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.
