UNSPSC 31101909: Tin investment casting

Tin object cast from investment molds

UNSPSC 31101909 Tin investment casting is a Commodity code that in recent state and local procurement reflects little activity directly aligned with the code's nominal scope. The single recent opportunity tagged to this code — the City of Atlanta Department of Watershed Management's May 2026 IFB for pump repair, maintenance, installation, and parts replacement services — involves no tin investment casting work. The solicitation targets multi-group pump servicing across nine classifications (Vertical Turbine, Horizontal Split Case, Submersible, Centrifugal, Vertical Chopper, Progressing Cavity, Piston Type Positive Displacement, Watson Marlow, and Vacuum and Hydraulic pumps), with vendors required to perform full-service support including procurement, disassembly, detailed inspection, transportation, OEM-standard repair, reassembly, startup, and photographic documentation. Vendors must own or access a functional machine shop, field service equipment, and personnel certified in pump shaft alignment, welding, and machinist work, with confined-space-entry training, OSHA and lock-out/tag-out compliance, and manufacturer safety standards throughout. This mismatch suggests the code sees minimal relevant state and local procurement activity at present, or that tagging errors have obscured genuine casting or metalworking opportunities under different UNSPSC classifications.

The City of Atlanta opportunity, posted May 8, 2026 with a May 29, 2026 response deadline, requires vendors to supply 90 percent of parts within 24 hours and the remaining 10 percent within 72 hours, provide one-year warranties on parts and services, and submit itemized annual purchase reports to the Chief Procurement Officer within 15 days of contract anniversary. A prequalification phase precedes the formal IFB, with a pre-solicitation conference planned to clarify scope. No set-aside designations or incumbent vendors are identified; Watson Marlow work must be performed by manufacturer-certified distributors and Xylem-certified distributors for Flygt pumps. Payment terms offer a five percent discount for payment within 10 days, otherwise net 30. No award value or minimum contract amount is disclosed. The code shows no other recent state or local opportunities and does not reflect active procurement momentum for tin investment casting work.
