Products classified under HTS 2710.19.06.30
Bunker C Fuel Oil
Bunker C is a heavy residual fuel oil classified as Fuel Oil No. 6 under HTS 2710.19.06.30 due to its API gravity under 25 degrees and Saybolt Universal viscosity exceeding 125 seconds at 37.8°C. It is primarily used as marine bunker fuel for large oceangoing vessels.
No. 6 Residual Fuel Oil
Standard No. 6 fuel oil is a high-viscosity residual product from crude oil distillation, meeting HTS 2710.19.06.30 specs with Saybolt viscosity >125 seconds and low API gravity. Used in industrial boilers and power generation.
Heavy Fuel Oil 380 cSt
IFO 380 (Intermediate Fuel Oil with 380 centistokes viscosity at 50°C) qualifies as Fuel Oil No. 6 under HTS 2710.19.06.30 when meeting the Saybolt viscosity >125 sec at 37.8°C and sub-25° API criteria. Common in international shipping bunkers.
Industrial Boiler Fuel Oil No. 6
Heavy residual fuel oil No. 6 formulated for large industrial boilers, classified under HTS 2710.19.06.30 for its high viscosity (>125 SUS at 37.8°C) and density (API <25°). Provides high BTU content for manufacturing processes.
Power Plant Residual Fuel Oil
No. 6 fuel oil specification for utility-scale power generation, meeting HTS 2710.19.06.30 with required low API gravity and high Saybolt viscosity. Economical baseload fuel for coal-alternative combustion.
