Freight charged in gst invoice

What will be the treatment of Freight included in GST invoice while filing GSTR1 return? I am aware of the fact that the tax rate will be the same as the rate on the item. For example- Item value Rs 100, Freight Rs 10 then my taxable value is Rs. 110 and same rate of tax will be applicable for this. But now my question is that how would I treat this in GSTR1? As we are not providing this service separate SAC code can not be used to show this.
