About UNSPSC 31121520

UNSPSC 31121520 Ductile iron shell mold machined casting is a Commodity code that covers ductile iron pipe components, fittings, and related parts sourced by state and local water utilities and public works departments. State and local governments procure under this code primarily large-diameter ductile iron pipe sections, gland retainers, tapping sleeves, saddles, spools, and repair parts used in water distribution infrastructure. The issuing bodies are predominantly county water resource departments and municipal public works agencies, with Gwinnett County, Georgia appearing as a repeat buyer across multiple informal written quotations (IWQs) since May 2026 and the City of Dallas and City of Southlake, Texas establishing longer-term supply agreements.
