My query is as follows: Suppose I issued a tax invoice (Invoice no 001) and this Invoice has 4 categories of Stock let's say A, B, C, and D. Each category has a different GST rate say 5%, 12%, 18%, and 28% respectively.
Now I have to charge freight from a buyer let's say Rs 5000 on this Invoice then what rate of GST would be applicable on freight charges of RS 5000?
