What will be hsn code for discount (trade discount) on sale or purchase and late payment from party???

Reply-If discounts like Trade discount, quantity discount etc. are given before or at the time of the supply, GST will not applicable on such trade/Quantity discount.

In case of cause of penal charges is delay in payment of consideration, it will be added to the value of original supply as per section 15(2)(d) of CGST Act and will attract the same rate and HSN code as for original supply of goods or service.
