Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended specifically for U.S. government vessels
Government-spec heavy bunker fuels have dedicated subheadings.
If lighter marine distillates
Distillate marine fuels with higher distillation points classify as light oils.
If crude oil topping refinery streams
Certain unfinished refinery products remain under crude petroleum headings.
