UNSPSC 23181509: Sorting machinery

UNSPSC 23181509 Sorting machinery is a Commodity code covering the procurement of sorting and screening equipment and related services for material segregation and processing. State and local governments buy under this code primarily for waste management and materials processing operations — specifically, the acquisition of machinery and labor services to screen, sort, and categorize construction spoils, landfill materials, and aggregates into specified size and quality categories for reuse or disposal. The Maryland Environmental Service issued a competitive sealed bid solicitation in May 2026 for rock and material screening and sorting services at the Harford Waste Disposal Center in Harford County, soliciting qualified contractors to provide the labor, materials, equipment, and permits necessary to segregate approximately 130,000 cubic yards of blasted rock spoils into five material categories ranging from stones greater than 18 inches down to 1.5-4 inch stone, with all materials to be stockpiled on-site. The procurement carries a 15 percent Minority Business Enterprise subcontract participation goal and is designated as a Small Business Reserve procurement, limiting award eligibility to businesses certified by the Governor's Office of Small, Minority & Women Business Affairs. The soliciting body is a state environmental agency, reflecting the typical use of this code for public works and remediation projects where waste material processing is a core project requirement.

Activity under this code appears limited in recent postings. The Maryland Environmental Service's Harford Waste Disposal Center solicitation, posted May 6, 2026, with bids due June 8, 2026, represents the primary documented recent opportunity. This IFB requires bidders to price three distinct bid items based on estimated material volumes, with a pre-bid conference held May 12, 2026, site visits available through May 22, 2026, and performance bonds required at 100 percent of contract value when the base bid exceeds $100,000. The solicitation reflects procurement concentrated in Maryland, with no indication of parallel activity in other states or jurisdictions in the available data.
