Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sold for motor vehicle use
Fuel oils intended for highway vehicles may classify under motor fuel provisions.
If aromatic hydrocarbon content >50% by weight
High aromatic content shifts classification to Chapter 27 oils like benzol/toluol per subheading notes.
If biodiesel blend exceeding exclusion threshold
Fatty acid methyl ester content triggers biodiesel-specific classification outside 2710.19.
