PSC K019

Overview

The Product Service Code (PSC) system is a governmentwide, alphanumeric taxonomy that classifies what is procured on federal contracts and awards. PSCs are entered in contracting records (for example, FPDS) to enable consistent tracking, reporting, and analysis of government spending; the PSC Manual is the authoritative source and maintenance vehicle for these codes.¹

PSC K019 — MODIFICATION OF EQUIPMENT- SHIPS, SMALL CRAFT, PONTOONS, AND FLOATING DOCKS — identifies modification activities applied to waterborne platforms and associated floating structures. The code is used in contract reporting to indicate that the primary scope of a procurement or contract action is modification (change, retrofit, alteration, or conversion) of ships, small craft, pontoons, or floating docks.¹

What this PSC covers

• Ship modification activities (structural, systems, and habitability upgrades)
• Small craft modification and alteration
• Pontoon retrofit and conversion work
• Floating-dock alterations and capacity changes
• Integration of new marine systems and equipment as part of modification
• Modifications that change configuration, capability, or mission fit

How agencies typically report and use K019

Agencies select PSC K019 when the predominant contract effort is modification (not new construction or routine maintenance). PSC selection supports FPDS reporting and downstream analysis of spend and programmatic trends; contracting guidance instructs selection of the PSC that best represents the predominant work performed.²

Frequently asked questions

• Q: When is K019 used instead of a maintenance PSC (for example, J019)?
  A: K019 is used when the contract’s primary objective is modification or alteration that changes configuration, capability, or mission role. If the predominant effort is repair, rebuilding, or routine maintenance, a maintenance PSC such as J019 is typically appropriate.¹

• Q: Does K019 apply to installation of new equipment on a ship?
  A: If the primary effort is equipment installation rather than broader modification of the platform, agencies may use the installation PSC (N019); if installation is part of a larger modification scope, reporting under K019 is appropriate.¹

• Q: Which NAICS should appear with K019 procurements?
  A: NAICS selection depends on the specific work; common NAICS for ship and boat modification work include 336611 and 336612, subject to the solicitation’s scope and the contracting officer’s NAICS determination.³

• Q: Where is the PSC entry recorded in government award reporting?
  A: The Product or Service Code is a required FPDS data element; contracting officers choose the PSC that best represents the predominant supplies or services procured when completing FPDS reporting.² See also: G2X — PSC K019.
