UNSPSC 73151501: Assembly line work

UNSPSC 73151501 Assembly line work (Commodity) covers factory-assembled equipment subassemblies supplied by vendors for integration into municipal infrastructure, as demonstrated by recent state and local solicitations. The code encompasses pre-assembled, tested, and validated component packages where the supplier performs factory-level fabrication, assembly, and quality control before delivery to the buying jurisdiction. State and local buyers use this code primarily for water and wastewater treatment equipment—specifically control valves, flow measurement devices, and related actuator-compatible subassemblies that arrive ready for installation by the public entity's staff. Issuing bodies include municipal utilities and water authorities. The City of Lubbock, Texas has been the principal recent buyer under this code, soliciting factory-assembled potable water treatment components meeting AWWA and ASTM material and performance standards.

The City of Lubbock, Texas dominates recent activity under this code. Lubbock issued ITB 26-19653-YB (posted May 12, 2026, with sealed bids due May 27, 2026) for a replacement rate of flow controller and 16-inch butterfly valve assembly for the North Water Treatment Plant, specifying factory assembly and testing to 0.5 percent accuracy, cast iron ASTM A536 Grade 65-45-12 body construction, Type 316 stainless steel components, NSF 61 epoxy coating for potable water service, and compatibility with existing electric valve actuators. The solicitation required bidders to fit all equipment within 46.5 inches maximum space and provide operation and maintenance manuals; a non-mandatory site visit was held May 20, 2026. Sealed bids were submitted through Lubbock's Bonfire electronic portal or by hand delivery, with firm pricing required for sixty days on an F.O.B. delivered basis. The City applied a local preference of up to five percent for bidders with principal place of business within city limits on contracts under $500,000. Texas activity represents the entirety of visible recent procurement under this code; no additional geographic spread or multi-state activity is evident in the current opportunities block.
