DEF Distribution Channel & Suppliers

The On-Highway transportation industry paved the way for industrial Diesel Exhaust Fluid (DEF) by creating the manufacturing and transport infrastructure. Currently, there are many suppliers and thousands of bulk DEF dispensing locations across the United States and Canada with more being added monthly. While production and distribution of DEF are similar to on-highway, the key differences for industrial DEF users are in large volume storage and dispensing.

Cummins Distribution supports DEF needs with a broad Fleetguard® product line.  Over 40 other brands of DEF available nationally and that number is continuing to increase. Popular websites, such as and, can provide guidance on finding purchase outlets near you.
