Cst on freight

I want to know whether I need to charge CST @ 2% on Freight which is shown separately in the same invoice -eg

A. Item XXX                           1000

B. Freight                                200

C. Cst @ 2% on A                     20

Total                                      1220

Is the above working correct ? Or do we need to charge on A + B
