Dear experts
A company clears goods say at Rs. 100 per unit and pays duty of Rs. 12.36 at 12.36% as per existing Purchase order (PO). However, after a month after the goods are cleared by adopting transaction value of Rs. 100, the PO is revised with back date revising the price per unit as Rs. 90. Payment is received as per the revised rate of Rs. 90. Can the company get refund of the excess duty paid initially on Rs. 100 which is Rs. 10 more than the revised price of Rs. 90 per unit. In other words can the company get refund of duty which is the difference between Rs. 12.36 (being 12.36% on 100)and Rs.11.12(being 12.36%on 90) in the above example . Pl offer views.
