Subheadings
Products classified under HTS 8408.10.00
Cummins QSB6.7 Marine Diesel Engine
The Cummins QSB6.7 is a 6.7-liter compression-ignition inline diesel engine designed specifically for marine propulsion in workboats and pleasure craft. It features turbocharging and aftercooling for high power output up to 480 hp, with direct fuel injection for efficiency. Classified under HTS 8408.10.00 as a marine propulsion engine due to its primary function to propel vessels via inboard installation.
Volvo Penta D13-1000 Marine Propulsion Engine
Volvo Penta D13-1000 is a 12.8-liter inline-6 diesel engine delivering 1000 hp for heavy-duty marine propulsion in yachts and commercial ships. It incorporates advanced common-rail fuel injection and SCR aftertreatment for IMO Tier III compliance. Falls under HTS 8408.10.00 as a compression-ignition piston engine optimized for vessel propulsion.
MAN D2868 LE Marine Diesel Engine
The MAN D2868 LE is a V8 compression-ignition engine producing 800-1100 hp for marine propulsion in fishing vessels and ferries. It uses turbo-intercooling and electronic fuel management for reliable performance in harsh marine environments. HTS 8408.10.00 applies as it's a diesel piston engine expressly for ship propulsion.
