UNSPSC 25173711: Diesel exhaust fluid filter

A device designed to remove urea crystals and other contaminants gained during transport and storage which can cause the SCR system to malfunction or not work properly.

UNSPSC 25173711 Diesel exhaust fluid filter is a Commodity code that state and local governments procure as a component of comprehensive fleet maintenance and repair services rather than as a standalone consumable. Recent solicitations show this code embedded within broader vehicle diagnostics, air-conditioning, brake, transmission, and emission-control service contracts covering municipal, county, school district, and transit authority fleets. The work being solicited centers on labor-intensive diagnostic and repair services where DEF systems appear as one line item among many—Hillsborough County Public Schools listed DEF system services at 50 hours annually within an 83-vehicle Chevrolet fleet RFP; Charlotte Area Transit System (CATS) posted an S70 light rail vehicle conical spring spare-parts need; and Austin State Supported Living Center (Texas HHS Commission) solicited comprehensive motor-pool repair including emission-control systems. The issuing-body mix spans school districts (Hillsborough County Public Schools, Parkway School District in Missouri, Pinellas County School District), county governments (Jackson County, Missouri; Lee County and City of Fruitville, Florida), state agencies (Texas HHS Commission, Kentucky Department of Military Affairs, Illinois Department of Transportation), and transit authorities (Charlotte Area Transit System, City of Eugene, Oregon). Florida municipalities (City of Fort Myers) and Kentucky state operations appear as repeat buyers of sole-source maintenance and parts agreements for specific OEM equipment and vendor relationships.

Geographic spread concentrates in Florida (multiple sole-source notices from Fort Myers and other municipalities in August 2026), Kentucky (multiple mechanical services bids at Bluegrass Station, May through August 2026), Texas (Austin HHS, TxDOT, Texas A&M), Missouri (Jackson County, Parkway School District), and Oregon (City of Eugene Fleet Services). Representative recent opportunities include Hillsborough County Public Schools ITQ 26252-ITQDST for Chevrolet vehicles diagnostic services (responses due July 10, 2026, extended by Addendum 1), covering transmission, fuel system, EGR, DEF system, and charging services on an 83-vehicle fleet with per-hour pricing; Charlotte Area Transit System RFP 26920272144 for S70 LRV conical spring spare-parts inventory (due November 2, 2026); and Hillsborough County Public Schools RFP 26286RFPDST for school bus air-conditioning maintenance and repair with a Small Business Encouragement Program participation requirement (due August 5, 2026). The code shows limited standalone procurement activity; DEF filter demand emerges primarily as a sub-line item in larger preventive-maintenance and repair contracts where vendors bid labor rates and materials on a firm or cost-plus basis, with firm pricing FOB destination and Net 45 terms typical.
