PSC 1955

Overview

The Product Service Code system standardizes how the U.S. government classifies what it buys so spending can be tracked, analyzed, and reported consistently across procurement systems. PSCs are used on contract actions in the Federal Procurement Data System and are governed by the Product and Service Code Manual issued on Acquisition.gov. ¹
PSC 1955 identifies “Dredges” within Product Group 19 (Ships, Small Craft, Pontoons, and Floating Docks). The manual specifies that Group 19 covers complete vessels, and PSC 1955 includes dredges without hulls, ocean-going dredges, and floating dredges; parts and accessories for such vessels are generally classified in Group 20 (Ship and Marine Equipment). ¹

What this PSC covers

• Complete dredging vessels as end items, including those purchased with or without a hull. ¹
• Ocean-going dredges procured as finished platforms. ¹
• Floating dredges used for inland or coastal operations. ¹
• Dredges categorized under Group 19; parts, assemblies, and accessories for use on dredges are classified in Group 20, not under 1955. ¹
• Dredges are excluded from PSC 1925 (Special Service Vessels) and are coded under 1955. ¹

Lifecycle-related service PSCs often paired with dredge procurements

• Maintenance/repair of vessels such as dredges is coded under J019 (Maintenance, Repair, and Rebuilding of Equipment—Ships, Small Craft, Pontoons, and Floating Docks). ¹
• Installation of shipboard equipment on dredges may use N019 (Installation of Equipment—Ships, Small Craft, Pontoons, and Floating Docks). ¹
• Leasing of dredges would be captured under W019 (Lease or Rental of Equipment—Ships, Small Craft, Pontoons, and Floating Docks). ¹

Frequently asked questions

• What exactly is covered by PSC 1955?
  PSC 1955 is a product code for dredges as complete vessels. The PSC Manual lists dredges without hulls, ocean-going dredges, and floating dredges under this class. Parts and accessories are typically classified in Group 20 (Ship and Marine Equipment). ¹

• Does PSC 1955 include dredging services?
  No. PSC 1955 is for end items (the vessel). Service acquisitions must be coded to the service PSC that best represents the work; the manual instructs selecting the PSC based on the predominant product or service being purchased. Specific dredging-service PSC mapping is not specified by official sources. ¹
  See also on G2X: PSC J019, N019, W019.

• How should dredge parts and shipboard accessories be coded?
  The Group 19 note states that only complete vessels (including dredges) belong in Group 19; end items, assemblies, parts, attachments, or accessories for use in or on such vessels are classified in Group 20 (Ship and Marine Equipment). ¹

• Are specific dredge types (e.g., cutter suction, hopper) enumerated under PSC 1955?
  Not specified by official sources; the manual provides an “Includes” list (dredges without hull, ocean-going dredges, floating dredges) but does not enumerate technical subtypes. ¹

• What PSC should be used for leasing or maintaining dredges?
  Leasing falls under W019; maintenance, repair, or rebuilding uses J019. For equipment installation aboard a dredge, use N019. These are service PSCs aligned to ships and small craft. ¹
