PSC H268

Overview

The Product Service Code (PSC) system is a governmentwide taxonomy that classifies products, services, and R&D purchased by the U.S. federal government. PSCs are required in FPDS/SAM reporting to indicate what was bought and to support spend analysis, category management, and acquisition reporting. The PSC Manual is the authoritative maintenance vehicle for the list of active codes and high‑level headings. ¹

PSC H268 (Equipment and Materials Testing — Chemicals and Chemical Products) is a Category H2 entry used when the predominant subject matter of the procurement is testing equipment, testing services, or related laboratory activity focused on chemicals or chemical products. Agencies apply H268 when the primary deliverable or service is chemical testing, instruments for chemical analysis, consumables for chemical assays, or calibration/performance testing of chemical test instruments. ¹

What this PSC covers

• Equipment testing for chemicals and chemical products. ¹

• Calibration, verification, and performance-testing of chemical test instruments. ¹

Specific includes/excludes or deeper item-level scope for H268 are not enumerated in the public PSC Manual. Not specified by official sources. ¹

Related NAICS and PSC codes

The PSC Manual does not publish a mandatory NAICS-to-PSC crosswalk for H268; agencies select NAICS codes based on the predominant business activity or principal good/service in each acquisition. Not specified by official sources. ¹

Contract reporting and common pairings

Real-world FPDS/agency award records show H268 paired with a range of NAICS codes depending on contract context. For example, award listings may show H268 used alongside NAICS 541690 (Other Scientific and Technical Consulting Services) when the procurement emphasizes technical/testing services rather than manufacture of equipment. ²

Frequently asked questions

• Q: Where is H268 defined officially?
  A: H268 is defined in the federal PSC Manual as “Equipment and Materials Testing — Chemicals and Chemical Products.” The PSC Manual is the authoritative source for active PSC codes and high‑level headings. ¹

• Q: Is there an official NAICS-to-PSC crosswalk for H268?
  A: There is no single governmentwide NAICS-to-PSC pairing published for H268 in the PSC Manual; agencies assign NAICS codes based on the predominant activity reported in FPDS. Not specified by official sources. ¹

• Q: Can H268 be used on task orders that are primarily services rather than goods?
  A: Yes. The PSC should reflect the predominant product or service procured; if the primary deliverable is chemical testing services or testing equipment, H268 is an appropriate PSC to report. ¹

• Q: Where can examples of H268 in use be found?
  A: Examples appear in agency award lists and FOIA/award publications; some agencies’ award pages include entries coded H268 that can be reviewed for real-world pairing and contract context. ²
