Ultra-Low Sulfur Diesel Fuel (ULSD)
ULSD is a light distillate fuel oil refined from petroleum with a sulfur content not exceeding 15 ppm, meeting strict environmental regulations for on-road diesel engines. It tests 25 degrees A.P.I. or more and has a Saybolt Universal viscosity at 37.8°C of less than 45 seconds, classifying it under HTS 2710.19.11.11 as a light fuel oil.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sulfur content exceeds 15 ppm but ≤500 ppm
Higher sulfur levels shift classification within the same light fuel oil subheading but different sulfur band.
If for heavier residual fuel oils with viscosity ≥45 seconds
Products failing the Saybolt viscosity test at 37.8°C move to heavier fuel oil categories.
If blended with biodiesel exceeding basic oil threshold
Preparations with biodiesel or additives reducing petroleum oil content below 70% fall under biodiesel mixtures.

Import Tips & Compliance
• Verify sulfur content certification via lab testing (ASTM D5453) to confirm ≤15 ppm compliance before entry
• Include Bill of Lading specifying A.P.I. gravity and Saybolt viscosity; avoid misclassification as higher sulfur diesel
• Ensure proper storage to prevent contamination, as exceeding 15 ppm post-import can lead to penalties
