Products classified under HTS 8412.10.00.90
Variable Specific Impulse Magnetoplasma Rocket (VASIMR) Prototype
RF plasma rocket engine prototype for future Mars missions, under HTS 8412.10.00.90 reaction engines. Magnetic nozzle plasma acceleration system. Research/development unit.
Solid Rocket Motor for Model Rockets
A small solid propellant rocket motor designed for hobbyist model rockets, classified under HTS 8412.10.00.90 as a reaction engine other than turbojets. It generates thrust through the expulsion of high-speed exhaust gases from controlled combustion of solid fuel. Falls under this code due to its reaction engine principle excluding turbojet technology.
