Importer Security Filing, also known as “10+2”, is a U.S. Customs and Border protection regulation mandated for ocean cargo imports only. ISF is required to be filed with U.S. Customs and Border Protection 24 hours prior to sailing from last origin port.
In other words, importers should send all necessary data to their U.S. Customs Broker prior to shipping the order. Scarbrough files ISF 72 hours in advance and suggest importers to gather required data from their shippers as soon as possible.
Usually the ISF would be sent by customers’freight agent,but customers can do it themselves online to fill out the information needed.
