Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If biodiesel-dominant blend
If biodiesel >30% or primary constituent, moves to biodiesel fuels in 3826.
If straight petroleum diesel
No biodiesel shifts to non-biodiesel low-sulfur diesel.
If higher sulfur >500 ppm
Exceeding 500 ppm sulfur places it in higher sulfur fuel oil subheadings.

Import Tips & Compliance
• Certify B20 stability and cold filter plugging point for winter imports
• Declare exact sulfur via independent lab (e.g
• ISO 20884); retain for CBP review
• Avoid bulk imports without sulfur guarantee; contamination risks reclassification
