PSC H349

Overview

The Product Service Code (PSC) framework is the federal government’s standardized taxonomy for classifying products and services in procurement records. PSCs are used in FPDS/SAM reporting to categorize purchases, support spend analysis, and guide acquisition planning. The PSC Manual on Acquisition.gov is the authoritative listing and includes code definitions, “includes/excludes” guidance, and family-grouping language used to interpret individual H‑group inspection codes. ¹

PSC H349 — Inspection‑Maintenance and Repair Shop Equipment — designates acquisitions of inspection, testing, and non‑medical laboratory services tied to maintenance and repair shop equipment readiness, safety, and performance. Agencies typically use H349 for third‑party equipment acceptance testing, periodic inspections, calibration/condition assessments, and documentation/reporting of shop‑equipment status. ¹

How agencies commonly use H349

Agencies typically assign PSC H349 when procuring third‑party inspection, testing, or non‑medical laboratory services that evaluate maintenance‑shop equipment condition, safety, or performance (for example, elevator/escalator shop inspections and weight‑handling equipment testing). Use in solicitations commonly appears alongside NAICS such as 238290 and 811310 in FPDS records. ²

Frequently asked questions

• Q: What is the defining scope of PSC H349?
  A: PSC H349 covers inspection, testing, and non‑medical laboratory services related to maintenance and repair shop equipment; the PSC Manual groups H349 with other inspection family codes and provides “includes” and “excludes” language to clarify scope. ¹

• Q: Which NAICS commonly appear with H349 in federal awards?
  A: Federal award records commonly pair H349 with NAICS such as 238290, 811310, and occasionally 561210 for facilities‑support IDVs that include inspection tasks. FPDS award listings illustrate typical pairings. ²

• Q: Is medical or clinical laboratory testing included under H349?
  A: Medical and clinical laboratory services are explicitly excluded from the H3xx inspection family; medical laboratory testing should be classified under medical/dental laboratory PSCs rather than H349. ¹

• Q: Where can I search solicitations or awards that use H349?
  A: Use advanced search filters in FPDS, USAspending, and SAM.gov with PSC = H349 to find solicitations and awards; FPDS portal searches for product_or_service_code H349 show agency usage and NAICS pairings. ²
