Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If non-biodiesel version
Absence of biodiesel mono-alkyl esters moves it to standard fuel oil codes.
If aromatic hydrocarbon mix
If >50% aromatics like xylol, reclassifies under coal tar distillates.

No. 6 Fuel Oil
No. 6 fuel oil is a heavy residual fuel oil derived from petroleum refining, testing under 25 degrees A.P.I., used primarily for industrial boilers and large-scale heating systems. It falls under HTS 2710.20.05.50 as a distillate and residual fuel oil containing biodiesel blends with the specified gravity, not classified as crude or waste. This classification applies to fuel oils where petroleum oils exceed 70% by weight as the basic constituent.
Bunker C Fuel Oil
Bunker C is a high-viscosity residual fuel oil from petroleum, under 25° A.P.I., blended with biodiesel for marine and power generation use. Classified in HTS 2710.20.05.50 due to its heavy gravity and biodiesel inclusion in preparations where petroleum exceeds 70% by weight. It's distinct from lighter fuels or crude oils.
Heavy Fuel Oil (HFO) Biodiesel Blend
Heavy Fuel Oil blended with biodiesel, testing under 25° A.P.I., serves as a low-cost energy source for ships and factories. HTS 2710.20.05.50 covers this as a residual fuel oil preparation with >70% petroleum oils and biodiesel, excluding waste or crude. Its density distinguishes it from lighter distillates.
Power Plant Grade No. 6 Oil
No. 6 oil customized for power plants, heavy gravity under 25° A.P.I., with biodiesel for emissions compliance. HTS 2710.20.05.50 applies to such blended residual fuels where petroleum oils dominate. Used in electricity generation, not lighter fuels.
