Ultra-Low Sulfur Diesel No. 2
A light distillate fuel oil classified as No. 2 diesel with sulfur content between 15 and 500 ppm, testing 25 degrees A.P.I. or more and Saybolt Universal viscosity under 45 seconds at 37.8°C. It falls under HTS 2710.20.10.03 due to its specific sulfur limits, API gravity, and viscosity matching the subheading for diesel fuel oils containing biodiesel. Used primarily for on-road vehicles compliant with EPA standards.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If no biodiesel content
Products without biodiesel fall under non-biodiesel petroleum oils in 2710.19, same sulfur and specs but lacking the biodiesel requirement.
If viscosity 45 seconds or more
Higher viscosity light fuel oils shift to 2710.20.20, still diesel but not meeting the <45 SUS at 37.8°C criterion.
If biodiesel exceeds basic constituent role or heavily blended
Preparations with biodiesel not primarily petroleum-based may classify as biodiesel mixtures under Chapter 38 for fuel additives.

Import Tips & Compliance
• Verify sulfur content certification via ASTM D5453 testing to confirm 15-500 ppm range for HTS 2710.20.10.03 classification
• Include biodiesel percentage documentation as it must contain biodiesel per the heading; ensure EPA fuel certification for U.S. entry
• Avoid misclassification by checking viscosity and API gravity; common pitfall is confusing with higher sulfur diesel under 2710.19
