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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If over 25° A.P.I.
Gravity threshold determines subheading within biodiesel fuel oils.
If for non-fuel chemical preparations
If repurposed as industrial chemical rather than fuel, it shifts to prepared binders.
If predominantly bituminous derivatives
Oils from bituminous minerals without biodiesel classify separately.

Import Tips & Compliance
• Conduct density tests per ASTM standards pre-shipment to confirm sub-25° A.P.I.; discrepancies lead to audits
• Provide blending ratios and origin certificates for biodiesel to trace fatty acid esters compliance
• Avoid common error of bulk packaging mislabeling; use UN-approved tanks for IMO hazardous goods

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.
Industrial Boiler Residual Fuel Oil
Residual fuel oil for industrial boilers, under 25° A.P.I. with biodiesel admixture, powers manufacturing heating. Under HTS 2710.20.05.50 for biodiesel-containing preparations >70% petroleum-based, not waste or crude. Meets chapter notes for fuel oils.
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.
