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.

Import Tips

Verify API gravity via certified lab testing (ASTM D287) to confirm under 25° for this subheading; misclassification risks penalties

Include biodiesel content documentation and certificates of analysis showing >70% petroleum oils to meet basic constituent rules

Ensure proper storage and transport manifests for hazardous materials; common pitfall is inadequate spill prevention plans
