PSC J044

Overview

The Product Service Code (PSC) system is a standardized taxonomy used across U.S. federal procurement to classify goods and services for contracting, reporting, and spend analysis. PSC entries appear in FPDS/SAM contract records and are published and managed through the Product and Service Code Manual on Acquisition.GOV, which provides definitions, update procedures, and downloadable code files for agency reference.¹

PSC J044 covers maintenance, repair, overhaul, rebuild, commissioning, restart, and adjustment services for boilers, furnaces, steam-plant equipment, industrial drying equipment, and related nuclear-reactor equipment. Agencies use PSC J044 to classify service contract line items or task orders whose predominant work matches that descriptor as shown in the official PSC listing.²

Related NAICS and PSC codes

Not specified by official sources.¹

Agencies commonly select one or more NAICS codes at the solicitation or award level that best represent the primary industry performing the work; the PSC itself is a service classification and does not mandate a single NAICS assignment. Not specified by official sources.¹

Notes on classification and updates

• The Product and Service Code Manual (PSC Manual) publishes the PSC listings, user guidance, monthly/periodic code files, and the standard operating procedures for change requests and updates.¹
• Agencies determine appropriate NAICS designations during acquisition planning and solicitation drafting based on the predominance of the work. Not specified by official sources.¹

Frequently asked questions

• Q: What exact work must a solicitation include to use PSC J044?
  A: Use PSC J044 when the solicitation’s statement of work procures maintenance, repair, rebuild, commissioning, restart, or adjustment services specifically for boilers, furnaces, steam-plant systems, industrial drying equipment, or equipment tied to nuclear-reactor operations, consistent with the official PSC descriptor.²

• Q: Where are PSC definitions, code files, and change procedures published?
  A: The authoritative PSC Manual and associated files are published on Acquisition.GOV, which hosts the PSC listing, the SOP for code changes, and downloadable spreadsheets of current codes and descriptors.¹

• Q: Which NAICS codes apply to awards classified under PSC J044?
  A: The PSC Manual does not mandate a single NAICS mapping for PSC J044; contracting activities select NAICS codes based on the primary industry or predominance of the work for each acquisition. Not specified by official sources.¹

• Q: How can an agency request a PSC change or a new PSC assignment?
  A: Change requests follow the PSC Manual’s SOP: agencies submit a business case and supporting materials as described in the manual; the PSC governing authority reviews submissions and publishes approved updates in the periodic PSC files on Acquisition.GOV.¹
