This form is needed for the immediate release of imported goods to the importer or customs broker. While the imported goods may be removed from the port of entry, they are still considered to be in the custody of the Customs Service until the entry package has been filed. Issued by the Customs Service district director, this form provides proof of release to the importer, customs broker, carrier and Customs Service. It is also known as the "Release Document," the "Permit" and the "Delivery Authorization Document."
