Bill of Entry filing timelines updated: deadlines vary by port type and origin, with submission via the common portal. Amendments define 'Customs Automated System' as the Indian Customs Electronic Data Interchange System and substitute references to that expression with 'common portal.' The regulations set port-specific bill of entry filing deadlines: for sea ports filing is due before the day preceding vessel arrival except for certain neighbouring countries when filing is due by the day of arrival; for airports filing is due by the day of aircraft arrival; for inland container depots and air freight stations filing is due before the day preceding vehicle arrival; and for land customs stations filing is due by the day of vehicle arrival.
