PSC R425: Support - Professional: Engineering and Technical — Active Federal SAM.gov Contracts & NAICS Crosswalk

Federal procurement intelligence, spending breakdown, NAICS/NIGP crosswalk, and contract capture guide for PSC R425 (Support - Professional: Engineering and Technical).

Product and Service Code (PSC) R425 — Support - Professional: Engineering and Technical — is an official federal procurement classification within Portfolio R — Professional, Administrative & Management Support managed by the General Services Administration (GSA) under the Federal Procurement Data System (FPDS) Product and Service Codes Manual. Across federal agencies, contracting officers obligate approximately $34.2 Billion annually under PSC R425, with 1,120+ Bids active solicitations, pre-solicitation notices, and task order RFQs circulating on SAM.gov and agency e-Buy portals. While a 6-digit NAICS code defines a contractor's overall industry and Small Business Administration (SBA) size standard, PSC R425 specifies the exact service (engineering) deliverable being purchased on the contract line item (CLIN). In federal solicitation architecture, PSC R425 is most frequently paired with Primary NAICS 541330 (Engineering Services), which carries an SBA small business size standard of $25.5 Million ($47M Military/Aero). Major buying commands—led by Department of Defense (Army, Navy, Air Force, Space Force) (68% of spend), NASA (12%), and Department of Transportation (FAA) (8%)—use PSC R425 to categorize statements of work encompassing Systems Engineering and Technical Assistance (SETA) for Defense & Aerospace Programs; Weapons System Test & Evaluation (T&E), Reliability, Maintainability & Logistics; and Mechanical, Electrical, Avionics & Naval Marine Engineering Support. Understanding how contracting officers cross-walk PSC R425 with NAICS 541330 is critical because many agencies filter dynamic small business searches, GSA e-Buy distributions, and historical FPDS incumbent spend analyses by PSC rather than NAICS alone. Procurement teams issuing awards under PSC R425 utilize a mix of open-market SAM.gov solicitations and pre-competed contract vehicles such as GSA MAS 541330. Depending on the acquisition threshold and market research results from Sources Sought notices, contracting officers frequently restrict PSC R425 competitions to certified small businesses—including 8(a) Business Development participants, Service-Disabled Veteran-Owned Small Businesses (SDVOSB), Women-Owned Small Businesses (WOSB), and HUBZone firms. Offerors responding to PSC R425 RFPs must demonstrate strict compliance with applicable FAR and DFARS clauses, deliverable quality standards, and supply-chain or labor regulations. For contractors expanding across both federal and state/local (SLED) markets, PSC R425 maps directly to NIGP Commodity/Service Code 925-36 (Engineering Services, General Professional (Multi-Disciplinary & Systems)) used by state procurement portals, municipal purchasing departments, public universities, and K-12 school districts. InTandem's automated government contracting platform continuously monitors live SAM.gov notices tagged with PSC R425 alongside matching state and local NIGP 925-36 bids, enabling capture teams to uncover hidden opportunities and generate compliant proposals faster.
