UNSPSC 31101814: Tin shell mold casting

Tin object cast from shell molds

UNSPSC 31101814 Tin shell mold casting is a Commodity code with minimal recent state and local procurement activity aligned to its nominal scope. The single recent opportunity tagged to this code — the City of Atlanta Department of Watershed Management's May 2026 solicitation for pump repair, maintenance, installation, and parts replacement services — does not involve tin shell mold casting or foundry work. The opportunity solicits comprehensive pump service capability across nine pump classifications, including vertical turbine, horizontal split case, submersible, centrifugal, vertical chopper, progressing cavity, piston positive displacement, Watson Marlow, and vacuum and hydraulic pumps, with vendors required to demonstrate full machine-shop infrastructure, certified field personnel, OEM-standard repair capability, and compliance with OSHA and confined-space-entry protocols. The mismatch between the code's casting focus and the pump-services scope suggests the code sees little current procurement traffic that aligns with tin shell mold casting as state and local governments actually buy it.

The single identified opportunity is a multi-step sealed bid process issued by the City of Atlanta (Fulton County, Georgia) with a prequalification phase followed by an Invitation for Bid (IFB), due May 29, 2026. No geographic spread beyond Georgia or issuing-body diversity is evident from the source; no other recent state or local opportunities under this code appear in the available record. State and local procurement professionals should treat this code as inactive for tin shell mold casting purposes and monitor whether future opportunities under it demonstrate greater alignment to foundry work or continue to reflect service-sector misclassification.
