UNSPSC 31351201: Aluminum welded or brazed tube assemblies

UNSPSC 31351201 Aluminum welded or brazed tube assemblies is a Commodity code that covers raw aluminum tubing and related stock materials procured by state and local governments for infrastructure, facility operations, and manufacturing support. State and local buying under this code focuses on bulk aluminum tubing inventory—unfinished materials for in-house fabrication, repair, and construction applications rather than completed assemblies. The issuing bodies soliciting under the code include state procurement agencies (state departments of criminal justice, education, and transportation), county governments, and municipal purchasing offices. The scope of work reflects raw-material procurement rather than finished goods; the Texas Department of Criminal Justice's IFB IW257847 for raw materials–aluminum tubing, posted July 9, 2026 with a response deadline of July 24, 2026, exemplifies current purchasing activity, though detailed specifications such as gauge, alloy, diameter, wall thickness, and application are not uniformly disclosed in bid abstracts.

Geographic activity under the code concentrates in Texas, with the TDCJ solicitation and the State of Maine's RFQ 29B 26022400000000000207 (posted March 23, 2026, due April 3, 2026) for virgin aluminum substrate material for motor vehicle license plate manufacturing representing recent activity in distinct regions. The Maine RFQ specifies Alloy 3003-H12 in Gauge 20 thickness with a 70,000-pound total expected purchase quantity and calls for delivery to the State Plate Shop at Warren, Maine; bidders must submit quotations through the state's AdvantageME Vendor Self Service system on a per-pound basis. Activity appears episodic rather than continuous, with solicitations clustered around infrastructure and manufacturing-support needs; no standout repeat buyers emerge from the recent-opportunities block. The code shows sparse recent activity overall—many of the posted opportunities in the source data are mislabeled under this UNSPSC designation and pertain to unrelated construction services, building repairs, sign blanks, and educational outreach, signaling that state and local procurement data quality under the code may be inconsistent.
