PSC M1NZ

Overview

The Product Service Code (PSC) system provides a governmentwide taxonomy that classifies the products and services acquired by federal agencies for consistent reporting, analysis, and spend-tracking in FPDS/SAM; the PSC list and guidance are maintained through the PSC Manual on Acquisition.gov. PSC M1NZ is titled "Operation of Other Utilities" in the PSC Manual and is used to report contracting actions where the predominant service purchased is the operation of utilities not separately enumerated under other M1 codes. The PSC Manual lists M1NZ within Category M1 (Operation of Structures and Facilities) but provides no extended inclusions or exclusions beyond the title; additional scope details are not specified by official sources. ¹

What this PSC covers

• Miscellaneous utility operations not classified under other M1 utility PSCs. ¹
• Operation of utility-related systems or services that do not fit the M1NA–M1NE categories. ¹
• Non-building utility functions (for example, site-level or system-level utility operations). Not specified by official sources. ¹
• Third-party vendor operation of utility assets where contract reporting identifies the operation as the predominant service. ¹
• Utility coordination or management when not otherwise described by a more specific PSC. Not specified by official sources. ¹

FPDS reporting guidance

FPDS reporting practice requires selecting the PSC that represents the predominant product or service purchased for the contract action; when a services contract is predominantly labor-based, select the PSC that best describes the primary service outcome. Use the PSC Manual and FPDS help resources to confirm appropriate element 8A (PSC) selection for each Contract Action Report. ¹

Common adjacent PSCs (lease, construction, maintenance)

The PSC Manual groups construction, lease/rental, and maintenance counterparts for utility work under the X-, Y-, and Z-series (for example, X1NZ Lease/Rental of Other Utilities, Y1NZ Construction of Other Utilities, and Z1NZ Maintenance of Other Utilities). These counterpart codes support consistent reporting across lifecycle activities. ¹

Frequently asked questions

• Q: What is the primary purpose of PSC M1NZ?
  A: PSC M1NZ identifies contracting actions where the predominant service is the operation of utilities not otherwise specified in nearby M1 codes; the Manual provides only the title and basic placement in Category M1. ¹

• Q: How should agencies choose between M1NZ and a more specific M1 code?
  A: Agencies should select the PSC representing the predominant product or service in the award; if the operation clearly fits a specific M1 utility PSC (for example, water supply or sewage), use that specific code instead of M1NZ. ¹

• Q: Does PSC M1NZ replace NAICS classification?
  A: No. PSCs describe what was bought for FPDS reporting, while NAICS classifies the industry of the performing entity; they are separate data elements used together in federal reporting and analysis. See NAICS guidance for industry classification details. ²

• Q: Where can I find reported contract actions coded to M1NZ?
  A: FPDS (FPDS‑NG) is the authoritative location for searching reported contract actions by PSC; use the FPDS public search and help files to locate awards coded to this PSC. ³
