PSC H299

Overview

The Product Service Code (PSC) system is a government-wide taxonomy used to classify products and services procured by the U.S. federal government. PSCs support consistent reporting in FPDS, improve spend analysis, and are maintained through the PSC Manual and associated PSC data files on Acquisition.gov. ¹

PSC H299 is listed in the PSC Manual as "Equipment and Materials Testing- Miscellaneous." The code functions as a service-category identifier for contracts and task orders that report testing or laboratory activities for equipment or materials not captured under more specific H2xx equipment-testing PSCs; selection of the PSC in FPDS should follow the PSC Manual guidance to reflect the predominant product or service. ¹

• Commercial testing and laboratory services not listed under other H2xx categories. ¹
• Standalone testing tasks for single items or small lots classified as miscellaneous. ¹
• Contract reporting for non-medical, non-dental laboratory analyses when no specific H2xx applies. ¹
• Short-term or recurring test/analysis services billed as a discrete service line. ¹

Coding guidance and FPDS reporting

Selection of a PSC for a procurement should reflect the predominant product or service being purchased; FPDS data element 8A (“Product or Service Code”) must be completed based on that principle. The PSC Manual provides the authoritative PSC entries, definitions, and change history for reporting and category alignment. ¹

For FPDS-specific searching and reporting guidance (including ezSearch and help topics on which actions require PSC reporting), consult FPDS help resources. ²

Frequently asked questions

• Q: When should PSC H299 be used instead of a more specific H2xx code?
  A: Use H299 when the testing service is for equipment or materials not covered by any more specific H2xx “Equipment and Materials Testing” PSC. Select the PSC that best reflects the predominant product or service reported in FPDS per the PSC Manual. ¹

• Q: Does H299 cover medical laboratory testing?
  A: The PSC Manual generally separates equipment/materials testing from medical and dental laboratory services; medical and dental laboratory activities are captured under health-specific PSCs rather than many H2/H3 entries. Specific exclusions are described in the Manual. ¹

• Q: Is there an official NAICS crosswalk for PSC H299?
  A: The PSC Manual and its supplemental spreadsheets provide PSC entries and related notes, but an explicit, single NAICS-to-PSC mapping for H299 is not specified; agencies should consult the PSC spreadsheets and FPDS guidance for alignment. ¹

• Q: How should FPDS entries treat multiple testing activities on one contract?
  A: FPDS requires the PSC (data element 8A) to represent the predominant product or service on the action; when multiple testing activities exist, code the action to reflect the dominant effort or dollar value as described in FPDS and the PSC Manual. ²
