PSC H330

Overview

The Product Service Code (PSC) framework is the federal government’s standardized taxonomy for classifying purchased goods and services in procurement reporting. PSCs are entered in FPDS as the “Product or Service Code” data element and are maintained through the Product and Service Code Manual on acquisition.gov; agencies use the manual to ensure consistent tracking, analysis, and reporting of government purchases. The code H330 is listed in the PSC Manual as “Inspection‑Mechanical Power Transmission Equipment” and is described as an inspection/laboratory classification (including commercial testing and laboratory services) that explicitly excludes medical and dental laboratory services. ¹

What this PSC covers

• Inspection services for torque converters and speed changers. ¹
• Inspection of gears, pulleys, sprockets, and transmission chain. ¹
• Inspection of belting, drive belts, fan belts, and related accessories. ¹
• Inspection of miscellaneous power transmission parts (shafts, collars, gearshafts, ball joints). ¹
• Commercial testing and laboratory analysis tied to mechanical power‑transmission equipment. ¹

Classification notes

• PSC selection: The PSC Manual directs agencies to select the PSC representing the predominant product or service in the contract action (FPDS data element 8A); this guidance governs when H330 should be used for inspection/testing lines of effort. ¹
• Includes/Excludes: H330’s official "Includes" and "Excludes" statements limit the entry to commercial testing/laboratory services and explicitly exclude medical and dental laboratory services; for requirements outside those boundaries, another PSC should be considered. ¹

Frequently asked questions

• Q: What is the primary purpose of H330?
  A: H330 classifies inspection and related commercial testing/laboratory services specifically for mechanical power‑transmission equipment; medical and dental laboratory services are excluded by the manual’s wording. ¹

• Q: When should H330 be used versus a maintenance or modification PSC?
  A: Use H330 when the predominant work is inspection/testing (commercial lab or technical inspection). Maintenance, repair, rebuilding, or modification activities should use their sector PSCs (for example, J030 for maintenance/repair or K030 for modification). ¹

• Q: How does H330 appear in FPDS reporting?
  A: Agencies report PSCs in FPDS under data element 8A; selection should reflect the predominant product or service being purchased and follow FPDS reporting guidance for choosing the single PSC that best represents the acquisition’s primary purpose. ²

• Q: How do I decide between H330 and similar inspection PSCs like H331?
  A: Choose the PSC that most specifically describes the inspected item: use H331 for bearing‑specific inspections and H330 for broader mechanical power‑transmission inspection services. When in doubt, follow the manual’s includes/excludes and the predominant‑work rule. ¹
