Products classified under HTS 2710.19.11.25
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 2710.19.11.25 due to its specific gravity, viscosity, and sulfur content meeting the criteria for No. 4-type fuel oils used in industrial heating.
Blended No. 4 Heating Oil (High Sulfur)
A blended distillate fuel oil for commercial heating systems, consisting of >70% petroleum oils with API ≥25°, viscosity 45-125 SUS at 37.8°C, and sulfur >500 ppm. Fits HTS 2710.19.11.25 as a residual/distillate blend designed for medium boilers and industrial furnaces.
Industrial No. 4-Type Fuel Oil (>500 ppm S)
Petroleum distillate fuel for industrial burners and generators, with Saybolt viscosity 65 SUS average, API 28°, exceeding 500 ppm sulfur content. HTS 2710.19.11.25 applies precisely to this No. 4 specification for non-road heavy equipment and factory heating.
High-Sulfur Bunker Grade No. 4 Fuel
A No. 4 specification bunker fuel for marine auxiliary engines and port generators, featuring >500 ppm sulfur, 25-30 API, and 90 SUS viscosity at 100°F. Meets HTS 2710.19.11.25 for distillate/residual fuels used in stationary marine applications.
No. 4 Diesel Blend Fuel Oil (High Sulfur)
Blended fuel oil combining diesel distillates and residuals to achieve No. 4 specs: API >25°, 45-125 SUS viscosity, sulfur >500 ppm, for off-highway diesel engines. HTS 2710.19.11.25 covers this as distillate fuel oil for heavy machinery.
Commercial Boiler No. 4 Fuel Oil (>500 ppm S)
Distillate fuel oil formulated for multi-burner commercial boilers, with precise 50-100 SUS viscosity, 27 API gravity, and sulfur content over 500 ppm. Precisely matches HTS 2710.19.11.25 for No. 4-type residual fuels in heating applications.
