UNSPSC 40161515: Hydraulic filters

UNSPSC 40161515 Hydraulic filters, a Commodity code, captures state and local government procurement of replacement and maintenance filters for heavy equipment and vehicle fleets, though recent solicitation activity under this code shows limited direct relevance. The actual buying under the code centers on oil, fuel, and air filters supplied to departments of transportation, public works utilities, transit agencies, and county maintenance operations. Issuing bodies include state departments of transportation, county utilities departments, city transit authorities, and municipal public works divisions. The mix reflects routine fleet maintenance operations where filters are ordered as consumable parts under annual supply contracts or as components within broader equipment maintenance agreements.

Geographic spread of recent activity includes Florida (Pinellas County Utilities), Kansas (City of Wichita), South Dakota (Department of Transportation), and Texas (City of Lubbock), with additional activity in California counties and Minnesota-coordinated cooperative purchasing. The South Dakota Department of Transportation issued IFB 26IFB19776 for automotive filters to four regional shop locations, with bids due May 8, 2026, requiring WIX cross-referencing and seven-day delivery to regional storerooms. The City of Wichita, Kansas, issued RFQ #260057 for miscellaneous air, fuel, and oil filters organized into two groups (Public Works & Utilities and Transit Department) with approved manufacturers including WIX, FRAM, AC DELCO, and BALDWIN, bids due May 1, 2026, with one-year contract plus two optional renewals. Most recent solicitations emphasize filter compatibility with manufacturer standards, obsolescence protection with full credit for excess stock, and delivery commitments tied to seven- to thirty-day windows. The code's activity is steady but fragmented across regional fleets and maintenance schedules rather than concentrated in single-agency or multi-jurisdiction cooperative vehicles.
