UNSPSC 31101814: Tin shell mold casting

Tin object cast from shell molds

UNSPSC 31101814 Tin shell mold casting is a Commodity code, but the recent state and local procurement activity under this code shows no alignment with tin shell molding or casting operations. The City of Atlanta Department of Watershed Management issued a Pre-Advertisement Notice (PE66062NONST2026000000372) on May 8, 2026, with a response date of May 29, 2026, seeking vendors to provide repair, maintenance, installation, and parts replacement services for nine classifications of pumps — Vertical Turbine, Horizontal Split Case, Submersible, Centrifugal, Vertical Chopper, Progressing Cavity, Piston Type Positive Displacement, Watson Marlow, and Vacuum and Hydraulic pumps. The solicitation requires successful bidders to own or have full access to 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. Work must comply with OSHA standards, lock out/tag out procedures, and manufacturer safety recommendations. Vendors must supply 90 percent of required parts within 24 hours and the remaining 10 percent within 72 hours, provide a one-year warranty on parts and services, and submit itemized annual purchase reports. Watson Marlow pump work must be performed by manufacturer-certified distributors, and Flygt pump work must be performed by Xylem manufacturer-certified distributors. Vendors provide their own tools, equipment, and safety equipment, with all costs for plant and facility inspections borne by the vendor.

The code shows no recent state or local procurement activity in tin shell mold casting. The single recent opportunity tagged to this code concerns pump repair and maintenance services in Georgia and does not involve casting or molding work of any kind. Buyers seeking tin shell casting vendors should not rely on this code for market signals; the mismatch suggests a classification error in the underlying opportunity record.
