UNSPSC 25173721: Exhaust heat shields and guard grids

Specific heat shields and guard grids used in engines and vehicles to prevent direct contact to high heat sources.

UNSPSC 25173721 Exhaust heat shields and guard grids is a Commodity code that addresses exhaust system components and protective equipment for vehicle fleets. State and local governments buy exhaust parts—diesel particulate filters, oxygen sensors, temperature sensors, catalyst assemblies, and aftertreatment modules—primarily to maintain and repair transit bus fleets, school district vehicles, and county fleet assets. The code sees activity across county purchasing departments, transit authorities, and school districts soliciting both individual component replacement and broader vehicle parts supply contracts. Issuing bodies span state cooperative purchasing vehicles (Sourcewell), individual municipalities, transit authorities, and school districts that manage fleets ranging from light-duty vehicles to heavy-duty transit buses.

Recent solicitations ground the actual scope: the Metropolitan Transit Authority of Harris County, Texas (METRO) issued an Invitation for Bids in February 2026 for exhaust parts including diesel particulate filters, oxygen sensors, temperature sensors, and catalyst assemblies for transit buses, with delivery required to the Central Supply Warehouse and bids due March 11, 2026. Rockwood School District in Missouri solicited sealed bids for bus and fleet vehicle parts for fiscal year 2026-2027 through April 9, 2026, encompassing aftermarket and OEM parts for school buses and light-duty vehicles. Brevard County, Florida issued a bid for just-in-time inventory management services for automotive parts and equipment supplies to maintain 1,114 fleet assets with bids due February 25, 2026. Activity concentrates in Texas (METRO), Florida (Brevard County, Sarasota County Schools), Missouri (Rockwood School District), and Georgia (City of Atlanta heavy-duty trailers and parts procurement announced March 4, 2026), with secondary activity across Illinois, Arizona, New York, and other states through Sourcewell cooperative purchasing agreements. The code shows consistent demand tied to fleet maintenance cycles rather than episodic procurement.
