PSC M1EZ

Overview

The Product Service Code (PSC) is the U.S. Government’s standardized taxonomy for classifying goods and services in federal procurement records (FPDS, SAM and related systems). The PSC Manual on Acquisition.gov is the authoritative registry and maintenance vehicle for active codes and monthly updates; contracting officers and analysts should confirm active codes there. The PSC code M1EZ, titled "Operation of Other Industrial Buildings," is a Category M1 entry (Operation of Structures and Facilities) and functions as a high-level reporting label for awards that principally procure operations or management of non‑maintenance, non‑production industrial buildings. The Manual provides the canonical code text and family placement but does not enumerate task‑level statements of work or technical performance requirements for individual procurements. ¹

Reporting and data-tagging considerations

• Contracts and orders that principally procure facility-operation services should be reported with the applicable PSC in FPDS and SAM; agencies use PSCs to support reporting, portfolio analysis, and Service Contract Inventory obligations. ²
• The PSC Manual is the authoritative source for the active code list and periodic updates; contracting officers should validate PSC selection against the current Manual edition on Acquisition.gov. ¹

Frequently asked questions

• Q: How specific is the PSC label for contract drafting and solicitation?
  Answer: The PSC title is a high‑level classifier intended for reporting and tracking rather than defining line‑item technical requirements. Detailed performance requirements belong in the statement of work or performance work statement; the PSC alone does not define SOW content. ¹

• Q: When should agencies use M1EZ versus other M1 codes?
  Answer: Agencies should select the code whose title best matches the predominant facility type or service on the award. For maintenance, production, or warehouse operations choose M1EB, M1EC, or M1GZ as appropriate; confirm selection in the PSC Manual. ¹

• Q: Are NAICS crosswalks provided for PSCs such as M1EZ?
  Answer: The PSC Manual and associated files provide code lists and alignment tools, but NAICS-to-PSC mapping is not prescriptive for every PSC. Contracting personnel should consult the current PSC materials on Acquisition.gov for any recommended alignments. ¹

• Q: Does assignment of M1EZ trigger Service Contract Inventory reporting?
  Answer: Some M1-family PSCs are included in Service Contract Inventory reporting considerations; agencies must follow PGI/DFARS entry guidance and agency policy to determine reporting requirements for a given award. ²
