Products classified under HTS 2710.19.11.15
Blended No. 4-Type Boiler Fuel Ultra Low S
Blended distillate and residual petroleum oils forming No. 4 fuel with 25+° A.P.I., 45-125 seconds SUS at 37.8°C, ≤500 ppm sulfur for emission compliance. HTS 2710.19.11.15 applies as it meets exact viscosity and sulfur limits for this subheading. Essential for large-scale boiler operations in utilities.
Power Plant No. 4 Distillate Fuel Low S
Distillate-heavy No. 4 fuel oil for power generation turbines, with A.P.I. ≥25°, viscosity 45-125 SUS at 37.8°C, sulfur ≤500 ppm. HTS 2710.19.11.15 due to matching subheading for low-sulfur No. 4-type oils. Optimized for peaking plants and backup generators.
No. 4 Fuel Oil Ultra-Low Sulfur
A medium-viscosity distillate fuel oil derived from petroleum refining, testing 25 degrees A.P.I. or more with Saybolt Universal viscosity at 37.8°C between 45 and 125 seconds, containing ≤500 ppm sulfur. Classified under HTS 2710.19.11.15 due to its specifications as a No. 4-type fuel oil for industrial heating and power generation. Used primarily in boilers and large burners where low sulfur reduces emissions.
Industrial No. 4 Heating Oil Low Sulfur
Petroleum-based No. 4 fuel oil for commercial heating systems, with ≥25° A.P.I., 45-125 SUS viscosity at 37.8°C, and sulfur ≤500 ppm. Falls under HTS 2710.19.11.15 as a distillate/residual blended fuel oil not elsewhere specified, excluding biodiesel or waste. Commonly used in manufacturing plants and district heating.
Marine No. 4 Fuel Oil Low Sulfur Compliant
Low-sulfur No. 4 petroleum fuel oil for auxiliary marine engines, ≥25° A.P.I., 45-125 SUS viscosity, ≤500 ppm S to meet harbor regulations. Classified in HTS 2710.19.11.15 for its precise fuel oil parameters excluding biodiesel. Used in inland waterway vessels and port operations.
