UNSPSC 31351503: Hastalloy X bolted tube assemblies

UNSPSC 31351503 Hastalloy X bolted tube assemblies is a Commodity code that captures specialized metal stock and fabricated metal components procured by state and local bodies, though recent activity under this code shows a mismatch between the nominal commodity description and actual solicitation scope. The Colorado Department of Corrections has issued two nearly identical Invitations for Bid (IFB) for coiled aluminum alloy — specifically 3105H21 aluminum in 21-gauge thickness with precise dimensional and metallurgical specifications — for use in license plate production at the Colorado Correctional Industries Tag Plant in Canon City. A third opportunity from the Superior Court of California, County of Los Angeles, solicits pallet rack wire decking, unrelated to the code's stated scope. The actual work being procured under this code identifier consists of high-tolerance aluminum coil stock meeting ASTM conversion-coating standards and load-bearing warehouse infrastructure components, not the Hastalloy tubing the code name suggests.

The Colorado Department of Corrections dominates recent activity under this code, posting two overlapping solicitations in May 2026 for 350,000 pounds of coiled aluminum on a firm, per-pound pricing basis with monthly delivery in three-truckload installments to Canon City. Both IFBs (posted May 5 and May 19, 2026, with response deadlines of May 18 and May 23, 2026) offer a five percent pricing preference to Service Disabled Veteran-Owned Small Businesses and require winning vendors to pass criminal background checks, obtain Colorado Secretary of State good standing, and carry workers' compensation and general liability insurance. The Los Angeles Superior Court opportunity, posted April 24, 2026 with a May 7 response date, requests 606 units of wire decking for warehouse storage and represents a separate, non-aluminum commodity line. Geographic activity centers on Colorado, with a secondary opportunity in California. The code shows limited recent state and local procurement volume, with activity concentrated in a single repeat buyer's manufacturing operations.
