Certified Firewood Producers in Minnesota

What MDA Certified Means

​MDA firewood producers are certified for selling firewood based on treatment standards set by both the Minnesota Department of Agriculture and the United States Department of Agriculture.

MDA Heat Treatment Certified means the company operates a kiln that has passed a rigorous inspection and testing process and has successfully demonstrated the ability to heat their firewood to a minimum core temperature of 140˚F for 60 minutes.

MDA Kiln Dry Certified means the company operates a kiln that has passed an inspection and testing process and has successfully demonstrated the ability to heat their firewood to a specified temperature and final moisture content, dependent on the size of their firewood pieces. This certification is limited to wood that has a maximum thickness of three inches, and thus is primarily used for lumber, but may also be used for firewood kindling of the appropriate size.
