PSC H229

Overview

The Product Service Code (PSC) system is a standardized classification used across U.S. federal procurement to label goods and services in FPDS and related reporting systems. PSC values support consistent tracking, reporting, obligations analysis, and spend analytics; the official list and descriptors are maintained in the PSC Manual on Acquisition.gov and are the authoritative source for PSC reporting conventions and descriptors.¹

PSC H229 is listed in the PSC Manual as "Equipment and Materials Testing- Engine Accessories." It designates testing and materials-evaluation activities tied to engine accessory items in federal procurements, used by contracting officers and data reporters to classify awards. The Manual provides the official descriptor but does not enumerate specific accessory part types or exhaustive item lists; contracting officers interpret scope relative to solicitation and statement-of-work requirements.²

How agencies record PSCs in procurement systems

Agencies populate the Product or Service Code field (FPDS Block 7b) when reporting contract actions; the PSC Manual supplies the code list and descriptors that populate that field and describes policy for PSC use. PSC values feed downstream reporting in FPDS/USASpending and support award categorization and analytics.³
