What is an ISF?
An Importer Security Filing (ISF), also known as “10+2,” is a filing required by the CBP that documents importing information and details, as shipments pass from point to point. Importers who do not file the ISF properly prior to the shipment of their goods will be penalized (US$5,000 fine). The ISF must be transmitted at least 24 hours prior to an ocean's shipment's departure to the United States.
