Excise exemption for jewellery manufacturers from annual return filing introduced, adding them to the existing exempt class. Amendment inserts a new clause exempting the manufacturer or principal manufacturer of articles of jewellery or parts of articles of jewellery falling under the tariff classification for jewellery from the requirement to file the annual return under the principal notification, thereby expanding the class of persons covered by the existing exemption in Notification No. 17/2006-Central Excise (N.T.).
