Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pure petroleum without biodiesel
Biodiesel absence moves to 2710.19 distillate fuels
If viscosity <45 SUS
Lower viscosity No. 2-type fuels classify in preceding subheading
If for chemical/feedstock use, not fuel
Non-fuel preparations containing biodiesel shift to Chapter 38
