Paperless processing via digitally signed supporting documents enables online submission and mandatory linkage to Bills of Entry after pilot review. A pilot implements paperless processing on ICEGATE allowing authorized persons to upload digitally signed supporting documents for Bills of Entry processed on ICES. The facility permits voluntary use initially, followed by a mandatory requirement after review. Uploading requires use of access credentials, e SANCHIT, obtaining Image Reference Numbers for documents, and linking documents to Bills of Entry; amendments to link documents after Bill generation must be submitted through Service Centres.
