UNSPSC 31151604: Proof coil chains

UNSPSC 31151604 Proof coil chains, a Commodity code, covers industrial-grade chains for municipal operations, particularly proof coil and transport grade variants used by city and county departments for inventory management and equipment support. State and local governments procure these chains in relatively small quantities — typically 100 to 800 feet per line item — for use across multiple operational divisions including maintenance, public works, and law enforcement functions. The City of Tampa and Hillsborough County represent the most visible recent buyer, sourcing multiple proof coil specifications (3/16 inch, 1/4 inch, and 3/8 inch grades, commonly Grade 30 HD galvanized and alloy steel Grade 100) through direct RFQ to support ongoing municipal needs. Beyond direct municipal procurement, cooperative purchasing vehicles such as Sourcewell distribute chain and related law enforcement equipment contracts across multiple counties and public entities, expanding the addressable market to school districts, tribal governments, and nonprofit organizations.

Recent activity clusters in Washington state and Florida. The City of Tampa issued RFQ 26P00328 on May 12, 2026, with a June 15, 2026 response date, specifying named brands (Gunnebo, Campbell Weis) and tight delivery requirements (five business days FOB Destination, backorder fulfillment within three working days). Sourcewell's RFP #061626, posted May 12, 2026 with a June 16, 2026 deadline, represents a cooperative vehicle spanning Franklin, Grant, Grays Harbor, Chelan, and Yakima Counties in Washington, plus jurisdictions across the United States and Canada. Both opportunities emphasize price competition and commodity-level contracting with no disclosed set-asides or incumbent restrictions. Payment terms run approximately 30 days post-delivery and acceptance.
