Products classified under HTS 8412.10.00
Cold Gas Thruster
A cold gas thruster stores compressed nitrogen or helium gas released through a valve and nozzle to produce reaction thrust for small spacecraft maneuvers. Under HTS 8412.10.00 as a non-combustion reaction engine relying on pressurized gas expulsion.
Pulsed Plasma Thruster
A pulsed plasma thruster uses electrical discharge to vaporize solid Teflon propellant into plasma accelerated electromagnetically for deep space propulsion. HTS 8412.10.00 covers this electromagnetic reaction engine producing thrust via plasma expulsion.
Hybrid Rocket Engine
A hybrid rocket engine employs solid fuel with liquid oxidizer, burning to produce gaseous reaction products expelled for thrust in sounding rockets. Falls under HTS 8412.10.00 as chemical reaction engine other than turbojets.
Monopropellant Thruster
A monopropellant thruster decomposes hydrazine over iridium catalyst to produce reaction gases for spacecraft attitude control. Classified HTS 8412.10.00 for its catalytic reaction thrust generation mechanism.
Bipropellant Liquid Rocket Engine
A bipropellant liquid rocket engine uses separate fuel and oxidizer propellants, such as RP-1 and liquid oxygen, to generate thrust through chemical reaction in a combustion chamber. It falls under HTS 8412.10.00 as a reaction engine other than turbojets, specifically designed for spacecraft propulsion where reaction mass is expelled at high velocity.
Solid Rocket Motor
A solid rocket motor contains pre-mixed solid propellant like ammonium perchlorate composite that burns to produce hot gases expelled through a nozzle for thrust. Classified under HTS 8412.10.00 as it operates by reaction principles distinct from turbojet cycles, commonly used in missile boosters and launch vehicles.
Hall Effect Thruster
An electric Hall effect thruster ionizes xenon propellant using a radial magnetic field and expels ions via electric acceleration for spacecraft station-keeping. It qualifies under HTS 8412.10.00 as a reaction engine producing thrust by reaction mass expulsion, excluding turbojets.
