Authority Directives: ICES Advisory No. 13/2026 (DG Systems & Data Management, CBIC) | Public Notice No. 36/2026 (Kolkata Custom House)
The Central Board of Indirect Taxes and Customs (CBIC) has operationalized enhanced functionalities within the Custom Automated System across Special Economic Zone (SEZ) locations. This infrastructure upgrades supply chain logistics by enabling seamless, end-to-end digital movement of goods between SEZs and Custom Bonded Warehouses (CBW) without the requirement of upfront Import General Manifest (IGM) details or immediate duty payments.
This framework replaces manual reconciliations with automated system ledgers and bond allocations. Supply chain leaders must adhere to the following precise electronic filing paths to maintain compliance and avoid working capital blockages.
Outbound Transfer: SEZ to Custom Bonded Warehouse
This protocol manages the transit of goods from an SEZ location into a Domestic Tariff Area (DTA) entity’s Custom Bonded Warehouse.
Step-by-Step Electronic Filing Path:
- Initial Filing Requirements: The receiving DTA entity (or the SEZ unit acting on its behalf) must file a Bill of Entry (BE) within the SEZ portal, structured strictly as Type W.
- Importer Classification: The importer type must be declared as “T/M” (‘T’ for goods cleared as-is; ‘M’ for goods cleared post-manufacturing).
- System Declaration (SW Table): The filer must input the corresponding ‘Z’ Type BE details and the designated destination Warehouse Code directly into the SW Table.
- Bond Utilization: The filing must declare the receiving DTA entity’s Triple Duty Bond (Warehouse Bond).
Automated Ledger & Bond Execution:
- Upon Submission: The system automatically debits the specified cargo volume from the SEZ ledger.
- Upon Assessment: The digital portal automatically debits the DTA unit’s Triple Duty Bond.
- Upon Out-of-Charge (OOC): Once the specified customs officer grants OOC, the Custom Bonded Warehouse ledger is instantly credited against the DTA unit, and the originating SEZ unit’s bond is automatically credited back.
Inbound Transfer: Custom Bonded Warehouse to SEZ
This outlines the reverse transit protocol, allowing SEZ units to pull previously warehoused goods back into their specialized zone.
Step-by-Step Electronic Filing Path:
- Initial Filing Requirements: The destination SEZ unit initiates the transfer by filing a “Z” Type Bill of Entry.
- Importer Classification: The importer type must be configured strictly as W.
- System Declaration (SW Table): The filer must reference the original ‘W’ Type BE (the document utilized during the initial outward transit) and the warehouse code inside the SW Table.
Ex-Bond Clearance & Ledger Adjustments:
- Upon Submission: The cargo volume is automatically debited from the Custom Bonded Warehouse ledger.
- Upon Assessment: Following review by the Specified Officer, the SEZ unit’s S_Z Bond is debited.
- Shipping Bill Mandatory Filing: The DTA entity must subsequently file an Ex-Bond Shipping Bill (SB) directly with the Customs Officer, referencing the new “Z” Type BE number and date to trigger the system’s auto-population sequence.
- Let Export Order (LEO): The Customs Officer will grant an LEO. Note: Goods registration at the destination cannot be executed until this LEO is successfully generated.
- Finalization & Inventory Reconciliation: Upon physical arrival, the SEZ officer performs goods registration and grants the final OOC, triggering a volumetric credit back into the SEZ unit’s internal inventory ledger.
