PSC H193

PSC H193 — Quality Control — Nonmetallic Fabricated Materials

Overview

The Product Service Code (PSC) system is a governmentwide, four-character taxonomy used to classify products and services acquired by federal agencies for procurement reporting, spend analysis, and category management. PSCs populate FPDS/SAM award records and are maintained through the PSC Manual and related Governmentwide tools to ensure consistent coding across acquisitions and enable enterprise-level category management and analytics.¹

The PSC entry H193 — Quality Control‑ Nonmetallic Fabricated Materials — is the government classification applied when the predominant contract activity is quality control, testing, or quality assurance work specifically related to fabricated nonmetallic materials (for example: plastics, rubber, glass, ceramics, composites). The official PSC listing provides the short title and category placement within the H‑series (quality control/testing) but does not define specific technical test methods or prescribe NAICS crosswalks for every use case.¹

What this PSC covers

• Quality‑control services for fabricated plastics and polymer products.
• Testing and acceptance inspection of composite panels and laminated materials.
• Nonmetallic product conformance verification to specification or contract requirements.
• Laboratory analysis related to nonmetallic material performance (mechanical, thermal, chemical).
• On‑site material inspection and sampling for nonmetallic fabricated components.
• Supplier quality surveillance and corrective‑action verification for nonmetallic suppliers. ¹

Common procurement contexts

• Contract lines for vendor‑provided materials acceptance where the government requires independent QC services for plastics, glass, ceramics, or composite parts; commonly applied in manufacturing support, depot maintenance, materiel qualification, and retrofit programs where independent verification is required by contract specification. ¹
• Use when inspection and testing of nonmetallic items is the principal purpose of the award; if the primary deliverable is supply or a different service, select the PSC that reflects the award’s predominant purpose. Not specified by official sources for threshold, bundling, or detailed crosswalk rules beyond FPDS coding guidance. ¹

Frequently asked questions

• Q: When should H193 be selected instead of an inspection PSC such as H393?
  A: Choose H193 when the contract’s primary deliverable is QC/testing services focused on nonmetallic fabricated materials (ongoing QA/QC programs, laboratory testing services). Use H393 when the principal activity is acceptance inspection or formal inspection reporting. ¹

• Q: Are NAICS crosswalks defined for H193 so small‑business size standards can be applied?
  A: The PSC Manual does not prescribe a single NAICS mapping for every PSC; NAICS is chosen based on the industry activity (manufacturing, testing laboratories, or services) and must be selected per FPDS/NAICS guidance and agency practice. Not specified by the PSC Manual. ¹

• Q: Does the PSC listing mandate test standards when H193 is used?
  A: No. The PSC entry identifies the activity type but does not mandate test methods. Applicable standards and methods are set in the contract statement of work, agency specifications, or referenced technical standards. ¹

• Q: What tools help select PSCs and avoid miscoding?
  A: Use the official PSC Manual for authoritative listings and the Product Service Code selection tool for assistance with common mappings and lookup; agencies should validate selections against FPDS coding rules and the acquisition’s statement of work. ²
