UNSPSC 51131605 Sodium citrate is a Commodity code with minimal recent state and local procurement activity tied to its nominal scope. The single recent opportunity tagged to this code — Sourcewell RFP #061626 — solicits law enforcement equipment broadly, not sodium citrate or chemical reagents specifically. The mismatch between the code's chemical-product definition and the actual procurement being sought suggests this code does not reflect current state and local government buying patterns or that the opportunity was miscategorized by the issuing body.

Sourcewell, a Minnesota local government unit and service cooperative, issued RFP #061626 on May 12, 2026, with a response deadline of June 16, 2026 at 3:30 p.m. Central Time, covering law enforcement equipment for thousands of governmental agencies, higher education institutions, school districts, nonprofits, and tribal governments across the United States and Canada. The cooperative structure includes participation from Washington counties (Franklin, Grant, Grays Harbor, Chelan, and Yakima) and numerous other jurisdictions. The solicitation provides no explicit set-aside designations, incumbent vendor names, or award values in the available documentation. Vendors must submit proposals exclusively through the Sourcewell Procurement Portal; no bid documents are available through Washington's WEBS system. Questions should be directed to Mari Vielma at rfp@sourcewell-mn.gov or 888-894-1930.
