11.2 Section 53(2) of the SEZ Act, 2005 creates a deeming fiction whereby a SEZ is deemed to be a port, airport, inland container depot, land station and customs stations under section 7 of the Customs Act, 1962. On the other hand, Circular Nos. 46/2017-Cus dated 24.11.2017 and 3/1/2018-IGST dated 25.05.2018 clarified applicability of IGST / GST on goods transferred / sold while being deposited in a warehouse registered under section 57 or 58 or 58A of the Customs Act, 1962 (customs bonded warehouse), without payment of duty. The purpose of appointing any port, airport etc. under Section 7 of the Customs Act, 1962 is quite different than the purpose of licensing any warehouse under Section 57, 58 or 58A of the Customs Act, 1962. Therefore, the clarification issued for customs bonded warehouse are not applicable to the appellant even if a SEZ is deemed to be a port etc. under Section 7 of the Customs Act, 1962. Further, the appellant is engaged in providing services whereas the customs port etc. are appointed under Section 7 of the Customs Act, 1962 and customs bonded warehouses are licensed under Section 57, 58 or 58A of the Customs Act, 1962 in respect of import of export of goods and not of services.
