UNSPSC 31101905: Iron investment casting

Iron object cast from investment molds

UNSPSC 31101905 Iron investment casting (Commodity) represents metal casting products used in industrial equipment and infrastructure applications. While the code's nominal scope covers cast iron components, state and local procurement activity under this code appears limited, with recent solicitations showing minimal direct alignment to iron investment casting as a standalone commodity. The one recent opportunity on file—the City of Atlanta Department of Watershed Management's May 2026 notice for pump repair and parts services—does not explicitly procure cast iron components but rather full-service pump maintenance, repair, and replacement parts across nine pump classifications, suggesting the code may be applied inconsistently or capture only incidental casting purchases within larger service contracts.

The recent Atlanta solicitation, posted May 8, 2026 with a prequalification deadline of May 29, 2026, follows a multi-step sealed bid process requiring vendors to provide comprehensive pump support including parts procurement, installation, repair to OEM standards, and field services. The scope encompasses 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 supply 90 percent of parts within 24 hours and the remainder within 72 hours. No award value is disclosed. Given the sparse recent activity under this code, firms should verify directly with state and local procurement offices whether casting-related opportunities are tagged under alternative UNSPSC codes or remain episodic within larger equipment or maintenance contracts.
