Import manifest filing: registration, EDI access and specified advance timelines govern filing obligations and compliance. Any person delivering an import manifest under Section 30 of the Customs Act, 1962 must register with Customs and submit prescribed information (Form V/Form VI/Annexure A) to obtain EDI access; registration uses existing business codes or a 12 digit consol format, and access follows submission plus verification by the designated Port/Airport/ICD. Master level filing is the responsibility of the person in charge or their agent and house level filing by the person under Section 30, with electronic filing required where ICES operates and specified advance timelines for voyages and flights; failure invites action under Section 30(1).
