PSC 2950

Overview

The Product Service Code (PSC) system standardizes how the U.S. federal government classifies what is being bought so contract actions can be tracked, analyzed, and reported consistently across FPDS and SAM.gov. The PSC Manual maintained on Acquisition.gov provides the authoritative definitions, maintenance process, and use guidance for each PSC class. ²

PSC 2950 — Turbosupercharger and Components — covers all turbosuperchargers and their components not otherwise classifiable. The PSC Manual cites examples such as engine turbosuperchargers and turbosupercharger regulators, and specifies that engine‑integrated superchargers are excluded and instead belong to Federal Supply Group 28 (Engines, Turbines, and Components). ¹

What this PSC covers

• Engine turbosuperchargers intended for use with internal‑combustion powerplants, when not otherwise classifiable. ¹
• Turbosupercharger regulators and similar control units associated with turbocharging assemblies. ¹
• Standalone turbosupercharger units supplied as replacement parts or spares. ¹
• Subassemblies and components of turbosuperchargers that do not fit more specific classes. ¹
• Turbocharging hardware packaged with related mounting or connection items, provided the predominant item is the turbosupercharger or its components. ¹
• Turbosupercharger items regardless of platform (e.g., aircraft, vehicular, marine, stationary) when not directed to a more specific PSC. ¹

Frequently asked questions

• What does PSC 2950 specifically include?
  The PSC Manual specifies that 2950 includes all turbosuperchargers and their components not otherwise classifiable, explicitly naming engine turbosuperchargers and turbosupercharger regulators. This capture includes complete units as well as components and subassemblies when no more specific PSC applies. ¹

• Are integrated superchargers coded under PSC 2950?
  No. Engine‑integrated superchargers are excluded from 2950. These items are placed in Federal Supply Group 28, which covers engines, turbines, and components, per the PSC Manual’s exclusion note. ¹

• Which PSC applies to repair services for turbosuperchargers?
  Use service PSC J029 for maintenance, repair, and rebuilding of equipment—engine accessories. Product codes like 2950 identify supplies and parts; service codes such as J029 identify the nature of the work performed on those items. ¹

• Which PSC applies to installation or leasing of turbosuperchargers?
  Installation of engine accessories falls under N029 (Installation of Equipment—Engine Accessories). Leasing or rental of engine accessories uses W029 (Lease or Rental of Equipment—Engine Accessories). These service PSCs complement the supply classification in 2950. ¹
