UNSPSC 31331103: Hastalloy X bonded structural assemblies

UNSPSC 31331103 Hastalloy X bonded structural assemblies is a Commodity code that, based on recent state and local postings, shows little relevant procurement activity aligned with its nominal scope. The three most recent opportunities posted under this code—a pedestrian bridge construction project, a street and greenway infrastructure project, and a fire station facility replacement—involve structural steel, concrete, and general construction materials rather than specialized nickel-based superalloy bonded assemblies. None of the recent solicitations reference Hastalloy X or comparable high-temperature bonded structural components. The issuing bodies include Sarasota County (Florida) and the City of San Antonio (Texas) Capital Delivery Department, both pursuing infrastructure and facility construction through competitive bid and proposal formats.

Sarasota County posted IFB 262861MN on July 29, 2026 for the Midnight Pass Road Pedestrian Bridge, calling for a steel truss structure with concrete foundations and sidewalks, with responses due July 27, 2026. The City of San Antonio posted two RFCPs in June and July 2026: RFCSP2026071 for Fire Station #33 Facility Replacement (proposals due July 30, 2026, with a mandatory site visit on June 29) and RFCSP2026025 for Hays Street Bridge Connections & Eastside Area Streets (proposals due August 25, 2026, with a pre-submittal conference on July 20). All three projects are traditional construction contracts funded through bonds or general capital budgets and do not indicate procurement of specialized aerospace or high-performance alloy assemblies. The code appears to be a mislabeling or misclassification artifact in the state and local procurement taxonomy, with no documented demand for Hastalloy X components under this code in the available recent-opportunities record.
