Exports without payment of integrated tax: LUT/Bond may be furnished; manual submission accepted; bank guarantee required. Exports as zero-rated supplies may proceed without integrated tax by furnishing Form GST RFD-11 (Bond or LUT) to the jurisdictional Superintendent before export; a Bond must be secured by a bank guarantee and all submissions must be recorded at office level. Manual filing is permitted until the common portal is available, and Superintendents must adhere to central notifications and circulars governing conditions, safeguards and timelines that trigger tax liability with interest if export or foreign exchange receipt does not occur within prescribed periods.
