Power to exempt imported materials used in the manufacture of goods in warehouse.

    If any imported materials are used in accordance with the provisions of section 65 for the manufacture of any goods and the rate of duty leviable on the imported materials exceeds the rate of duty leviable on such goods, the Central Government, if satisfied that in the interests of the establishment or development of any domestic industry it is necessary so to do, may, by notification in the Official Gazette, exempt the imported materials from the whole or part of the excess rate of duty.
