Para-snowboarding classification is the classification system for para-snowboarding. The sport originally called Adaptive Snowboard is now practiced by hundreds of athletes around the world. The International Paralympic Committee (IPC) defines two classes:SB-LL for athletes with a physical impairment affecting one or both legs, and SB-UL for athletes with a physical impairment affecting one or both arms who compete standing. The sport made its official Winter Paralympic debut in the 2014 Winter Paralympics in Sochi, Russia.
