UNSPSC 25171728: Exhaust brake

Devices used to restrict exhaust gas flow in the engine exhaust system in order to slow down a vehicle without utilizing the normal brakes.

UNSPSC 25171728 Exhaust brake, a Commodity code, describes aftermarket and original equipment exhaust system components and assemblies—including diesel particulate filters, oxygen sensors, temperature sensors, catalyst assemblies, and aftertreatment modules—that state and local governments procure to maintain and repair transit bus fleets, school district vehicles, and municipal equipment. State and local buyers under this code include transit authorities, municipal fleet operators, school districts, and county transportation departments that source these parts through supply agreements, firm fixed-price bids, and cooperative purchasing arrangements to keep aging and active transit and school bus fleets operational.

Recent activity clusters in the Southeast and Texas, anchored by the Metropolitan Transit Authority of Harris County (METRO) in Houston and Brevard County in Florida. METRO issued an IFB in February 2026 for approximately 448 exhaust system components across 34 line items compatible with Cummins, MCI, NABI, Nova, Orion, and New Flyer bus manufacturers, with delivery required to METRO's Central Supply Warehouse and pricing required for Year 1, Year 2, Year 3, and a three-year total; the bid closed March 11, 2026. Brevard County Purchasing Services solicited Just-in-Time inventory management services for its 1,114-asset fleet (including vehicles and equipment) with daily delivery or two-hour emergency response, requiring the contractor to manage parts supply and integrate with the County's iMaint system; Brevard's bid opening was scheduled for February 25, 2026. Additional opportunities include Rockwood School District (Missouri) seeking bus and fleet vehicle parts for 2026–2027 with sealed bids due April 9, 2026, and the School Board of Sarasota County (Florida) establishing a one-year supply agreement for automotive and light truck parts with delivery to the Transportation Garage by February 12, 2026. The code shows no standout national or multi-state repeat buyers in recent notices, and geographic concentration does not extend far beyond Texas and Florida jurisdictions in the available opportunities.
