ISF 10+2 Carrier Requirements
In addition to the previous carrier requirements pursuant to the 24-Hour Rule, the ISF 10+2 requires carriers to submit a vessel stow plan and container status messages for certain scenarios pertaining to cargo containers destined to the United States.
Vessel Stow Plan
Carriers must transmit the stow plan, via the Automated Manifest system (AMS), secure file transfer protocol or email, so that it is received by CBP no later than 48 hours after the carrier's departure from the last foreign port. For voyages less than 48 hours, CBP must receive the information prior to the vessel's arrival at the first port in the U.S. The stow plan must include the vessel name, vessel operator and voyage number. With regard to each container, the vessel stow plan must also include the container operator and the equipment number, equipment size and type, stow position, hazmat code, port of lading and port of discharge.
Container Status Messages (CSM)
CSMs must be submitted to CBP daily for certain events relating to all containers laden with cargo destined for the U.S. by vessel. Carriers must submit a CSM when any of the required events occurs if the carrier creates or collects a CSM in its tracking system reporting that event. For each CMS submitted, the following information must be included: event code being reported, container number, date and time of event being reported, status of the container (empty or full), location where the event took place, and vessel identification associated with the message if the container is associated with a specific vessel. This must be done no later than 24 hours after the message is entered into the carrier's equipment tracking system.
