UNSPSC 40183206: Iron tube assembly

Iron tube assembly

UNSPSC 40183206 Iron tube assembly is a Commodity code capturing industrial piping materials, fittings, and related appurtenances that state and local governments procure for water infrastructure, stormwater systems, and utility operations. State and local buyers under this code are primarily cities and counties acquiring pipe stock, fittings, valves, fire hydrants, and accessories on as-needed or project-specific bases. Recent solicitations show work ranging from on-call supply agreements with 24–48 hour delivery windows to one-time material bids for water main replacements and infrastructure rehabilitation. The City of Phoenix Public Works Department (IFB 26-SW-0379, due August 12, 2026) seeks industrial pipe including High-Density Polyethylene and Polyvinyl Chloride pipe in diameters from 0.75 to 24 inches, plus fittings, glue, and hand tools on an as-needed basis with three-year contract terms. The City of Sarasota (ITB #26-31JS) requested materials-only bids for pipe, fittings, and appurtenances conforming to its Potable Water Approved Material List for the Small AC Water Main Replacement project. The City of Calhoun, Georgia (Bid #2026-00299) solicited ductile iron water mains in 12-, 8-, and 6-inch sizes alongside PVC piping, mechanical joint fittings, gate valves, and fire hydrants for a 3,740-foot water main relocation. Orange County, Florida (Y26-126) sought sewer pipes and fittings across 56 line items including PVC and ductile iron pipes with an estimated five-year spending total of approximately $28.7 million.

Geographic concentration is heaviest in Florida, with multiple cities and Orange County posting recent solicitations, followed by Georgia and Arizona. The issuing-body mix spans municipal public works and utilities departments, county water and sewer authorities, and regional transit agencies subject to federal transit compliance requirements such as Disadvantaged Business Enterprise participation. Recent activity shows strong demand in the Southeast and Southwest, with particular intensity in Florida's coastal and municipal corridors where water main and stormwater infrastructure upgrades are ongoing. Pricing structures typically require firm fixed pricing over contract terms, with delivery obligations ranging from same-day emergency response (four hours in some cases) to standard delivery within 24–90 days depending on inventory status and order size. Compliance with American Iron and Steel and Buy American Act provisions appears frequently, and vendors must often maintain local inventory, provide dedicated contract representatives, and meet stringent warranty and responsiveness standards. Set-asides and preferences vary by issuer—Phoenix applies DBE-N compliance under Federal Transit Administration standards, Dallas applies a 5% local price preference for Dallas-based firms, and Orange County applies Service Disabled Veteran Business preference tiers.
