PSC K077

Overview

The Product Service Code (PSC) system is the U.S. federal government’s standardized taxonomy for classifying goods and services procured through federal contracts. PSCs appear in contracting systems such as FPDS and SAM to enable consistent reporting, spend analysis, and category management; the PSC Manual (FPDS) is the authoritative guide for PSC assignment and usage.¹

The K077 PSC designates modification work applied to equipment in the musical-instrument, phonograph, and home-radio categories where modification activities — rather than initial manufacture — are the primary deliverable reported on a procurement action. Typical uses include retrofits, integration of new assemblies, and configuration changes that materially alter existing equipment performance or capability.²

What this PSC covers

• Modification of musical-instrument equipment, including retrofits that change acoustic or electronic characteristics.²
• Modification of phonograph equipment, including cartridge, arm, or playback-system upgrades.²
• Modification of home-radio equipment, including receiver or tuner retrofits and reconfigurations.²
• Integration or retrofitting of assemblies and subsystems for the above equipment types (for example, replacing modules or adding new electronic control units).²
• Related adjustment, calibration, or configuration efforts performed as part of a modification contract when those activities are integral to the modification deliverable.²

Acquisition and reporting notes

PSC codes must be selected for federal contract actions to ensure proper FPDS reporting and visibility in spend analytics; assign the PSC that best describes the primary product or service being procured, which for modification efforts is the modification PSC rather than a manufacturing PSC. The PSC Manual provides assignment rules and examples for reporting PSCs in FPDS.¹

Frequently asked questions

• Q: When should the K077 PSC be assigned on a contract?
  A: Assign K077 when the principal contract deliverable is the modification of existing musical-instrument, phonograph, or home-radio equipment rather than original manufacture or wholesale supply. See the PSC Manual for reporting guidance and examples.¹

• Q: Does K077 cover repairs and maintenance?
  A: The code focuses on modification; whether a task is modification versus repair/maintenance depends on the SOW and the primary purpose of the action. Classification examples and boundary guidance are available from PSC reference sources.²

• Q: Are there standard NAICS mappings for K077?
  A: The PSC Manual does not impose a universal, one-to-one NAICS mapping for every PSC; NAICS selection must reflect the primary industrial classification of the work and follow FPDS/NAICS guidance for the action.¹

• Q: How does reporting a modification PSC affect spend analysis?
  A: Using a dedicated modification PSC like K077 enables analysts to separate modification work from new production or services, improving category-level visibility in FPDS-derived reports and helping to drive more accurate trend analysis.¹
