Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If higher viscosity HFO 500+ grades
Subheadings differentiate by viscosity bands within heavy fuel oils.
If 90%+ distills at 210°C (light oils)
Light oil preparations per subheading note exclude from heavy fuel classification.
If sold as petroleum additive rather than base fuel
Non-fuel preparations like additives classify under separate petroleum headings.

Import Tips & Compliance
• Submit ISO 8217 specification sheets proving viscosity and API compliance
• Declare exact barrel volume (158.98L at 15.6°C) per US note for accurate quantity reporting
• Watch for contamination risks that could reclassify as waste oils under 2710.91
