UNSPSC 31101817: Ductile iron shell mold casting

Ductile iron object cast from shell molds

UNSPSC 31101817 Ductile iron shell mold casting (Commodity) does not align with the state and local procurement activity currently appearing under this code. The single recent opportunity on record—the City of Atlanta Department of Watershed Management's multi-step sealed bid process posted May 8, 2026—solicits pump repair, maintenance, installation, and parts replacement services for nine classifications of pumps (vertical turbine, horizontal split case, submersible, centrifugal, vertical chopper, progressing cavity, piston positive displacement, Watson Marlow, and vacuum/hydraulic), not ductile iron castings. The scope requires vendors to own or access a functional machine shop, field service equipment, and personnel certified in pump shaft alignment, welding, and machinist work, with personnel trained in permit-required confined space entry. Vendors must supply 90 percent of required parts within 24 hours and the remaining 10 percent within 72 hours, provide one-year warranty on parts and services, and comply with OSHA standards and manufacturer safety recommendations. Watson Marlow pump work must be performed by manufacturer-certified distributors; Flygt pump work by Xylem manufacturer-certified distributors. This is a utility department procurement, not a manufacturing or foundry supplier category.

The code shows little relevant recent activity in Georgia or elsewhere, with the single indexed opportunity representing a clear mismatch between the code's nominal scope and the actual work being purchased. Business development professionals should verify whether the City of Atlanta or other municipalities have misfiled this pump services solicitation under a casting code, or whether the code classification itself requires clarification. The response deadline for the Atlanta IFB prequalification phase is May 29, 2026; however, this opportunity does not represent typical or ongoing purchasing under UNSPSC 31101817.
