PSC H938
Overview
The Product Service Code (PSC) system is the government-wide taxonomy used to classify products and services in federal procurements. PSC codes recorded in the Federal Procurement Data System (FPDS) indicate what was bought, support spending reports, and are maintained via the PSC Manual on Acquisition.gov. 1
The PSC H938, Other Quality Control, Testing, and Inspection—Construction, Mining, Excavating, and Highway Maintenance Equipment, is a Category H9 service code for non-routine quality control, testing, and inspection activities specific to Group 38 equipment. The PSC Manual lists H938 under Category H9 as the “Other” quality-control/testing/inspection entry for construction, mining, excavating, and highway maintenance equipment. 1
What this PSC covers
- Equipment quality-control services for earthmoving and excavating machines. 1
- Testing and non-medical laboratory services for construction and highway-maintenance equipment. 1
- Inspection services that do not fit into the dedicated “Inspection” PSC subgroup. 1
- Specialized acceptance testing and operational verification of mining and excavating systems. 1
- Vendor- or third-party performed evaluation of highway maintenance machinery performance. 1

How agencies typically apply H938
Agencies record H938 in FPDS when the predominant effort is non-routine quality-control, testing, or inspection services for Group 38 equipment and the activity is not captured by a more specific H‑series PSC such as H338. The PSC Manual directs selection of the PSC that best represents the predominant product or service purchased. 1
Frequently asked questions
-
Q: When should H938 be used instead of H338?
A: Use H338 for the dedicated “Inspection” services; use H938 for other quality-control or testing activities that do not fall under the standard inspection description. Agency selection should reflect the predominant service procured. 1 -
Q: Where is the PSC recorded in federal reporting systems?
A: The PSC is entered in FPDS under data element 8A (“Product or Service Code”). FPDS documentation and the PSC Manual describe code usage and reporting guidance. 3 -
Q: Is there a published NAICS mapping for H938?
A: Not specified by official sources. The PSC Manual provides usage guidance but does not publish a single mandatory NAICS crosswalk for H938. 1 -
Q: Can H938 be used for contractor-supplied testing labs?
A: Yes. Commercial testing and laboratory services used for equipment QC/testing are included across related H‑group PSC entries; selection depends on whether the work is predominantly QC/testing for Group 38 equipment and whether a more specific PSC applies. 1
