Centralized bank guarantee custody required to standardize processing, ensure auto renewal and restrict direct encashment. A Centralized Bank Guarantee Cell is established under the Deputy/Assistant Commissioner (Bond) to receive and custody all customs-related BGs; accepting units must ensure an auto renewal clause and IEC code in BGs, enter BGs in the EDI system, hand them to the BG Cell with receipt numbers, and obtain BG returns only by written demand. The cell will not directly release or encash BGs, and units must inventory and forward existing BGs within thirty days and maintain records of receipt, dispatch and disposal.
