UNSPSC 23151604: Grinding or polishing machines

UNSPSC 23151604 Grinding or polishing machines is a Commodity code that encompasses industrial grinding equipment and services purchased by state and local government entities for materials processing and waste management applications. Recent solicitations show the code applied principally to wood and green waste grinding services rather than to the abstract machinery category alone. Ada County, Idaho's RFP 26040, posted April 2, 2026, and due May 5, 2026, sought wood and green waste grinding services at the Ada County Landfill, processing 8,000 to 12,000 tons of green and wood waste annually to specifications of 1.0" to 2.0" screen size with a minimum of 90% passing a 2-inch screen; the county required pricing on a per-ton basis incorporating all labor, equipment, fuel, mobilization, demobilization, dust control, and contamination removal costs, with an optional pre-proposal meeting held April 14, 2026. The issuing bodies under this code reflect a mix of local government entities — counties and county service centers — pursuing waste management and materials processing contracts on an as-needed or annual basis. Evaluation criteria across recent opportunities emphasize relevant experience with governmental entities, compliance with technical specifications, approach and project management, and cost competitiveness weighted equally or above compliance.

Geographic activity under the code centers on the Mountain West and Southwest regions, with Ada County, Idaho representing the most concrete recent opportunity. The broader recent opportunities block shows education-focused cooperative purchasing through Region 7 (Texas), a Sourcewell law-enforcement equipment RFP spanning multiple Washington state counties, and a Columbus, Georgia parks-and-recreation supplies procurement — none of which align with grinding or polishing machinery scope. The Ada County landfill grinding RFP stands as the only recent solicitation meaningfully tied to UNSPSC 23151604's stated commodity category; other opportunities in the block appear misfiled against the code. Ada County's contract term extends through September 30, 2027, with optional renewal for each subsequent fiscal year contingent on appropriations, and the county reserves award flexibility to reject any proposals or select multiple vendors based on per-ton pricing submissions evaluated at 30 percent of the 100-point evaluation scale.
