UNSPSC 25173805: Differentials

UNSPSC 25173805 Differentials, a Commodity code, covers replacement driveline and drivetrain components—differentials, drive axles, driveshafts, and related parts—that state and local governments procure for fleet maintenance and repair. Recent solicitations show activity focused on OEM parts supply and service for heavy-duty vehicles, buses, and automotive equipment used by city departments, school districts, and county fleets. The work ranges from blanket purchase orders for as-needed parts distribution to formal competitive bids for annual supply and service contracts. Issuing bodies include city fleet operations divisions, school district transportation departments, and county purchasing offices across multiple jurisdictions.

Recent activity clusters in Texas and the upper Midwest. The City of San Antonio's Solid Waste Management Department issued an Invitation for Bids (IFB 6100019413) in May 2026 for an annual contract supplying driveline and drive axle parts and service, with sealed bids due May 1, 2026 at 2:00 p.m. Central Time and a mandatory pre-bid conference on April 22, 2026. Parkway School District in Missouri sought OEM parts and service for its bus fleet through a Request for Bid (RFB 26120) posted May 5, 2026, with bids due May 19, 2026 at 2:00 p.m. CST and an award notification target of June 11, 2026. Both solicitations require vendors to maintain adequate inventory, meet insurance and compliance standards, and quote all-inclusive F.O.B. destination pricing; neither discloses specific set-asides or award values. Opportunities under this code typically favor vendors with established relationships, fleet-service infrastructure, and the ability to source parts rapidly—often within three working days for backordered items.
