PSC H977

Overview

The Product Service Code (PSC) framework standardizes how the U.S. federal government classifies goods and services in contracting to support FPDS/SAM reporting, spend analysis, and procurement tracking. The PSC Manual on Acquisition.GOV is the authoritative maintenance vehicle agencies use to assign and publish PSCs and related guidance for classification and reporting. ¹

PSC H977 is titled Other Quality Control, Testing, and Inspection — Musical Instruments, Phonographs, and Home‑Type Radios and identifies procurements for quality‑control, testing, and inspection services associated with those product categories. Use of H977 signals that the primary contract effort is inspection, testing, or acceptance of complete end items in the listed product areas. ²

Contracting notes

• PSC H977 is a service‑oriented classification and should be used when the primary effort on the contract line item is quality control, testing, or inspection for the listed product categories; work that is maintenance, installation, or technical representation should use the corresponding product or service PSCs. ²
• Obligations recorded in FPDS should reflect the PSC that best describes the principal service performed for accurate reporting and analysis; follow the PSC Manual guidance when assigning codes in FPDS and solicitations. ¹

Frequently asked questions

• What types of actions are properly reported under PSC H977?

  • H977 is appropriate when the contract’s principal effort is quality control, testing, or inspection of musical instruments, phonographs, or home‑type radios—end‑item QC and acceptance testing rather than repair, overhaul, or installation. ²

• How does a contracting officer choose H977 versus a maintenance PSC?

  • If the core requirement is inspection or conformance testing of end items, select H977. If the primary work is maintenance, repair, rebuild, installation, or long‑term technical representation, select the PSC that matches those services. Follow PSC assignment guidance in the manual. ²

• Are parts or accessories covered by H977?

  • Parts, accessories, and manufacturing of end items are normally classified under product PSCs such as 7720 for musical instrument parts rather than H977, which focuses on QC/testing/inspection of complete items. ³

• Does the PSC assignment affect small‑business rules or NAICS selection?

  • The PSC identifies the product/service class for reporting; NAICS codes and small‑business size standards are selected separately per solicitation and procurement rules. Not specified by official sources ¹
