UNSPSC 23151907: Screen drum or sieve

A device of wire mesh or closely perforated metal, used for straining, sifting, ricing, or pureeing a filter to retain larger pieces while smaller pieces and liquids pass through.

UNSPSC 23151907 Screen drum or sieve is a Commodity code that in recent state and local procurement shows almost no activity aligned to the code's nominal scope. The City of Philadelphia has posted six flat printing solicitations under this code since April 2026—for Town Watch palm cards, real estate tax billing materials, door hangers, and wellness pamphlets—none of which involve screening, sieving, or the equipment this code describes. A single substantive opportunity appears: the Maryland Environmental Service issued a competitive sealed bid in April 2026 for supply and delivery of a mechanically cleaned wastewater screen with a 6-millimeter opening for the Dorsey Run Wastewater Treatment Plant in Jessup, Anne Arundel County, with a due date of May 28, 2026. That solicitation required shop drawings, load calculations, startup assistance, operator training, and references from five wastewater plants currently operating the proposed screen; mandatory site visits were held May 6 and May 8, 2026, and a pre-bid conference occurred May 5, 2026, via Microsoft Teams. The mismatch between the code's definition and Philadelphia's tagging of flat printing work as 23151907 suggests either a classification error in the municipality's procurement system or use of the code as a miscellaneous catch-all. Prospective vendors targeting genuine screen and sieve opportunities in state and local wastewater and water-treatment work should track Maryland Environmental Service and similar regional authorities rather than rely on this code's recent posting volume.

The geographic activity is concentrated in two jurisdictions: Philadelphia dominates with six flat printing opportunities, while Maryland Environmental Service represents the only substantive equipment procurement. No repeat buying patterns emerge beyond Philadelphia's recurring flat printing cycle. The code shows minimal relevant activity overall and does not represent a productive pursuit area for suppliers focused on screening or sieving equipment or services.
