PSC 2940

Overview

The Product and Service Codes (PSC) system classifies the products and services the U.S. federal government buys, supporting consistent reporting and analysis in systems such as FPDS and SAM. PSCs are governed and updated through the PSC Manual maintained on Acquisition.gov, which provides definitions, inclusions, exclusions, and coding guidance for contracting professionals. ¹

PSC 2940 is defined as Engine Air and Oil Filters, Strainers, and Cleaners, Nonaircraft. It covers filtration and cleaning components designed specifically for engines other than aircraft or guided missile prime movers. Items not designed for engines belong under other classes (e.g., Air and Oil Filters under 4310 or 4330, Strainers under 4730); aircraft or guided‑missile prime mover filtration is classified under 2945. ²

Coding guidance

The PSC Manual directs reporting the “predominant” product or service purchased for each action in FPDS. For mixed buys, select the PSC that best represents the principal item; use 2940 only when engine‑specific filtration/cleaning components are the primary items and are not for aircraft prime movers. ¹

DoD supply management assignment

Within DoD, Federal Supply Class 2940 is assigned to the Defense Supply Center Columbus (DSCC), indicating DLA Land and Maritime manages supply support for this class. This assignment aligns 2940 with other nonaircraft engine accessory classes (e.g., 2910, 2920, 2930). ³

Frequently asked questions

• What exactly does PSC 2940 include?
  PSC 2940 includes engine air and oil filters, strainers, and cleaners designed for engines other than aircraft or guided‑missile prime movers. It explicitly excludes general‑purpose filters and strainers not designed for engines and aircraft prime‑mover items. ²

• When should PSC 2940 be used instead of PSC 2945?
  Use 2940 for engine filtration on nonaircraft engines; use 2945 when the items are specifically designed for aircraft or guided‑missile prime movers. The aircraft versus nonaircraft distinction in Group 29 is explicit in the PSC Manual. ²

• Which organization manages DoD supply for PSC 2940?
  The Defense Logistics Agency’s DSCC (DLA Land and Maritime) is assigned to FSC 2940 under DFARS PGI Part 208’s DLA assignments listing. ³

• How does PSC 2940 relate to NAICS on a solicitation?
  PSCs classify what the government is buying, while NAICS codes classify the industry of the supplier for size standards. The contracting activity designates the NAICS code in the solicitation under FAR 52.204‑8; PSC 2940 may appear alongside the applicable NAICS. ⁴

• Are environmental attributes reported for buys coded under PSC 2940?
  Yes. Environmental attributes (e.g., energy efficient, biobased, recovered content) are reported in FPDS data element 8L when applicable, consistent with PSC Manual guidance. ¹
