UNSPSC 23153418: Custom assembly fixtures or tooling

One-off devices built specifically for a particular production or assembly task

UNSPSC 23153418 Custom assembly fixtures or tooling, a Commodity code, covers specialized water treatment equipment and valve assemblies that state and local governments procure for municipal infrastructure projects. State and local issuers—predominantly municipal water departments and city purchasing offices—source engineered assemblies such as flow controllers paired with butterfly valves, typically pre-assembled and tested at the factory to meet potable-water specifications including AWWA compliance, NSF approval, and material standards like cast iron bodies with stainless steel liners. The City of Lubbock, Texas, for example, recently solicited an ITB for a 16-inch venturi-type flow controller with a 0-144 inches water column range and AWWA C504-compliant butterfly valve assembly to replace equipment at its North Water Treatment Plant, requiring factory assembly, testing to 0.5 percent accuracy, and compatibility with existing electric actuator mounts. These procurements are open competitive—no set-asides are evident in recent activity—and are typically awarded to the lowest responsible bidder meeting technical specifications.

Recent activity is concentrated in Texas, with the City of Lubbock posting an ITB (26-19653-YB) due May 27, 2026, for the water treatment assembly with a non-mandatory site visit scheduled for May 20, 2026. A second solicitation record from the City of Philadelphia (B2626859) for "OVA Storage," due April 24, 2026, appears misclassified under this code and shows no connection to the water treatment equipment scope. The Lubbock opportunity is representative of actual procurement under the code: the City required sealed bids submitted electronically or by hand delivery, F.O.B. delivered pricing firm for 60 days, three project references, notarized non-collusion affidavits, vendor suspension and debarment certifications, and Texas-specific compliance certifications (Iran sanctions, Israel boycott). Local vendors within Lubbock city limits qualified for a five percent price preference if their bids fell within five percent of the lowest non-resident bid, though no budget or award value was disclosed. The code shows sparse recent activity, with only one clearly relevant recent opportunity identifiable.
