Importers are responsible for submitting TEN data elements to Customs 24 hours PRIOR to vessel lading. This rule applies to ocean shipments only. The ten data elements are as follows:
*These four elements can be amended at a later date.
** These two elements can be filed after the vessel departs but no later than 24
hours prior to U.S. arrival.
Who can file the ISF?
It is the importer’s responsibility to file the ISF. The ISF must be filed either via the
Automated Manifest System (AMS) or the Automated Broker Interface (ABI). Due to this
requirement, in most cases the importer will designate an authorized agent to file the
ISF on their behalf. The importer may designate either the AMS filing freight carrier or
their Customs Broker to file the ISF. As your Customs Broker, we already have the
authorization through our Customs Power of Attorney to file the ISF on your behalf.
