21 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.
Additional duties may apply
145 lines here reference Chapter 99, where Section 301, Section 232 and other additional duties live. Those are charged on top of the general rate and depend on where the goods were made. What those provisions are.
