Exemption amendment expands tariff entries and adds ammunitions coverage for specified defence imports under customs notification. Amendment modifies the exemption table for serial numbers 10-13 by substituting 'or 90' with '90 or 93' in column (2), removing the standalone word 'Ammunition' in column (3), and inserting a new item (III) stating 'Ammunitions for the goods mentioned at item (I) above,' thereby clarifying tariff classification and expressly extending exemption coverage to ammunitions related to the listed defence goods.
