PSC R405

Overview

The Product Service Code (PSC) system standardizes how the U.S. federal government classifies goods and services in procurement records, enabling consistent reporting, tracking, and analysis across FPDS and related acquisition systems. The PSC Manual on Acquisition.gov is the authoritative source for PSC definitions, code maintenance, and change control. ¹

PSC code R405 (Support‑Professional: Operations Research/Quantitative Analysis) is listed in Category R4 (Support‑Professional) and is the government‑designated code to record acquisitions where operations research or quantitative‑analysis services are the predominant deliverable. The PSC Manual provides the code title in the service‑code listing but does not include extended “Includes/Excludes” language for R405. ¹

What this PSC covers

• Operations research services (analysis of complex systems, modeling to inform decisions). Not specified by official sources. ¹
• Quantitative analysis services (statistical and econometric analyses to support program evaluation). Not specified by official sources. ¹
• Mathematical and statistical modeling and estimation. Not specified by official sources. ¹
• Simulation, optimization, and decision‑support analyses. Not specified by official sources. ¹

Specific “Includes/Excludes” language for PSC R405 is not provided in the PSC Manual; agencies should assign the PSC that best identifies the predominant product or service procured. ¹

Related NAICS and PSC codes

The PSC Manual lists R405 under Category R4 but does not publish an official NAICS crosswalk or a detailed list of related PSCs for R405 within the same entry. Not specified by official sources. ¹

How R405 is reported in FPDS (optional)

FPDS collects PSCs in data element 8A (“Product or Service Code”); the instruction is to report the code that best identifies the product or service procured and, when multiple codes apply, to report the code representing the greatest contract value. This FPDS requirement governs how R405 should be used in federal transaction reporting. ²

Frequently asked questions

• What does PSC R405 represent?
  PSC R405 is the Product Service Code titled “Support‑Professional: Operations Research/Quantitative Analysis,” used to record acquisitions where operations research or quantitative‑analysis services are the predominant deliverable; the PSC Manual lists the code title but does not provide extended scope text beyond the listing. ¹

• How should agencies choose R405 versus other support PSCs?
  FPDS guidance requires selection of the code that best identifies the product or service procured and to report the code representing the largest share of contract value; use the predominant service to select the PSC. ²

• Is there an official NAICS mapping for R405?
  The PSC Manual provides service‑code listings but does not publish a definitive NAICS crosswalk for R405 within the entry; crosswalk resources are provided separately in PSC Manual materials. Not specified by official sources. ¹

• Can R405 be used on task orders under a broader contract that covers multiple service types?
  Yes—when a contract or order contains multiple products/services, the PSC entered should reflect the predominant product/service for that specific action, per FPDS and PSC Manual guidance. ²
