Specified machinery exemption expanded to include drier cum calciner, altering customs tariff relief under notification; amendment adds item to exemption table. The Central Government amended Notification No. 90/92-Customs by inserting, against S. No. (ii) in column (2) of the Table after item 5, a new item 6: Drier-cum-calciner, thereby adding that machinery to the list of equipment covered by the notification's exemption provisions.
