Ultra-Low Sulfur Diesel Fuel No. 2
This is a refined petroleum 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 having Saybolt Universal viscosity at 37.8°C of less than 45 seconds. It meets the specifications for light fuel oils used primarily in on-road diesel engines and falls under HTS 2710.19.11.03 due to its precise sulfur limits and physical properties distinguishing it from crude or higher sulfur fuels.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sulfur exceeds 500 ppm but not more than 2000 ppm
Higher sulfur content shifts classification within the same diesel oil subheading to reflect environmental and regulatory distinctions.
If Saybolt Universal viscosity at 37.8°C is 45 seconds or more
Products with higher viscosity are classified separately as heavier fuel oils, even if sulfur and A.P.I. match.
If containing biodiesel or other additives making petroleum oils less than 70% by weight
Preparations with significant non-petroleum additives like biodiesel fall under Chapter 38 as biodiesel blends rather than pure petroleum oils.

Import Tips & Compliance
• Verify sulfur content via ISO 20846 or ASTM D5453 testing to confirm compliance with 15-500 ppm limit; non-compliance risks reclassification or penalties
• Include detailed certificates of analysis showing A.P.I. gravity, viscosity, and sulfur levels in entry documentation for CBP review
• Avoid common pitfalls like mislabeling as crude oil; ensure bills of lading specify refined distillate status
