N.D. Cent. Code § 23.1-13-06

A dealer may not sell at retail alternative fuel unless the dispensing unit and price advertising contains the name and main components of the alternative fuel or alternative fuel blend. The disclosure must follow the same labeling specifications that apply for petroleum-based fuels. The department shall adopt rules under chapter 28-32 for labeling of petroleum products and alternative fuels. A producer of alternative fuels or alternative fuel blends may provide a retailer with a label promoting the benefits of the alternative fuel if the label meets the requirements of this section.
