PSC 4440

Overview

The Product Service Code (PSC) system is a governmentwide taxonomy used to categorize supplies and services procured by U.S. federal agencies. PSCs appear in systems such as FPDS and SAM to standardize reporting, analysis, and management of spending; they are governed and updated through the PSC Manual maintained on Acquisition.gov. ¹

PSC 4440 identifies supply items titled “Driers, Dehydrators, and Anhydrators.” Agencies assign 4440 to purchases where the principal purpose is equipment that removes moisture from materials, media, or process streams; it is a supply classification and not a service code. For Department of Defense coordinated acquisition, 4440 is listed with Defense Logistics Agency Land and Maritime (DSCC) as the buying lead under PGI 208.7006. ²

• Dehydrators designed to reduce moisture content in gas or liquid media. ¹
• Anhydrators intended to eliminate water from substances or systems. ¹
• Standalone moisture-removal equipment procured as supplies (not services). ¹
• Items acquired under DoD’s coordinated acquisition portfolio led by DLA Land and Maritime (DSCC). ²

DoD coordinated acquisition assignment (buying lead)

• Buying lead/IMM context: Under DFARS Subpart 208.70 and PGI 208.7006, coordinated acquisition assigns certain Federal Supply Classes to lead organizations; for 4440, DLA Land and Maritime (DSCC) is identified as the responsible buying activity. ²
• DSCC identification: PGI footnotes define “DSCC” as DLA Land and Maritime and outline coordinated-acquisition responsibilities across classes. ³

Coding and reporting notes

• PSCs are required data elements for contract reporting and are used across FPDS and SAM to enable standardized spend analytics; the official PSC Manual supplies the code set and governance. ¹
• When the requirement is for services (e.g., installation or maintenance), agencies must select the appropriate service PSC rather than a supply code such as 4440; specific service-code boundaries for this equipment family are not detailed in the manual. ¹

Frequently asked questions

• What does PSC 4440 cover?

  • PSC 4440 is a supply classification titled “Driers, Dehydrators, and Anhydrators,” used when procuring equipment whose primary function is moisture removal. It is part of the official PSC taxonomy maintained on Acquisition.gov. ¹

• Who is the DoD buying lead for PSC 4440 items?

  • DoD’s PGI 208.7006 lists 4440 under the Defense Logistics Agency Land and Maritime (DSCC) for coordinated acquisition, indicating DLA’s lead buying role for these items. ²

• Are installation or maintenance services coded under PSC 4440?

  • No. PSC 4440 is a product (supply) code. Service work should be coded under the appropriate service PSC; the manual does not specify detailed service-code boundaries for this equipment family. ¹

• Where is the most current, official list of PSCs for coding 4440 procurements?

  • The authoritative PSC Manual and the current downloadable PSC spreadsheet are hosted on Acquisition.gov; agencies rely on these files for coding and updates. ¹

• What related PSCs are commonly adjacent to 4440 in industrial environments?

  • Adjacent supply families include 4450 (Industrial Fan and Blower Equipment), 4460 (Air Purification Equipment), and 4330 (Centrifugals, Separators, and Pressure and Vacuum Filters), per the coordinated-acquisition listings. ²
