UNSPSC 31151600: Chains

UNSPSC 31151600 Chains, a Class code, encompasses the procurement of specialized chain products in various grades, materials, and sizes to support municipal operational needs across departments. State and local governments soliciting under this code are sourcing inventory-replenishment and equipment-support chains — including transport grade 70 chain, alloy steel grade 100 chain, proof coil galvanized chain in multiple diameters, and zinc chain — with specific technical specifications tied to lifting, securing, and load-bearing applications. The issuing bodies are primarily municipal purchasing departments representing multiple jurisdictions; the City of Tampa Purchasing Department has posted at least one recent opportunity under or adjacent to this code on behalf of Hillsborough County and Tampa municipal divisions, and the code sees activity from general-purpose local government procurement offices handling routine operational supplies across multiple departments simultaneously.

The geographic activity centers on Florida, with recent opportunities posted by the City of Tampa (solicitation 26P00328, Chain for Inventory, RFQ posted May 12, 2026, with response deadline June 15, 2026, seeking six line items of specialized chain with FOB Destination delivery within five business days and one-year contract term). The City of Tampa has also posted related lifting and securing hardware solicitations (26P00214, Hooks and Shackles, RFQ posted March 18, 2026, due April 15, 2026) covering chains alongside shackles, hooks, and slings. A separate cooperative purchasing vehicle through Sourcewell (Minnesota local government unit) issued RFP 061626 for Law Enforcement Equipment with a June 16, 2026 deadline, though the connection between law enforcement equipment and the narrow chain commodity scope is unclear and this opportunity may represent a mismatch in code assignment. Evaluation criteria across Tampa-issued opportunities center on competitive pricing with all freight and handling included, compliance with Florida E-Verify and public records requirements, proof of insurance prior to award, and flexible award authority by line item, division, or aggregate total.
