Customs exemption cut-off date revised to extend eligibility for electricity supplies to domestic tariff area under SEZ approvals. The notification amends Notification No.50/2017-Customs by substituting the earlier cut-off date with the 19th July, 2012 in the Table entries at serial numbers 164 and 165, thereby modifying the temporal eligibility criterion for customs duty exemption on electrical energy supplied to the Domestic Tariff Area by large power plants formally approved for establishment in a Special Economic Zone.
