UNSPSC 23181504: Sifting machinery

UNSPSC 23181504 Sifting machinery (Commodity) covers equipment for separating or grading materials by particle size, the kind of machinery state and local governments procure for public works, water and wastewater treatment, recycling operations, and aggregate processing at municipal facilities. State and local issuing bodies soliciting under this code include county departments of public works, city engineering and utilities departments, municipal water authorities, and waste management districts that maintain screening and classification equipment for construction materials, compost processing, sand and gravel operations, and treatment plant operations.

No recent state and local contract opportunities appear in the available records for this code. The absence of recent activity suggests either low procurement frequency — sifting machinery is typically a capital equipment purchase with long intervals between replacements — or that issuing bodies are sourcing replacement equipment and parts through existing framework agreements or open market purchases rather than formal solicitations.
