Biodiesel and Renewable Diesel Definitions and Requirements
All producers, importers, wholesalers, and retailers of biodiesel, biodiesel blends, and renewable diesel blends must register their product with the Mississippi Department of Agriculture and Commerce (Department) 30 days before selling the product. All biodiesel and biodiesel blends offered for sale must be appropriately and conspicuously labeled. Blends up to 5% biodiesel (B5) must be labeled “may contain up to 5% biodiesel;” blends of B6 to B20 must identify the volume percentage of biodiesel; and blends over B20 must identify the volume percentage of biodiesel and be labeled “consult vehicle manufacturer fuel recommendations.”
Biodiesel is defined as an oxygenated fuel comprised of mono-alkyl esters of long chain fatty acids from biologically derived oil and fats. A biodiesel blend is defined as a fuel comprised of a specified ratio of biodiesel with petroleum-based fuel. Biodiesel and biodiesel blends must meet specifications set by the Department. Renewable diesel is defined as a conventional diesel fuel substitute produced from nonpetroleum renewable resources.
