UNSPSC 32131018: Heavy layer copper bare printed circuit board

A type of printed circuit board with a heavier than normal layer of Cu, greater than 200 microns in thickness, with no components; used in applications of high power distribution, heat dissipation and the like.

UNSPSC 32131018 Heavy layer copper bare printed circuit board is a Commodity code, but the recent state and local contract opportunities do not reflect procurement activity under this code. The five most recent opportunities posted under this classification span law enforcement equipment (Sourcewell cooperative purchasing), school security systems and services (Sarasota County), electrical parts and supplies (City of Phoenix), an AC drive module (Riverside County water district), and printing and mailing services (City of Madison) — none of which align with custom or bare printed circuit boards. The single opportunity with direct relevance is the University of Wisconsin-Madison's IFB for APxF Rev K3 Custom Printed Circuit Boards (2027-UWMSN-01396-RFB), due July 20, 2026, submitted through ShopUW+.

The code shows minimal recent activity in state and local procurement. Beyond the University of Wisconsin-Madison solicitation, the opportunities tagged under this code appear to be classification errors or system artifacts rather than genuine printed circuit board procurements. The Wisconsin solicitation represents the only concrete signal of current demand under the code's nominal scope. Firms evaluating this Commodity code should verify their product alignment directly with issuing bodies rather than relying on the recent opportunity record, and should monitor university procurement channels and electronics assembly vendors in Wisconsin as the primary near-term market segment.
