PSC K047

Overview

The Product Service Code (PSC) system is the standardized taxonomy the U.S. federal government uses to classify products and services in procurement records. PSCs enable consistent reporting in systems such as FPDS and SAM and are maintained and published through the Product and Service Code Manual on Acquisition.gov.¹

PSC K047 is listed in the PSC Manual as "Modification of Equipment- Pipe, Tubing, Hose, and Fittings." The code classifies contract line items and actions where the primary work is modification or alteration of pipe, tubing, hose, and related fittings as reflected in federal procurement reporting.¹

Reporting and FPDS usage

FPDS requires reporting the single PSC that best identifies the product or service procured; when the primary work is modification of pipe/tubing/hose/fittings, the PSC Manual indicates classification under K047. FPDS data element rules direct selection of the PSC that represents the majority of contract value for the line item.²

Frequently asked questions

• Q: What exactly does PSC K047 identify on a contract?
  A: PSC K047 identifies contract line items where the principal effort is modification or alteration of pipe, tubing, hose, and fittings. Contracting officers should select the PSC that best represents the primary work as defined in the PSC Manual.¹

• Q: When should agencies use K047 instead of J047 or N047?
  A: Use K047 when the primary effort is modification/retrofit of piping components. Use J047 for maintenance/repair/rebuilding and N047 for installation actions; the PSC Manual groups these by activity type.¹

• Q: Is selection of K047 mandatory in federal reporting systems?
  A: Selection of a valid PSC is mandatory for FPDS entries; the chosen PSC must best identify the product/service procured. FPDS data rules require a PSC on awards and the PFDS/FPDS guidance governs that requirement.²

• Q: Are there official NAICS crosswalks for K047?
  A: The PSC Manual requires both PSC and NAICS fields on awards, but it does not provide a single authoritative NAICS-to-PSC crosswalk; agencies use procurement context to select the appropriate NAICS. Not specified by official sources.¹
