Since 2010, diesel engine manufacturers have relied on Selective Catalytic Reduction technology (SCR) to reduce nitrous oxide emissions from exhaust gases in response to the U.S. Environmental Protection Agency’s (EPA) Clean Air Act. SCR technology injects DEF, which is composed of 32.5% automotive grade urea and 67.5% de-ionized water, into hot exhaust gas to convert poisonous gases into nitrogen and water.

Musket began producing Diesel Exhaust Fluid (DEF) in 2014 to address increasing market demand, supply redundancy concerns, and logistical optimization opportunities. Today, Musket operates 19 DEF production terminals across the United States with additional markets scheduled to open in 2021/2022. Our mission is to offer a reliable bulk wholesale DEF rack position to meet our customers' growing demand in conjunction with reducing empty mileage driven to source this product. We understand the market’s need for a quality DEF supplier with a flexible 24/7/365 operation, stable supply, product integrity and overall competitiveness. Musket DEF terminals utilize best in class QA/QC procedures, producing highest quality product meeting API and ISO 22241 standards.
