UNSPSC 31163007: Chain coupling

Coupling that uses double roller chain to connect two hubs.

UNSPSC 31163007 Chain coupling is a Commodity code that covers fasteners and mechanical linkages used in equipment assembly and maintenance across state and local government operations. Recent state and local solicitations under this code reveal that purchasing offices are acquiring chain coupling components as part of broader hardware and transportation maintenance procurement — notably through cooperative purchasing vehicles that bundle chain coupling with hooks, shackles, lifting hardware, and other industrial fasteners into catalog discount arrangements. The issuing bodies include county purchasing cooperatives, city procurement departments acting on behalf of multiple jurisdictions, and state-level cooperative purchasing organizations such as Sourcewell. These entities solicit chain coupling alongside related mechanical hardware for use by public works departments, law enforcement, transportation maintenance divisions, and other operational units within government.

Geographic activity centers on the Pacific Northwest and South-Central United States, with recent solicitations posted by Sourcewell (Minnesota-based cooperative serving multiple states including Washington counties), Region 7 Purchasing Cooperative (Texas-based, serving multiple jurisdictions), and the City of Tampa on behalf of Hillsborough County (Florida). The most recent representative opportunity is the City of Tampa RFQ 26-P-00214 for hooks and shackles, posted March 18, 2026, with response due April 15, 2026, which encompasses chain components alongside other fastening hardware for city and county departmental use. Region 7 Purchasing Cooperative's RFP for Transportation Maintenance & Supplies (TRAN2426), posted April 8, 2026, with a November 21, 2024 deadline, targets a two-year contract valued at $10,423,151.00 and attracted 120 respondents in the previous award cycle, indicating significant vendor competition for cooperative purchasing arrangements that include chain coupling within broader maintenance supply catalogs.
