UNSPSC 31162403: Hinges

UNSPSC 31162403 Hinges is a Commodity code that covers specialized hinges and bearing components used in municipal infrastructure, including revenue vault hinge bearing rebuilds and hangar door hinges for aircraft facilities. State and local governments procure hinges as repair and replacement components in construction, maintenance, and capital projects affecting public buildings, transportation facilities, and revenue-generating infrastructure. Issuing bodies include city purchasing departments, county facilities and public works offices, and airport authorities, typically soliciting through RFQ and IFB notices for micro purchases and construction-integrated procurements.

Recent activity shows sparse direct solicitation under this code. The City of Philadelphia posted an RFQ for revenue vault hinge bearing rebuild services (Solicitation B2627299, due June 5, 2026) as a micro purchase not exceeding $43,000. Collier County, Florida issued two IFB notices for Everglades Airpark Hangar Repairs (Solicitations 258614 and 258614R, due March 30 and April 23, 2026, respectively) that included replacement of eight bifold hangar doors with integral hinges as a component within a broader $1.2 million construction scope. A Sourcewell cooperative purchasing RFP for Law Enforcement Equipment (RFP 061626, due June 16, 2026) involved multiple Washington counties but does not appear hinge-related. Geographic activity centers on Florida and Pennsylvania based on recent postings, with multistate cooperative purchasing frameworks also active. The code shows low transaction volume relative to broader construction and facilities maintenance categories; hinges typically appear as line items within larger construction solicitations rather than standalone commodity purchases.
