Products classified under HTS 2710.19.06.05
No. 4 Fuel Oil Ultra-Low Sulfur
A heavy distillate fuel oil classified under HTS 2710.19.06.05 due to its API gravity under 25 degrees, Saybolt Universal viscosity between 45 and 125 seconds at 37.8°C, and sulfur content not exceeding 500 ppm. It is primarily used for industrial boilers and marine applications where low-emission fuels are required. This specification meets stringent environmental regulations for reduced sulfur emissions.
Marine No. 4-Type Fuel Oil Low Sulfur
Blended No. 4-type residual fuel oil for marine bunker use, with sulfur ≤500 ppm, viscosity 45-125 SUS at 37.8°C, and API <25°. Meets IMO low-sulfur standards under HTS 2710.19.06.05 for distillate/residual blends. Used in auxiliary engines on vessels requiring compliant heavy fuels.
Industrial Boiler No. 4 Fuel Oil 500 ppm S
Heavy fuel oil for stationary industrial boilers, specified as No. 4-type with ≤500 ppm sulfur, API under 25°, and 45-125 seconds Saybolt viscosity at 37.8°C per HTS 2710.19.06.05. Designed for high-efficiency combustion in manufacturing facilities complying with EPA sulfur limits.
Blended Residual No. 4 Fuel Oil Low S
A blend of distillate and residual oils forming No. 4 fuel with sulfur ≤500 ppm, <25° API, and viscosity 45-125 SUS, imported under HTS 2710.19.06.05. Suitable for older burners in commercial heating systems requiring ultra-low sulfur heavy fuel.
Power Plant No. 4 Type Fuel Oil ULS
Ultra-low sulfur (≤500 ppm) No. 4 fuel oil for backup generators in power plants, with Saybolt viscosity 45-125 sec at 37.8°C and API <25°, per HTS 2710.19.06.05 specs. Provides reliable heavy fuel for peak shaving operations.
Commercial Heating No. 4 Fuel 0.05% S
No. 4-type fuel oil with max 0.05% (500 ppm) sulfur for commercial building heating systems, API under 25°, 45-125 SUS viscosity, classified HTS 2710.19.06.05. Meets urban air quality standards for multi-burner installations.
