About

The National Biodiesel Accreditation Commission oversees a cooperative and voluntary program for the accreditation of producers and marketers of biodiesel fuel called BQ-9000®. The program is a unique combination of the ASTM standard for biodiesel, ASTM D6751, and a quality systems program that includes storage, sampling, testing, blending, shipping, distribution, and fuel management practices.

BQ-9000® is open to any biodiesel manufacturer, marketer, distributor, or laboratory handling biodiesel and biodiesel blends in the United States and Canada.
