UNSPSC 31351701: Aluminum sonic welded tube assemblies

UNSPSC 31351701 Aluminum sonic welded tube assemblies is a Commodity code that encompasses raw aluminum tubing and aluminum sheet materials used across diverse state and local operations. Recent solicitations reveal minimal activity specifically aligned with the code's nominal scope of sonic-welded tube assemblies; instead, the recent opportunities tagged to this code request raw aluminum materials in various forms—coiled aluminum for license plate production, aluminum sign blanks, sheet stock, and unfinished tubing. The Texas Department of Criminal Justice issued an IFB on July 9, 2026 (due July 24, 2026) for raw materials–aluminum tubing without specification detail on gauge, alloy, diameter, wall thickness, or application. The State of Maine Department of Administrative and Financial Services, on behalf of the Bureau of Motor Vehicles, sought quotations for virgin aluminum substrate in Alloy 3003-H12 coiled rolls on March 23, 2026 (due April 3, 2026) for reflectorized license plate manufacturing, requiring 70,000 pounds total. Orange County, Florida solicited sealed bids for aluminum sign blanks across 45 line items on April 21, 2026 (due April 30, 2026) under a five-year requirements contract, specifying Aluminum Association specifications 5052H38 for anodized aluminum in various signage configurations.

State departments, counties, and municipal utilities drive activity under this code. The mix includes the Texas Department of Criminal Justice, the State of Maine Bureau of Motor Vehicles, Orange County Public Works (Florida), and municipal procurement offices across multiple states. Geographic concentration is limited; recent activity appears in Texas, Maine, and Florida, with scattered instances elsewhere. The code does not show sustained solicitation for fabricated sonic-welded assemblies; instead, issuing bodies procure unfinished aluminum materials and commodity-form stock. A business development professional should note the mismatch between the code's nominal scope and current buying patterns—opportunities reflect raw-material sourcing rather than engineered tube assembly work.
