No. 6 Fuel Oil from China
No. 6 fuel oil is a heavy residual fuel oil derived from petroleum refining, with an API gravity under 25 degrees, used primarily for industrial boilers and large-scale heating systems. It falls under HTS 2710.20.05 due to its classification as a distillate and residual fuel oil testing under 25 degrees A.P.I., containing by weight 70% or more petroleum oils as the basic constituent.

Import Tips
• Verify API gravity certification through independent lab testing to confirm compliance with subheading requirements under 25 degrees
• Ensure bills of lading specify exact petroleum content (>70%) and biodiesel absence to avoid reclassification
• Comply with EPA fuel quality standards and obtain necessary import permits for environmental compliance
