PSC N043

Overview

The Product Service Code (PSC) framework is a government-wide classification used to describe the “what” of federal procurements reported in FPDS and related acquisition systems; PSCs support standardized tracking, spend analysis, and category management and are maintained through the PSC Manual published on Acquisition.gov.¹
PSC N043 — Installation of Equipment- Pumps and Compressors — is the service code applied when the predominant contract activity is installation of pump and compressor equipment groups. It functions as the installation/service counterpart for Group 43 (Pumps and Compressors) and is used to signal that on-site installation work (mounting, anchoring, connecting, and configuring equipment) is the primary procurement effort.¹

Contracting notes

• Selection for FPDS reporting: the Product or Service Code (PSC) data element should reflect the predominant supplies or services being procured; use N043 when installation of pumps and compressors represents the primary effort on the award.²
• Group alignment: N043 sits within Group 43 (Pumps and Compressors) in the PSC Manual; related product classes (for example, compressors, power pumps, and hand pumps) are listed under that group.¹

Frequently asked questions

• Q: When should a contracting officer use PSC N043 on an FPDS award?
  A: Use PSC N043 when the predominant work procured is installation of pump or compressor equipment; report the PSC that best represents the majority of dollars or the primary effort on the action.²

• Q: Does N043 cover electrical hookups, piping, and commissioning?
  A: The PSC Manual identifies N043 as installation of pumps and compressors; explicit inclusion of electrical connections, piping work, or commissioning is not detailed in the code text and therefore not specified by official sources.¹

• Q: How does N043 relate to J043, K043, L043, and W043?
  A: Those codes are service siblings within Group 43: J043 covers maintenance/repair, K043 covers modification, L043 covers technical representative services, and W043 covers lease/rental for the same equipment family; the PSC Manual lists these related codes together.¹
