Products classified under HTS 8412.90.10.00
Hydrojet Impeller for Marine Propulsion
A precision-engineered impeller designed specifically for hydrojet engines used in marine propulsion systems, such as personal watercraft and high-speed boats. It falls under HTS 8412.90.10.00 as a core part of hydrojet engines that generate thrust by accelerating water through a jet nozzle. This classification is distinct from general marine engine parts due to its specialized role in water-jet technology.
Stator Assembly for Hydrojet Engine
The stator assembly in a hydrojet marine propulsion engine directs water flow to optimize impeller efficiency and thrust. Classified under HTS 8412.90.10.00 because it is an integral part of the hydrojet engine core, essential for propulsion in watercraft like jet skis and patrol boats. It differs from general pump stators by its marine propulsion-specific design.
Nozzle Diffuser for Marine Hydrojet
A reverse-thrust capable nozzle diffuser that controls water exit velocity in hydrojet propulsion systems for boats. It is classified under HTS 8412.90.10.00 as a dedicated part of hydrojet engines for marine use, enabling steering and braking functions. This is separate from nozzle parts in aircraft or general fluid machinery.
Hydrojet Pump Housing for Jet Boats
Durable pump housing that encases the impeller and stator in hydrojet engines for marine propulsion on jet boats. Falls under HTS 8412.90.10.00 due to its role in containing high-pressure water flow for thrust generation in watercraft. Distinct from housings in land-based pumps or combustion engines.
Thrust Bearing for Hydrojet Propulsion
High-load thrust bearing supporting axial forces in hydrojet engines for marine applications like fireboats. Classified in HTS 8412.90.10.00 as it is engineered for the extreme water pressures of propulsion jets. Not a general bearing due to marine hydrojet tolerances.
Hydrojet Intake Grille for Watercraft
Stainless steel intake grille preventing debris entry into hydrojet propulsion engines on personal watercraft. Under HTS 8412.90.10.00 for its integral role in marine hydrojet water intake systems. Differs from hull grilles by direct engine integration.
