The document outlines new requirements from US Customs and Border Protection (CBP) called "10+2" which requires importers and carriers to provide additional trade data in advance for non-bulk cargo shipments arriving in the US by vessel for security purposes, including requiring importers to file an Importer Security Filing (ISF) with 10 or 5 data elements depending on the cargo and requiring carriers to submit Vessel Stow Plans. CBP will have a flexible enforcement period to help the trade comply with a goal of improving supply chain security.
