PSC H347

Overview

The Product Service Code (PSC) system is a governmentwide four-character taxonomy that classifies the specific products and services purchased by federal agencies. PSCs are recorded in the Federal Procurement Data System (FPDS) and support procurement reporting, analytics, and category-management activities. The PSC Manual documents code definitions, application rules, and management processes used by contracting and reporting offices.¹

The PSC H347 is the service-level code for “Inspection- Pipe, Tubing, Hose, and Fittings.” The PSC Manual places H347 in the Inspection group and states it “Includes: Commercial Testing and Laboratory Services” and “Excludes: Medical and Dental Laboratory Services,” indicating the code captures nonmedical inspection and testing services for piping and related assemblies.²

How agencies commonly apply H347

Agencies normally assign H347 when the predominant contract effort is inspection, testing, or certification of piping systems and associated fittings rather than installation, maintenance, or repair. The contracting officer selects the PSC that best represents the predominant good or service on the award, per FPDS and PSC Manual guidance.¹

Frequently asked questions

• Q: What exactly must a contract deliver to be coded H347?
  A: A contract coded H347 should predominantly purchase inspection services for pipe, tubing, hose, or fittings (for example, commercial testing, laboratory analysis, NDE, or visual/dimensional inspection). Excluded items such as medical laboratory testing are explicitly noted in the PSC Manual.²

• Q: Can H347 be used for installation, maintenance, or repairs?
  A: No — installation, maintenance, and repair efforts are generally coded to installation/maintenance PSCs (for example, N047 or J047). Use H347 only when inspection/testing is the predominant service delivered.²

• Q: Which FPDS field holds the PSC and how is “predominant” product or service determined?
  A: FPDS stores the PSC in data element 8A (“Product or Service Code”). The contracting officer selects the code that best represents the predominant product or service on the action according to FPDS reporting instructions and the PSC Manual.¹

• Q: Are there environmental or recovered-materials attributes tied to H347 reporting in FPDS?
  A: Environmental attributes (for example, recovered-materials reporting) are recorded in FPDS data element 8L when applicable. Many service acquisitions are labor‑based and environmental attributes may not apply; see the PSC Manual for reporting rules.²
