UNSPSC 32101503: Mixed circuit assemblies

UNSPSC 32101503 Mixed circuit assemblies (Commodity) encompasses custom printed circuit boards and related electronic components for specialized applications. State and local governments purchase these items primarily for infrastructure modernization, security systems, and operational equipment maintenance. Recent solicitations show universities and public utilities buying custom PCBs for specific equipment retrofits, while school districts, counties, and municipalities procure circuit board assemblies as components within larger security and safety system contracts. The issuing bodies span higher education institutions, county water authorities, school districts, and municipal utilities — a diverse mix reflecting the embedded nature of circuit boards across facility operations and security infrastructure.

Geographic activity concentrates in the upper Midwest and Southwest. The University of Wisconsin-Madison sought APxF Rev K3 Custom Printed Circuit Boards under RFB 2027-UWMSN-01396 with responses due July 20, 2026. Riverside County, California issued RFB 3918 on March 3, 2026 for an ABB ACS880-04 AC Drive Module (a specialized circuit assembly) with a March 25, 2026 deadline. The School Board of Sarasota County, Florida's ITB 26-0158 for safety and security systems included circuit board assemblies and control components across 52 school locations, with responses due March 10, 2026. The City of Phoenix Public Works Department solicited electrical parts and supplies (including circuit board components) under IFB 26-FMD-012 with a July 9, 2025 deadline. Activity also reflects cooperative purchasing vehicles — Sourcewell's RFP 061626 for law enforcement equipment, posted May 12, 2026 with a June 16, 2026 deadline, positioned circuit board assemblies and control systems for use across multiple Washington state counties and national jurisdictions. The code sees relatively modest recent activity volume, with opportunities appearing sporadically rather than as sustained procurement demand.
