmental/attribute reporting: Environmental attributes are reported in FPDS data element 8L when applicable; selecting H353 does not by itself indicate any environmental attributes or qualifiers in FPDS.³

Frequently asked questions

• What specific services are captured by PSC H353?

  • The PSC Manual identifies H353 as “Inspection- Hardware and Abrasives,” noting inclusion of commercial testing and laboratory services and exclusion of medical/dental laboratory services. The manual’s narrative does not supply item-level examples.²

• How should H353 be used when a contract contains multiple products or services?

  • FPDS guidance directs selection of the PSC that represents the predominant product or service purchased on the contract or order (data element 8A). If inspection/testing of hardware and abrasives is the primary deliverable, report H353 as the PSC.³

• Are medical or dental testing services included under H353?

  • No. The PSC Manual explicitly excludes medical and dental laboratory services from H353; those activities are reported under medical-specific PSCs and associated guidance.²

• Which NAICS codes map to H353?

  • Not specified by official sources.² The PSC Manual provides PSC categories and crosswalk spreadsheets, but it does not publish a single authoritative NAICS narrative mapping for H353.

• Where should H353 work be reported in FPDS if the contract is mostly labor (inspection personnel)?

  • Report the PSC that reflects the predominant acquisition output. Labor-centric inspection contracts whose primary deliverable is inspection or testing should be reported with the corresponding inspection PSC (for example, H353), consistent with FPDS data element guidance.³
