UNSPSC 31281500: Stamped components

UNSPSC 31281500 Stamped components is a Class code under which state and local governments procure repair, maintenance, and replacement services for engine and chassis components in transit fleets and specialized equipment, rather than purchasing stamped metal parts as discrete commodities. Recent solicitations show heavy emphasis on heavy-duty engine repair — particularly Cummins CNG and diesel engines used in bus fleets — and associated drivetrain and chassis system maintenance. Work includes engine rebuilds, dyno testing, transmission and axle repairs, brake and suspension service, and as-needed maintenance performed either at contractor facilities or at customer sites, with most contracts requiring federal compliance (Buy America, Davis-Bacon, FTA certifications) alongside state and local licensing and insurance requirements.

The issuing bodies are transit authorities and county transportation departments rather than municipal procurement offices or school districts; the Orange County Transportation Authority, Broward County Transportation Department, and State of Nevada Department of Administration are the primary recent buyers shown. Geographic activity centers on California, Florida, and Nevada based on the three most recent opportunities posted between May and September 2026. The Orange County Transportation Authority issued an RFQ for non-warranty Cummins CNG engine repair services (RFQ 260538, due September 17, 2026, $20,000 one-year lump-sum) requiring Cummins-certified repair facilities with authorization to service multiple ISL-G and L9N engine models. Broward County Transportation Department posted an open-end indefinite-quantity contract (TRN2132053B1, due June 1, 2026) for comprehensive Cummins engine rebuilds and multi-system chassis repairs on bus models from 2009–2022, with 24-hour response requirements and five-year warranties on rebuilt engines. The State of Nevada Department of Administration solicited bids for a new SD28-3 #652 Locomotive (10TCAS4014, due October 6, 2026) with Nevada-business and veteran-owned-business price preferences applied and a requirement for new equipment only.
