Container Security Initiative (CSI) is a program intended to help increase security for containerized cargo shipped to the United States from around the world. CSI addresses the threat to border security and global trade posed by the potential for terrorist use of a maritime container to deliver a weapon.
Whether you are a visitor to the United States or U.S. citizen, each individual arriving into the United States must complete one or more of U.S. Customs and Border Protection's (CBP) entry forms.
The Global Maritime Operational Threat Response Coordination Center supports the inter-agency response to maritime threats involving U.S. interests worldwide.
The transit and border layer (Trans-Border) is composed of transit to the U.S. from a foreign port of departure or non-port of departure, as well as passing through the U.S. border prior to entering the U.S. interior. This represents the last opportunity to detect radiological or nuclear materials prior to their arrival onto U.S. territory, and initiatives in this layer emphasize maritime domain awareness related to preventive radiological/nuclear detection.
