海南自贸港全岛封关12月18日正式启动，封关后到海南出差、旅游等不需要额外办理证件

Core Viewpoint - The official announcement of the specific date for the Hainan Free Trade Port's customs closure is set for December 18, 2025, marking a significant milestone in the expansion of openness and the development of the Hainan Free Trade Port [1][3]. Summary by Sections Customs Closure Policy - The customs closure will transform Hainan Island into a special customs supervision area, implementing a policy characterized by "one line open, one line controlled, and free flow within the island" [1][2]. - The "one line" refers to the open trade between Hainan and other countries, while the "two line" involves precise management of trade with the mainland [1][2]. Policy Measures - The customs closure will introduce four key enhancements: 1. A more favorable "zero tariff" policy for imported goods, increasing the proportion of zero-tariff items from 21% to 74% [2]. 2. More relaxed trade management measures, allowing for open arrangements for certain previously restricted imports [2]. 3. More convenient passage measures through eight designated "one line" ports and ten "two line" ports for efficient cargo movement [2]. 4. A more efficient and precise regulatory model to ensure smooth implementation of the open policies [2]. Symbolic Significance - The choice of December 18 for the customs closure is symbolically significant, aligning with the anniversary of China's reform and opening-up policy initiated in 1978, showcasing the country's commitment to high-level openness [3][4]. - The customs closure is seen as the beginning of a new phase in the development of the Hainan Free Trade Port, with ongoing efforts to enhance the policy framework and expand openness [3][4]. Operational Continuity - Post-closure, most goods, personnel, and transportation will continue to be managed under existing regulations, ensuring that travel and business operations in Hainan remain unaffected [4].
