HTS heading 2401

Unmanufactured tobacco (whether or not threshed or similarly processed); tobacco refuse — 165 codes under this heading, with the duty on each.

124 of these lines state no rate of their own and inherit one from the line above, which is how the schedule is read. Each says which line it came from.
