Importer Security Filing

ISF (Importer Security Filing) is a rule that obliges importing US parties to declare specific data (description of commodity) of the imported goods to the US Customs. Customs need to receive the declaration latest 24 hours prior to loading. The complete ISF must be declared 48 hours before vessel’s departure out of the port of loading.

Strict compliance

US Customs used to comply this rule flexible, but since July 2013 the compliance is much stricter. Late declarations will be penalized with a fine of USD 5.000 till USD 10.000 per ISF.
