No. 6 Fuel Oil
No. 6 fuel oil is a heavy residual fuel oil derived from petroleum refining, characterized by its high viscosity and API gravity under 25 degrees, making it suitable for large-scale industrial heating and power generation. It falls under HTS 2710.19.06 because it is a distillate and residual fuel oil obtained from bituminous minerals, testing under 25 degrees A.P.I., and contains over 70% petroleum oils as the basic constituent.
Bunker C Fuel Oil
Bunker C, also known as Bunker Fuel Oil, is a high-viscosity residual oil used primarily for marine bunkering and industrial furnaces, with API gravity below 25 degrees due to its heavy hydrocarbon content. Classified under HTS 2710.19.06 as a residual fuel oil from petroleum, not crude, exceeding 70% petroleum oils.
Heavy Fuel Oil (HFO) 380 cSt
HFO 380 cSt is a residual fuel oil with viscosity of 380 centistokes at 50°C, used in power plants and large boilers, featuring API gravity under 25 degrees from its bituminous mineral origins. It qualifies for HTS 2710.19.06 as a blended residual fuel oil with predominant petroleum content.
No. 6 Residual Fuel Oil
No. 6 residual fuel oil is the heaviest fraction from crude distillation, used in cement kilns and steam generators, with low API gravity under 25 degrees indicating high density. HTS 2710.19.06 covers this as a non-crude petroleum residual fuel exceeding 70% oil content.
Industrial Boiler Fuel Oil
Blended industrial boiler fuel oil combines residual and distillate stocks to achieve API under 25 degrees, optimized for stationary combustion in manufacturing. It is classified in HTS 2710.19.06 for its petroleum-dominant composition as a residual-type fuel oil.
Marine Residual Fuel Oil RMK 500
RMK 500 is a marine-grade residual fuel oil with 500 cSt viscosity, API gravity under 25 degrees, designed for auxiliary engines on cargo ships. HTS 2710.19.06 applies to this non-crude, petroleum-based heavy fuel.
