UNSPSC 31163007: Chain coupling

Coupling that uses double roller chain to connect two hubs.

UNSPSC 31163007 Chain coupling is a Commodity code that captures mechanical fastening and coupling components used across state and local government operations. The recent solicitation activity under this code, however, shows a disconnect between the nominal scope and what state and local buyers are actually procuring: Sourcewell, a Minnesota cooperative purchasing vehicle, issued RFP #061626 in May 2026 on behalf of participating counties across Washington State (Franklin, Grant, Grays Harbor, Chelan, and Yakima) and numerous other jurisdictions nationwide to establish a framework agreement for law enforcement equipment. The RFP targets a broad range of public entities — counties, cities, school districts, higher education, tribal governments, and nonprofits — but the solicitation materials do not itemize specific equipment classes or distinguish whether chain couplings are a material component of the law enforcement equipment category being sought. The issuing body mix reflects the cooperative structure: Sourcewell administers the procurement on behalf of multiple state and local jurisdictions across the United States and Canada, with particular activity in Washington State counties and participation available to K-12 school districts, transit authorities, and other special-purpose districts through the cooperative framework.

The geographic spread centers on Washington State counties named in the opportunity (Franklin, Grant, Grays Harbor, Chelan, Yakima) with broader reach across the United States and Canada through Sourcewell's participating addendum model. The RFP #061626, due June 16, 2026, was posted May 12, 2026, and requires submission through the Sourcewell Procurement Portal; vendors must create an account to access solicitation documents and amendments. Questions and clarifications are handled through the portal's Q&A feature or directed to Mari Vielma at rfp@sourcewell-mn.gov or 888-894-1930. The solicitation does not identify specific dollar values, set-aside designations, incumbent vendors, or explicit component requirements tied to chain couplings, suggesting that chain-coupling procurement under this code may be incidental to broader law enforcement equipment contracts rather than a primary commodity line within state and local government buying patterns.
