The Importer Security Filing is a U.S. Customs and Border Protection (CBP) regulation was developed to help prevent high-risk ocean shipments from being transported to the United States. It is commonly referred to as “10+2” because of the number of data elements required and requires importers to submit specific information pertaining to ocean cargo prior to departing the country of origin.

Country of origin
Commodity Harmonized Tariff Schedule of the United States (HTSUS) number
