Entity registration under Sea Cargo Manifest regulations requires ICEGATE applications and customs approval for shipping stakeholders and exporters. The Sea Cargo Manifest and Transshipment Regulations require entity registration and ICEGATE filing by shipping lines, agents and exporters; master applicants must submit authorised persons, intended operations and supporting documents via ICEGATE, after which jurisdictional customs officers in ICES will verify, approve, or raise queries. A technical guidance note and application materials are available on ICEGATE, and unregistered entities-notably E Seal users-are advised to register.
