No. 2 Diesel Fuel Oil (High Sulfur)
A middle distillate petroleum oil used primarily as fuel for diesel engines in trucks, buses, and off-road equipment, testing 25 degrees A.P.I. or more with Saybolt Universal viscosity at 37.8°C less than 45 seconds. It contains more than 500 ppm sulfur, distinguishing it from ultra-low sulfur diesel, and falls under HTS 2710.20.10.04 as a light fuel oil No. 2 classified as diesel. This classification applies to non-road and locomotive use where higher sulfur content is permitted.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing no biodiesel
Absence of biodiesel shifts classification to motor fuel oils under 2710.19, excluding biodiesel-containing preparations.
If sulfur ≤500 ppm
Lower sulfur content (ultra-low sulfur diesel) falls under separate subheading for fuels meeting EPA on-road standards.
If 90%+ distills at 210°C (light oils)
Meets light oil definition per subheading note, reclassifying from fuel oil to petroleum distillates based on ISO 3405 distillation.

Import Tips & Compliance
• Verify sulfur content via ASTM D5453 testing exceeds 500 ppm and document with certificates for CBP compliance
• Ensure product meets 25° API gravity and <45 SUS viscosity at 37.8°C; provide lab reports to prevent reclassification as crude or other fuels
