PSC H393

Overview

The Product Service Code (PSC) system standardizes classification of products and services procured by the U.S. federal government to support FPDS and SAM reporting, spend analysis, and acquisition planning. The PSC Manual on Acquisition.gov is the authoritative listing and maintenance vehicle for PSCs and is the primary reference for valid PSC codes and their included/excluded activities. ¹

PSC H393 — Inspection- Nonmetallic Fabricated Materials — is an H‑category inspection grouping in the PSC Manual defined to include commercial testing and laboratory services applied to nonmetallic fabricated materials and to exclude medical and dental laboratory services; the Manual is the governing reference for permitted uses and explicit exclusions of this PSC. ²

Related NAICS and PSC codes

The PSC Manual does not enumerate specific related NAICS codes for H393; agencies typically map PSC selections to the NAICS that best describe the supplier’s primary line of business, but those mappings are agency-specific and not listed in the Manual. Not specified by official sources. ¹

Scope and exclusions (official guidance)

The PSC Manual groups H393 under inspection/testing categories, explicitly noting inclusion of commercial testing and laboratory services and exclusion of medical and dental laboratory services; the Manual provides the definitive include/exclude text for this PSC. ²

How agencies register and report PSCs

FPDS/FPDS‑NG requires reporting a valid PSC from the PSC Manual on award entries; the Product/Service Code field must be populated with the code that best identifies the product or service procured and must be selected from the PSC Manual list. ³

Frequently asked questions

• What does PSC H393 specifically mean on an award record?
  PSC H393 — Inspection- Nonmetallic Fabricated Materials — is the PSC used to identify inspection or commercial testing services associated with nonmetallic fabricated materials; the Manual lists included commercial testing and excluded medical/dental laboratory services. ²

• Is H393 appropriate for polymer or composite testing?
  The Manual groups inspection of nonmetallic fabricated materials under H393 and lists commercial testing as included; the Manual does not enumerate material subcategories (polymers, composites), so agency judgment and procurement context determine appropriateness. ²

• How should H393 be selected for FPDS reporting?
  Select the PSC that best represents the predominant product or service on the award and choose a valid code from the PSC Manual when populating the Product/Service Code field in FPDS/FPDS‑NG. ³

• Does H393 cover medical-device polymer testing?
  Medical and dental laboratory services are explicitly excluded from H393 in the PSC Manual; medical-device testing that qualifies as medical/dental laboratory work should be coded to the appropriate medical PSC, not H393. ²
