全岛封关后——货物、人员等进出如何管？便利性是否受影响？

Core Viewpoint - The establishment of the "second line port" in Hainan Free Trade Port aims to facilitate efficient and secure transportation of goods, personnel, and vehicles between Hainan and the mainland, supported by a series of policy documents and management measures [1][6]. Summary by Relevant Sections Customs Management - Three categories of goods, including "zero tariff" goods, processing and value-added goods exempt from tariffs, and goods benefiting from relaxed trade management measures, must pass through the customs supervision channel at the "second line port" [2]. - Non-customs supervised goods, personnel, items, and vehicles will be managed according to existing regulations without additional inspection or documentation requirements [2]. Passage Management - To enhance the efficiency of the "second line port," several innovative facilitation measures will be implemented: - A "one-stop customs clearance" model will be established, allowing enterprises to declare goods online in advance, with customs and security departments coordinating operations for streamlined clearance [3]. - The management of certain procedures, such as agricultural product inspections and additional fee collections, will be relocated outside the port area to prevent congestion [4]. - Smart supervision will be strengthened through the use of big data and artificial intelligence, promoting information sharing and mutual recognition among customs, maritime, border inspection, and port operation units [5]. - A credit management system will be developed to classify and regulate services based on credit ratings, reducing inspection frequency for high-rated enterprises to facilitate faster clearance [6]. Overall Outlook - The Hainan Free Trade Port is expected to maintain convenient exchanges with the mainland post-closure, providing enhanced intelligent and convenient passage experiences for various entities, especially tourists [6].
