UNSPSC 31121222: Ductile iron sand machined casting

Ductile iron object cast from sand molds that has been machined

UNSPSC 31121222 Ductile iron sand machined casting (Commodity) covers large-diameter ductile iron pipe components, fittings, and repair parts that state and local water utilities procure for distribution system maintenance and expansion. Recent solicitations show governments buying 30-inch diameter pipe sections, gland retainers, tapping sleeves, saddles, and ductile iron spools—components specified to exact standards (Class 250 rating, EBBA 1130 specifications, slip-joint cement lining) and typically delivered FOB Destination to municipal water facilities. Gwinnett County, Georgia's Department of Water Resources emerges as a repeat buyer, issuing multiple informal written quotations (IWQs) for large-diameter ductile parts between May and September 2026. Cities also procure under this code: Dallas established a five-year master agreement for ductile iron pipe supply to its Water Utilities department, and Southlake sought utility parts and supplies for its Department of Public Works. Issuing bodies are primarily municipal water departments and county water authorities; most recent solicitations use informal quotation procedures with short response windows (three to five days) rather than formal RFPs.

Activity concentrates in Georgia and Texas. Gwinnett County has posted seven ductile iron component solicitations since May 2026, with quotes due September 18, 2026 for large-diameter ductile parts (PE77023NONST2027000000745 and PE77023NONST2027000000743) requiring acknowledgment of addenda and delivery to the DWR Central Facility in Lawrenceville. The City of Dallas issued a competitive bid on May 14, 2026 for a five-year ID/IQ master agreement for ductile iron pipe (BG2600030409, due June 12, 2026), potentially covering ongoing supply needs. Vendors responding to Gwinnett County solicitations must provide three project references, certify non-collusion, comply with Georgia Illegal Immigration Reform requirements, hold valid occupation tax certificates, and avoid the Gwinnett County ineligible source list. FOB Destination Prepaid and Allowed terms are standard; delivery windows are typically restricted to Monday–Friday, 9:00 a.m. to 4:00 p.m. No bid, performance, or payment bonds are required for smaller awards.
