UNSPSC 51131630 Clorindione is a Commodity code that encompasses chemical herbicide products and related supplies purchased by state and local law enforcement and public safety agencies. The single recent opportunity in the source—Sourcewell RFP #061626 for Law Enforcement Equipment, posted May 12, 2026 with response due June 16, 2026—tags this code but appears misaligned with the code's nominal herbicide scope, listing it generically under "law enforcement equipment" rather than specifying chemical or herbicide procurement. The issuing body is Sourcewell, a Minnesota local government unit and service cooperative acting as the contracting vehicle on behalf of multiple participating entities including Franklin, Grant, Grays Harbor, Chelan, and Yakima Counties in Washington, along with other jurisdictions, public entities, K-12 school districts, higher education institutions, nonprofit organizations, and tribal governments throughout the United States and Canada. The solicitation structure allows the resulting contract to serve thousands of governmental agencies across a broad geographic footprint.

The recent activity is concentrated in Washington state, where five named counties are active participants, though the cooperative purchasing model extends eligibility nationwide and into Canada. The single posted opportunity does not specify award value, set-aside designations, or incumbent vendors. Vendors must submit proposals through the Sourcewell Procurement Portal by June 16, 2026 at 3:30 p.m. Central Time; contact Mari Vielma at rfp@sourcewell-mn.gov or 888-894-1930 for procurement inquiries. The code shows limited recent relevant activity—the single opportunity in the source does not clearly articulate a herbicide or chemical procurement need, and no other state or local opportunities under this Commodity code appear in the record.
