UNSPSC 31151604: Proof coil chains

UNSPSC 31151604 Proof coil chains is a Commodity code that encompasses industrial-grade chain products used by state and local government departments for inventory, operational support, and equipment maintenance. The specific work being solicited involves supply of proof coil chains in various gauges and finishes—typically galvanized or zinc-plated, in grades 30 and higher, with working load limits ranging from 800 pounds and above—along with complementary lifting and securing hardware such as hooks, shackles, and tie-down straps. State and local issuing bodies under this code include municipalities (City of Tampa), counties (Hillsborough County), and cooperative purchasing vehicles (Sourcewell, a Minnesota local government unit). The City of Tampa has been a repeat buyer, with multiple recent RFQs for chain inventory and related hardware spanning municipal and county operational divisions.

Recent activity concentrates in Florida and Washington state. The City of Tampa Purchasing Department issued RFQ 26P00328 on behalf of Hillsborough County and City of Tampa departments in May 2026, requesting six line items of specialized chain products including 3/8-inch transport-grade 70 chain, alloy steel grade 100 chain, and multiple specifications of proof coil chains in galvanized finishes (Grade 30), with a submission deadline of June 15, 2026 and FOB Destination delivery within five business days of order. A related opportunity, RFQ 26P00214, issued by Tampa in March 2026 for hooks, shackles, and chain-related hardware across 20 line items, with an April 15, 2026 response date. Separately, Sourcewell (State of Minnesota) issued RFP 061626 in May 2026 for law enforcement equipment on behalf of participating counties in Washington state (Franklin, Grant, Grays Harbor, Chelan, and Yakima) and broader public-sector entities, with a June 16, 2026 proposal deadline. All solicitations require electronic submission, firm fixed pricing inclusive of freight on FOB Destination terms, and proof of insurance prior to award, with contract periods of one year and City or cooperative discretion to award by line item, division, or aggregate total.
