PSC M1AB

Overview

The Product Service Code (PSC) system standardizes how the U.S. federal government classifies goods and services for procurement, supporting FPDS reporting, spend analysis, and acquisition category management. The PSC Manual on Acquisition.gov is the authoritative registry and governance source for PSC assignments and updates. ¹

PSC M1AB is listed in the PSC Manual as "Operation of Conference Space and Facilities" and is used to record actions whose primary purpose is the operation (ongoing management and use) of conference and meeting spaces for federal procurements reported in FPDS. The PSC Manual provides the code label and placement within Category M (Operation of Structures/Facilities) but does not supply a detailed scope-of-work list for M1AB. Not specified by official sources. ¹

Related NAICS and PSC codes

No official PSC-to-NAICS crosswalk entries or explicit related-code mapping for M1AB are provided in the PSC Manual; agencies typically select the NAICS code appropriate to the predominant industrial classification of the services acquired per FAR guidance on NAICS selection. Not specified by official sources. ¹

Note: lease or rental actions are generally placed in the X1 series (e.g., X1) rather than M1 operation codes; agencies should not assume leases map to operation PSCs. ¹

How this PSC appears in federal reporting

Agencies report PSC values in FPDS under data element 8A, "Product or Service Code"; the FPDS data dictionary instructs selection of the code that best identifies the product or service procured and to report the code representing the majority of contract value. PSC entries are therefore the primary FPDS mechanism to indicate that an award principally procures facility-operation services, per the PSC Manual and FPDS guidance. ³

Frequently asked questions

• Q: What does the label "Operation of Conference Space and Facilities" actually mean for coding a contract?
  A: The PSC Manual assigns M1AB the label used to represent contracts whose predominant purpose is operating conference/meeting spaces; the manual does not enumerate detailed tasks or exclusions, so contracting officers must select the code that best represents the majority of contract value. Not specified by official sources. ¹

• Q: Where is the PSC recorded in FPDS?
  A: The PSC is recorded in FPDS data element 8A ("Product or Service Code"); agencies must choose the PSC that best identifies the product or service procured, reporting the code that represents most of the contract value. ³

• Q: Should leasing or rental of conference space be coded as M1AB?
  A: No — lease or rental actions are categorized under the X1 (Lease/Rental of Structures and Facilities) series in the PSC Manual rather than M1 operation codes; therefore leasing is not typically reported as M1AB. ¹

• Q: How is the NAICS code chosen when a solicitation references M1AB?
  A: NAICS selection follows FAR guidance: agencies assign the NAICS code that best describes the industry-of-the-supplier or the predominant economic classification for the acquisition. The PSC Manual does not supply a required NAICS crosswalk for M1AB. ²
