UNSPSC 31351704: Inconel sonic welded tube assemblies

UNSPSC 31351704 Inconel sonic welded tube assemblies is a Commodity code that covers specialized metal tube subassemblies, but the most recent state and local contract opportunities posted under it show little relevance to the code's nominal scope. The Colorado Department of Corrections issued two nearly identical Invitations for Bid in May 2026 seeking 350,000 pounds of coiled aluminum alloy (3105H21, 21-gauge) for license plate production at its Canon City facility, with monthly delivery installments of approximately 37,000 pounds per shipment on a firm, per-pound pricing basis. A third opportunity from the Superior Court of California, County of Los Angeles, solicited pallet rack wire decking—materials and products that fall outside the code's Inconel tube assembly scope. The Colorado IFBs specify coil width of 11.98 to 12.00 inches, ultimate tensile strength of 17,500 to 20,500 PSI, Bonderite M-CR 1430 C pretreatment, and ASTM B-449-Class 2 conversion coating at 35 mg./sq. ft., with coils wound on 20-inch diameter cores not exceeding 45 inches outside diameter and 1,500 pounds per coil. Both solicitations required delivery to the CCi Tag Plant in Canon City, monthly acceptance windows Monday through Thursday excluding state holidays, and a one-year contract term or until 350,000 pounds were delivered. Service Disabled Veteran-Owned Small Businesses received a 5 percent preference on pricing; vendor personnel accessing correctional facilities required CDOC background checks and PREA compliance training.

Colorado is the primary recent jurisdiction under this code, with two related IFBs posted in May 2026 by the Colorado Department of Corrections. The first IFB (IFB1CFAA20260001791) was posted May 5, 2026, with a bid due date of May 18, 2026 at 4:00 p.m. Mountain Time and a public bid opening scheduled for May 19, 2026 at 10:00 a.m. via Google Meet. The second (IFB1CFAA20260001792), posted May 19, 2026, had a due date of May 22, 2026 at 4:00 p.m. Mountain Time with bid opening on May 26, 2026. Both sought pricing through bidnetdirect.com and the Colorado Vendor Self Service portal, with estimated Intent to Award dates of May 21 and May 27, 2026, respectively. The Los Angeles Superior Court opportunity (Solicitation 202635171135), posted April 24, 2026, with a May 7, 2026 due date, appears to be miscoded and does not align with Inconel sonic welded tube assemblies. The code shows limited and largely mismatch activity in state and local procurement; businesses pursuing opportunities under this Commodity code should verify alignment with actual Inconel tube assembly specifications before investing bid preparation resources.
