UNSPSC 40171503: Commercial ductile iron pipe

Pipe with a pressure rating of 2500 psi or less made of ductile iron

UNSPSC 40171503 Commercial ductile iron pipe is a Commodity code describing the supply of ductile iron water mains and related piping materials that state and local water utilities, public works departments, and special-purpose water authorities procure for system expansion, replacement, and infrastructure rehabilitation. Recent solicitations span a wide geographic area and issuing-body mix that includes city water utilities (Phoenix, Dallas, Madison, Sarasota, Palm Bay, Calhoun), county water and sewerage authorities (DeKalb County Georgia, Cherokee County Water and Sewerage Authority, Beaufort-Jasper Water & Sewer Authority), and regional special-purpose districts (Gwinnett County, Franklin County Board of Commissioners, Bryan County Board of Commissioners). The scope of work under this code encompasses direct commodity supply of ductile iron pipe in multiple diameters (ranging from 6 inches to 30 inches) and pressure classes, often bundled with associated fittings, valves, hydrants, and related appurtenances, with delivery on as-needed or materials-only bases to support water main installation, interconnection, replacement, and rehabilitation projects. Contracts typically run one to five years with firm pricing on an F.O.B. destination basis, 24-to-48-hour delivery expectations, and compliance with ANSI/AWWA standards and approved materials lists; many include American Iron and Steel or Build America, Buy America Act requirements mandating domestic sourcing.

Recent activity is concentrated in the Southeast and Southwest, with standout recent procurements including the City of Phoenix Public Works Department IFB 26SW0379 (industrial pipe and fittings supply, three-year term commencing December 1, 2026, due August 12, 2026), the City of Dallas competitive bid for a five-year indefinite-delivery master agreement for ductile iron pipe (due June 12, 2026), the City of Madison RFQs for ductile iron pipe and tapping sleeves (due March 17, 2026), and DeKalb County Georgia ITB 2026-036 for ductile iron water pipe on a three-year multiyear contract (due July 2, 2026). Several procurement notices also embed ductile iron pipe supply within larger water infrastructure projects: Cherokee County Water and Sewerage Authority seeking 24,100 linear feet of DIP water main for State Route 20 widening (sealed bids due April 9, 2026), Beaufort-Jasper Water & Sewer Authority soliciting 16-inch steel waterline rehabilitation via polyethylene liner or CIPP (IFB due March 4, 2026), and the City of Calhoun requesting materials for water main relocation including 3,740 feet of 12-, 8-, and 6-inch ductile iron main (due June 18, 2026). Set-asides and preferences appear selectively: Phoenix requires DBE-Neutral compliance under 49 CFR Part 26; Beaufort-Jasper mandates SMWBE good faith efforts; Pinellas County targets 8 percent SBE subcontractor participation; and Madison extends local vendor preference scoring. Activity is active and ongoing across July 2026.
