Exemption to Singapore-origin goods: government lowers qualifying percentage thresholds for import exemptions under Customs Act. Central Government directs targeted amendments to two exemption notifications for goods of Singapore origin by substituting the preambular percentage thresholds in Notification No. 74/2005-Customs and Notification No. 75/2005-Customs with lower figures, thereby changing the qualifying threshold for the specified import exemptions; the notification identifies the instruments amended and records prior publication and amendment history.
