UNSPSC 31351401: Aluminum bonded tube assemblies

UNSPSC 31351401 Aluminum bonded tube assemblies is a Commodity code. State and local governments purchase raw aluminum tubing and related aluminum materials through this code, though recent solicitations show minimal direct specification of bonded assemblies per se. The Texas Department of Criminal Justice posted an IFB for raw materials-aluminum tubing (due July 24, 2026) that does not specify gauge, alloy, diameter, wall thickness, or application. The State of Maine Department of Administrative and Financial Services sought quotations for virgin aluminum substrate material in Alloy 3003-H12 specification (Gauge 20 thickness with chromate conversion coating) for manufacturing motor vehicle license plates, with a 70,000-pound purchase quantity and April 3, 2026 deadline. Issuing bodies include state agencies, departments of criminal justice, departments of motor vehicles, and state procurement offices seeking raw material feedstock for manufacturing or maintenance operations. The code sees activity from industrial and operational state agencies rather than counties, cities, school districts, or transit authorities.

Recent activity concentrates in Texas and Maine, with a single Texas Education Agency procurement tagged to this code showing a mixed scope unrelated to aluminum tubing. The Texas Department of Criminal Justice IFB for aluminum tubing (Solicitation IW257847, due July 24, 2026) represents the most recent direct application of this code, though no detailed specifications or quantities are available in the solicitation summary. The Maine RFQ #29B 26022400000000000207 (due April 3, 2026) for 70,000 pounds of Alloy 3003-H12 aluminum coil stock with Alodine chromate conversion coating demonstrates state procurement for aluminum materials at scale. The code shows low overall activity frequency among state and local issuers, suggesting either narrow demand or misalignment between the code's nominal scope and how jurisdictions actually classify aluminum material procurements.
