UNSPSC 31351100: Ultra violet welded UV tube assemblies

UNSPSC 31351100 Ultra violet welded UV tube assemblies is a Class code that shows minimal alignment between its nominal scope and recent state and local solicitation activity. The two most recent opportunities posted under this code—both from the Colorado Department of Corrections in May 2026—actually solicit coiled aluminum alloy for license plate production, not UV tube assemblies. A third opportunity from the Superior Court of California, County of Los Angeles, seeks pallet rack wire decking, which also falls outside the code's stated product category. The mismatch suggests either tagging inconsistency at the issuing jurisdictions or a fundamental disconnect between the code's intended scope and how state and local procurement offices are currently applying it.

Activity under this code is geographically limited to Colorado and California based on recent postings, with the Colorado Department of Corrections appearing twice for identical aluminum coil requirements (350,000 pounds of 3105H21 aluminum alloy, 21-gauge thickness, for monthly delivery to the Canon City Tag Plant). Both Colorado IFBs (posted May 5 and May 19, 2026) carried response deadlines in late May, with SDVOSB preferences at 5% and freight prepaid FOB Destination terms. The Los Angeles Superior Court RFQ for 606 units of wire decking (52 inches by 42 inches, 2,500-pound load capacity) posted April 24, 2026 with a May 7 response deadline and 90-day pricing validity. Given the apparent tagging misalignment and the small number of recent postings, firms evaluating this code should verify current procurement intent with issuing bodies directly rather than relying on the nominal code definition.
