海南全岛封关：不是封闭，而是开放升级

Core Viewpoint - The Hainan Free Trade Port will officially start its customs closure on December 18, 2025, which is aimed at enhancing openness and facilitating international trade, rather than creating a closed-off environment [2][3]. Group 1: Customs Closure Definition and Implications - Customs closure refers to establishing Hainan Island as a special customs supervision area, implementing a policy characterized by "one line open, one line controlled, and free flow within the island" [3][5]. - The customs closure is expected to enhance Hainan's connectivity with international markets, attracting global quality resources and promoting high-quality development [4]. Group 2: Implementation of Customs Closure - The "one line open" policy will allow for a series of free and convenient measures for entry and exit between Hainan and other countries and regions outside of China [6]. - The "one line controlled" policy will involve precise management of the content that is opened to the outside world, specifically between Hainan and the mainland [7]. - The internal free flow policy will enable various factors to circulate relatively freely within the Hainan Free Trade Port [7]. Group 3: Zero Tariff Expansion - The range of "zero tariff" products will significantly increase from the current 1,900 tax items to approximately 6,600 tax items after the customs closure [9]. - This expansion means that about 74% of all product tax items will be covered, which is an increase of nearly 53 percentage points compared to before the customs closure [11]. - The beneficiaries of this policy will include various enterprises, institutions, and non-enterprise units with actual import needs across the island [11].
