PSC 3915

Overview

The Product Service Code system is a governmentwide taxonomy that classifies what agencies buy so contract actions in FPDS and SAM can be tracked, analyzed, and reported consistently. PSC structure and updates are maintained through the PSC Manual on Acquisition.gov, which agencies use when coding awards. ¹

Within Group 39 (Materials Handling Equipment), PSC 3915 covers materials feeders and parts feeders used to control the rate of delivery of bulk materials, packages, or objects—typically synchronized with companion machinery to feed specific amounts from bins or hoppers to process or mixing equipment. It includes dry materials feeders and parts feeders, and excludes conveyor feeders (classify under PSC 3910) and certain other specialized feeders. ²

What this PSC covers

• Volumetric feeding devices that control delivery rate of bulk materials to process or mixing machinery. ²
• Feeders synchronized with companion equipment to deliver accurate, continuous amounts from storage bins or hoppers. ²
• Dry materials feeders used in industrial processes. ²
• Parts feeders that orient and feed discrete items into production operations. ²
• Materials handling feeders used as conveying devices where the rate of delivery is controlled. ²
• Feeder units interchangeable between machines for process integration. ²

Scope notes, inclusions, and exclusions

• Notes: Class 3915 is restricted to materials feeders and parts feeders that serve as conveying devices where delivery rate can be controlled. ²
• Includes: Dry materials feeders; parts feeders. ²
• Excludes: Conveyor feeders (apron, belt, chain, flight, pan, etc.), which are classifiable under PSC 3910; aggregate and fines feeders; water‑purification dry chemical feeders. ²

Coding guidance from the PSC Manual

• In FPDS, the PSC is recorded in data element 8A, and should reflect the predominant item bought on the action (e.g., choose 3915 when feeders are the primary product). ³
• Environmental attributes (e.g., energy efficient/biobased) are reported separately in FPDS data element 8L and apply based on contract requirements. ³

Frequently asked questions

• What is PSC 3915?
  PSC 3915 designates materials and parts feeders that meter delivery of bulk materials or items, typically feeding predetermined amounts from hoppers to processing equipment; it includes dry materials feeders and parts feeders. ²

• How is PSC 3915 different from PSC 3910?
  PSC 3915 excludes conveyor feeders (apron, belt, chain, flight, pan, etc.). Those are coded under PSC 3910 for conveyors. Use 3915 when the device’s defining function is controlled‑rate feeding, not general conveying. ²

• Are installation or maintenance services covered by PSC 3915?
  3915 is a product class within Group 39. Services (e.g., installation, maintenance) are coded under appropriate service PSCs; the Manual instructs choosing the PSC based on the predominant product or service for each action. ³

• Are there environmental reporting fields tied to PSC 3915 buys?
  Yes. FPDS data element 8L captures environmental attributes (e.g., energy efficient, biobased) when applicable to the acquisition; agencies select these in addition to coding PSC 3915 in element 8A. ³

• Where is the official definition and the latest updates for PSC 3915?
  The current PSC Manual (April 2025 edition) on Acquisition.gov provides Group 39 definitions, including PSC 3915 notes, inclusions, and exclusions, and lists changes across versions. ²
