PSC H155

Overview

The Product Service Code (PSC) system standardizes how the U.S. federal government classifies products and services in procurement records, enabling consistent identification, reporting, and analysis across systems such as FPDS and SAM. The PSC Manual and its published current listing (spreadsheet) are the maintained authoritative sources that contracting officers and acquisition professionals use to select and report PSCs for solicitations, awards, and historical reporting. ²

The PSC H155 — Quality Control- Lumber, Millwork, Plywood, and Veneer — is the PSC Manual descriptor applied to procurements that identify quality-control, testing, or inspection activities tied to lumber, millwork, plywood, and veneer items or assemblies. This descriptor is used for reporting and acquisition-classification purposes in federal procurement records. ¹

What this PSC covers

• Quality-control and inspection services for lumber materials and structural timber.
• Evaluation and testing of millwork items such as doors, trim, and mouldings.
• Inspection and grading of plywood panels and sheet goods.
• Veneer inspection and surface/finish assessment.
• Dimensional verification, tolerance checks, and moisture-content testing.
• Documentation, certification, and conformance reporting tied to material acceptance. ¹

Related NAICS and PSC codes

• Omitted — official crosswalks mapping H155 to specific NAICS or other PSCs are not presented as a single authoritative mapping entry within the public PSC Manual; therefore, related-code mapping is not listed here. Not specified by official sources. ¹

Procurement contexts and notes

• Typical solicitation contexts: standalone quality-control task orders, inspection services bundled in construction or supply contracts, and third-party material acceptance testing where traceable documentation is required. This list is illustrative, not exhaustive, and the PSC Manual provides the official descriptor for reporting. ¹
• Labeling and reporting: Agencies enter PSCs (including H155) in procurement reporting fields (for example Block 7b on agency forms and FPDS entries) following PSC Manual guidance and agency FAR/PGI direction on reporting. ³

Frequently asked questions

• Q: What exactly does PSC H155 represent?
  A: PSC H155 is the PSC Manual entry for quality-control, testing, and inspection services specifically for lumber, millwork, plywood, and veneer. The Manual provides the official descriptor used in federal procurement reporting. ¹

• Q: Where should H155 appear in procurement documentation?
  A: Use H155 in the PSC field of solicitations, awards, and FPDS reporting when the primary scope is QC/inspection of lumber-related products; contracting officers follow PSC Manual and agency reporting guidance to determine the primary PSC. ³

• Q: Does H155 map to one or more NAICS codes?
  A: The PSC Manual lists PSC descriptors but does not publish a single definitive NAICS-to-PSC crosswalk inside the manual text for every PSC; NAICS selection is context-dependent and typically determined by the contracting activity based on the primary work. Not specified by official sources. ¹

• Q: Are inspections versus other quality-control roles covered by different PSCs for wood products?
  A: Yes. The PSC Manual uses distinct PSC groupings for inspection, quality control, technical representative, and similar service types; related PSCs such as H355 or L055 carry their own descriptors and are selected based on the specific role and scope. ¹
