Products classified under HTS 2710.20.10.25
No. 4 Fuel Oil (High Sulfur)
A medium-weight distillate fuel oil derived from petroleum refining, testing 25 degrees A.P.I. or more with Saybolt Universal viscosity between 45-125 seconds at 37.8°C, containing over 500 ppm sulfur. Classified under HTS 2710.20.1025 due to its fuel oil specifications and high sulfur content in biodiesel-blended preparations with 70%+ petroleum oils. Used primarily for industrial heating and marine applications.
Blended No. 4 Marine Bunker Fuel (High Sulfur)
A biodiesel-blended No. 4-type residual fuel oil for marine bunkering, with API gravity ≥25°, viscosity 45-125 SUS at 37.8°C, and sulfur >500 ppm. Fits HTS 2710.20.1025 as a preparation with ≥70% petroleum oils containing biodiesel, designed for ship auxiliary engines outside low-sulfur emission zones.
Industrial Boiler No. 4 Fuel Oil (Sulfur >500 ppm)
Heavy distillate fuel oil blended with biodiesel for stationary industrial boilers, exhibiting 25°+ API gravity, 45-125 SUS viscosity, and exceeding 500 ppm sulfur. HTS 2710.20.1025 applies to this preparation where petroleum oils form ≥70% by weight as the basic component.
High-Sulfur Biodiesel Blend No. 4 Heating Oil
A No. 4-grade heating oil preparation containing biodiesel and >70% petroleum distillates, with sulfur >500 ppm, API ≥25°, and viscosity 45-125 seconds SUS. Classified in HTS 2710.20.1025 for its fuel oil characteristics and high sulfur in non-retail bulk form.
No. 4 Generator Fuel Oil (High Sulfur Content)
Distillate fuel oil for diesel generators, biodiesel-blended with ≥70% petroleum oils, >500 ppm sulfur, 25+° API, and 45-125 SUS viscosity at 37.8°C. Meets HTS 2710.20.1025 criteria for high-sulfur No. 4-type fuel oils containing biodiesel.
