UNSPSC 31133704: Diamond metal matrix powdered metal and metal alloy

Powdered composite comprising diamond powder and a powdered metal or metals

UNSPSC 31133704 Diamond metal matrix powdered metal and metal alloy is a Commodity code that shows no current alignment with recent state and local procurement activity. The code's nominal scope—powdered metal and metal alloy composites—does not match the work documented in the most recent state and local solicitations tagged under it. The four recent opportunities include mobile welding and fabrication services (Hillsborough County, Florida), coiled aluminum for correctional-industries license plate production (Colorado Department of Corrections, multiple solicitations), and pallet rack wire decking for a court facility (Los Angeles Superior Court). None of these procurements involve diamond metal matrix materials or powdered metal alloys as the code describes them.

The recent activity reflects a misclassification or data-management issue in the state and local procurement systems that posted these opportunities. Hillsborough County's ITB for mobile welding covers labor and standard materials (steel plates, angle iron, tubing, pipe) for equipment repair at solid waste facilities. Colorado Correctional Industries issued multiple IFBs and ITBs for coiled aluminum alloy (3105H21, 21-gauge thickness) to feed license plate production, with quantities ranging from 10,000 to 350,000 pounds and delivery to Canon City. Los Angeles Superior Court's RFQ targets wire decking for pallet racks (52" × 42", 2,500-pound load capacity). These are routine maintenance, industrial supplies, and facility goods procurements unrelated to powder metallurgy or composite materials. Bidders targeting the code as currently indexed will encounter systematic mismatch between the code designation and the actual work scope.
