It depends on the density of the shipment. The denser the shipment, the lower the class. Here is a list of classes:

<12 lbs per cu. ft. = class 100. nmfc = 112870-1

12 to <30 lbs per cu. ft. = class 70. nmfc = 112870-2

30 or more lbs per cu. ft. = 55. nmfc = 112870-3

If you Google 'shipment density calculator' you can calculate the density of the shipment using the overall dimensions and total weight.
