we are collecting delivery charges from our customers for delivering materials to customers location. We are collecting gst at 18℅ for it. we are dealing with material having tax rate of 12℅, 18℅, and 28℅.

Is it requires to collect tax at higher rate for delivery charges if we are suppling items with tax rate is 28℅ Under composit supply?

If we are supplying an item with delivery charges and we are showing it seperately in our invoice with different tax rate. Is it a composit supply or mixed supply?
