Products classified under HTS 2710.19.06.15
No. 4 Fuel Oil (High Sulfur)
A medium viscosity distillate and residual blended fuel oil with Saybolt Universal viscosity at 37.8°C between 45 and 125 seconds, testing under 25 degrees A.P.I., and containing more than 500 ppm sulfur. Classified under HTS 2710.19.06.15 due to its specific viscosity, density, and high sulfur content meeting the criteria for No. 4-type fuel oils not elsewhere specified.
Blended No. 4 Heating Oil (High Sulfur)
Blended petroleum distillate and residual oil for commercial heating, with viscosity 45-125 SUS at 37.8°C, under 25° API gravity, and sulfur exceeding 500 ppm. Fits HTS 2710.19.06.15 as a No. 4-type fuel oil preparation containing ≥70% petroleum oils with specified physical properties.
Industrial No. 4 Boiler Fuel (Sulfur >500 ppm)
Heavy distillate/residual blend for industrial boilers, featuring Saybolt viscosity 45-125 seconds at 37.8°C, API <25°, and sulfur >500 ppm. Precisely matches HTS 2710.19.06.15 for high-sulfur No. 4-type fuel oils used in stationary combustion.
High-Sulfur No. 4 Power Plant Fuel Oil
Petroleum oil blend for power generation turbines/boilers, under 25° API, 45-125 SUS viscosity at 37.8°C, sulfur >500 ppm. Classified in HTS 2710.19.06.15 as other distillate/residual fuel oils meeting No. 4-type criteria.
No. 4-Type Marine Bunker Fuel (High Sulfur)
Blended bunker-grade fuel for auxiliary marine engines, viscosity 45-125 SUS, <25° API, >500 ppm sulfur. HTS 2710.19.06.15 applies to this No. 4-type preparation ≥70% petroleum oils, excluding marine-specific distillates.
Commercial Furnace No. 4 Fuel Oil (>500 ppm S)
Distillate/residual mix for commercial furnaces, Saybolt viscosity 72 SUS average at 37.8°C, under 25° API, sulfur 800 ppm. Meets all parameters for HTS 2710.19.06.15 high-sulfur No. 4 fuel oils.
Blended Residual No. 4 Fuel for Dryers
Heavy residual-distillate blend for industrial dryers, 90 SUS viscosity, 22° API, 650 ppm sulfur. HTS 2710.19.06.15 captures this as No. 4-type fuel oil with requisite high sulfur and viscosity specs.
