The exporter also must have an IEC (Import Export Code) number issued by DGFT (Director General of Foreign Trade). He has to file a Shipping Bill which has to be assessed by Customs and the goods are also subject to examination by Customs before LEO (Let Export Order) is given. This document can be filed with Customs upto 15 days before the goods are actually exported. Like in case of imports, in exports too, the document for assessment and examination by Customs (Shipping Bill) is processed through the EDI. To encourage exports, the Government has introduced various export promotion schemes i.e. Drawback, DEEC, DFRC, DEPB, EPCG, etc. and the exporter has a choice to avail any of them. However, certain schemes cast an export obligation on the exporter for which he is required to execute Bond and Bank Guarantee for certain period. Exports are also governed by the Customs Act, 1962, the EXIM Policy and are subject to prohibitions and restrictions imposed under various other Acts i.e. CITES, NDPS Act, Arms Act, Antiques Act, Drugs & Cosmetics Act, etc.
