UNSPSC 23153100: Industrial machinery components and accessories

UNSPSC 23153100 Industrial machinery components and accessories is a Class code under which state and local governments procure components for rotating equipment maintenance and repair, bearings, belts, gears, couplings, and similar replacement parts, as well as specialized industrial systems including wastewater treatment pumps and cold-storage refrigeration units. Recent solicitations show government buyers purchasing both commodity-grade components (such as pilot-operated relief valves and pump assemblies for municipal wastewater systems) and engineered, application-specific equipment such as lime-sludge dewatering belt filter presses and walk-in commercial freezers. The mix of issuing bodies spans county governments (Collier County, Palm Beach County, Gwinnett County, Orange County, and Hillsborough County in Florida and Georgia), a regional special-purpose district (Monterey-Salinas Transit), and school systems (Seminole County), with no single repeat buyer dominating the activity. Work ranges from routine maintenance contracts for industrial laundry equipment to capital replacement projects for specialized treatment systems and facility infrastructure.

Recent activity concentrates in Florida and Georgia, with secondary activity in Texas, Connecticut, and California. Representative solicitations include Collier County's notice of intent to single-source Alfa Laval lime sludge dewatering belt filter press equipment (contract term October 2026–September 2029); Gwinnett County's sealed-bid solicitation for Sheriff's Office Freezer #8 replacement with walk-in refrigeration systems and associated evaporator and condensing units (bids due August 7, 2026, via IFB PE77023NONST2027000000662); Palm Beach County's ongoing request for pre-qualification of industrial machinery components vendors (parts, gears, sprockets, bearings, chains, and couplings on an as-needed basis with a 60-month term and $208,500 estimated funding); and Monterey-Salinas Transit's RFI for removal of in-ground vehicle lifts and concrete slab restoration (responses due June 18, 2026). Counties and special districts use cooperative pre-qualification and on-call contracting vehicles to manage intermittent component and repair needs; Palm Beach County's pre-qual model explicitly incorporates local and Glades-area business preference and S/M/WBE set-asides. Award thresholds typically trigger formal competitive bidding for projects exceeding $99,999–$100,000.
