UNSPSC 23153400: Assembly machines

UNSPSC 23153400 Assembly machines, a Class code, covers the procurement of specialized water treatment equipment assemblies — specifically venturi-type flow controllers and butterfly valves designed for potable water systems. State and local governments use this code to acquire factory-assembled, tested measurement and control equipment that integrates multiple components into a single operational unit for municipal water treatment plants. The issuing bodies soliciting under the code include municipal water utilities and city purchasing departments. The City of Lubbock, Texas has posted competitive procurement activity under this code for replacement equipment at its North Water Treatment Plant, indicating active demand from municipal water infrastructure operators.

Recent activity concentrates in Texas, where the City of Lubbock issued ITB 26-19653-YB in May 2026 for a replacement rate of flow controller and 16-inch butterfly valve assembly. The solicitation required factory assembly and testing to 0.5 percent accuracy within a 46.5-inch spatial envelope, with components including a cast iron ASTM A536 Grade 65-45-12 body, Type 316 stainless steel throat liner, AWWA C504 compliance, and NSF 61 epoxy coating suitable for potable water. Sealed bids were due May 27, 2026, with a non-mandatory site visit held May 20, 2026. The City reserved the right to extend contract terms through interlocal purchasing agreements to Frenship Independent School District, Lubbock County, Lubbock Independent School District, and Texas Tech University. Vendors must submit three project references, complete suspension and debarment certifications, comply with Texas Iran sanctions and Israel boycott provisions, and acknowledge all addenda. The City applies a local preference allowing bids within five percent of the lowest non-resident bid to receive award consideration if local economic development value is demonstrated, though this preference applies only to contracts under $500,000. No budget or award value was specified in the procurement documents.
