Sea Cargo Manifest Transhipment Regulations require ICEGATE registration and dual-format message testing before full format switchover. The notification requires all stakeholders to register and apply via ICEGATE to operate under the Sea Cargo Manifest Transhipment Regulations, with entities filing specified messages and manifests. Some classes must satisfy particular registration conditions such as pre registration of a National Surety Bond, while others receive auto approval after meeting ICEGATE prerequisites. Entities performing multiple roles must submit separate applications. During the interim testing phase stakeholders must transmit both existing and new format messages to ensure smooth switchover; registration approval queries are handled online with manual submission of additional documents where required.
