Products classified under HTS 2710.19.06.25
No. 5 Heavy Fuel Oil (Bunker C Grade)
No. 5 fuel oil is a heavy residual fuel oil with a Saybolt Universal viscosity at 37.8°C exceeding 125 seconds and API gravity under 25 degrees, derived from petroleum refining processes. It is classified under HTS 2710.19.06.25 due to its specific physical properties distinguishing it from lighter distillates and other fuel oils. Primarily used in large industrial boilers and marine vessels.
No. 5 Marine Bunker Fuel Oil
Heavy fuel oil No. 5 formulated for marine propulsion, featuring high viscosity (>125 Saybolt seconds at 37.8°C) and low API gravity (<25°), obtained from bituminous mineral distillation residues. HTS 2710.19.06.25 applies specifically to this grade's properties, excluding biodiesel blends or waste oils. Supplied to oceangoing vessels for main engines.
Industrial No. 5 Residual Fuel Oil
Residual fuel oil No. 5 for stationary industrial combustion, characterized by API gravity under 25° and Saybolt viscosity over 125 seconds at 37.8°C, containing over 70% petroleum oils. This classification under 2710.19.06.25 reflects its heavy, undistilled nature from refinery processes. Ideal for power plants and large furnaces.
No. 5 High Sulfur Fuel Oil
No. 5 grade heavy fuel oil with sulfur content typically 1-3.5%, API <25°, and viscosity >125 Saybolt seconds at 37.8°C, a residual product from petroleum refining. Falls under HTS 2710.19.06.25 for heavy fuel oils meeting these specs, distinct from low-sulfur or biodiesel preparations. Used in permitted industrial burners.
Blended No. 5 Fuel Oil for Boilers
Blended residual fuel oil meeting No. 5 specifications: API gravity under 25 degrees, Saybolt Universal viscosity >125 seconds at 37.8°C, with ≥70% petroleum oils as basic constituent. HTS 2710.19.06.25 covers such blended heavy fuels excluding waste or biodiesel. Optimized for large-scale boiler systems.
