Chemicals are classified into three schedules based on their potential for weaponization and legitimate uses:
Schedule 1: These chemicals have few, if any, legitimate uses outside of chemical weapons. Examples include nerve agents like sarin and VX. Schedule 2: These chemicals have some legitimate uses but can also be used to make chemical weapons. Examples include certain pesticides. Schedule 3: These chemicals have large-scale industrial applications but can still be used to produce chemical weapons. Examples include phosgene and hydrogen cyanide.
