PSC 2825

Overview

The Product Service Code (PSC) is a governmentwide taxonomy used to classify what the federal government buys, supporting consistent reporting in FPDS and SAM, spend analysis, and category management. The PSC Manual provides the official definitions, scope notes, and usage guidance and is maintained by Acquisition.gov with periodic updates. ¹

PSC 2825 is the supply code for Steam Turbines and Components within Product Group 28 (Engines, Turbines, and Components). Official guidance states this class includes mercury vapor turbines and is used when the predominant deliverable is a steam turbine or its components; it excludes maintenance, repair, and rebuilding services, which are coded under J028. ³

What this PSC covers

• Complete steam turbines as end items. ³
• Steam‑turbine components procured as supply items. ³
• Mercury vapor turbines. ³
• Items properly classed in Product Group 28 when the predominant deliverable is a steam turbine or component. ³
• Not maintenance, repair, or rebuilding services; those actions are coded under J028. ³
• Not reciprocating steam engines (2820) or water turbines (2830); these have separate PSCs. ³

Type	Code	Descriptor
PSC	2820	Steam Engines, Reciprocating; and Components
PSC	2830	Water Turbines and Water Wheels; and Components

Scope boundaries and common misclassifications

• Use 2825 when furnishing a steam turbine or its components as supplies; do not use it for overhaul/repair actions (use J028). ³
• Do not use 2825 for reciprocating steam engines; those belong under 2820. ³
• Non‑steam prime movers are out of scope: water turbines under 2830; gas turbines and jet engines under 2835 or aircraft prime movers under 2840. ³

Frequently asked questions

• What exactly does PSC 2825 represent?

  • PSC 2825 is the supply classification for Steam Turbines and Components in Product Group 28. The PSC Manual specifies that this class includes mercury vapor turbines and applies when the predominant deliverable is a steam turbine or its components, not services. ³

• How is PSC 2825 different from PSC 2835 or PSC 2840?

  • PSC 2835 covers gas turbines and jet engines for non‑aircraft prime‑mover applications and aircraft non‑prime‑mover uses. PSC 2840 covers aircraft prime‑moving gas turbines/jet engines. PSC 2825 is limited to steam turbines and their components. ³

• Which PSC applies to turbine overhaul or repair work?

  • Use J028 for maintenance, repair, and rebuilding of engines, turbines, and components (including steam turbines). PSC 2825 should be used only when the deliverable is a supply item such as a complete steam turbine or a turbine component. ³

• Does the PSC Manual specify component lists or size/output thresholds for PSC 2825?

  • Not specified by official sources. The PSC Manual defines the class and scope but does not enumerate component lists or prescribe specific capacity/output thresholds for coding under 2825. ¹

• Where is a PSC like 2825 recorded in FPDS/SAM and why does it matter?

  • The PSC is captured in FPDS data element 8A to identify what was bought. Agencies rely on PSCs for reporting, tracking, and category management decisions, and the PSC Manual provides the governing guidance for selection and use. ²
