The island wide customs operation is a landmark project in the construction of Hainan Free Trade Port, an important measure to further expand opening up, and has milestone significance. With the approval of the Party Central Committee, the island wide customs operation of Hainan will be officially launched on December 18, 2025. "At the press conference held by the State Council Information Office on the 23rd, Wang Changlin, Deputy Director of the National Development and Reform Commission, said that the island wide customs operation is the beginning of a new stage of opening up and development of Hainan Free Trade Port, and it is also a long-term and continuous task to promote. We will make urgent preparations in the near future to help business entities fully understand the customs clearance policy and conduct relevant business tests. Customs closure refers to the establishment of a special customs supervision area on the entire island of Hainan, and the implementation of a liberalization and facilitation policy system characterized by "opening up the 'first line', controlling the 'second line', and allowing freedom within the island". Wang Changlin introduced that the opening up of the "front line" refers to the implementation of a series of free and convenient entry and exit measures between Hainan Free Trade Port and other countries and regions outside China's customs territory as the "front line"; Controlling the "second line" means treating the relationship between Hainan Free Trade Port and the mainland as a "second line" and implementing precise management for the content that is opened up in the "first line". Wang Changlin introduced that according to the current customs clearance system design, except for some goods that need to undergo inspection when entering the mainland from Hainan Free Trade Port, most goods and all personnel, items, transportation vehicles, etc. entering and leaving Hainan Island will still be managed according to the current regulations, and there will be no changes before and after customs clearance. No additional documents are required for business trips or travel to Hainan Island. Sealing off is not about sealing off islands, but about further expanding openness. ”Wang Changlin stated that after the closure, Hainan's connection with the international community will become more convenient, which is of great significance for accelerating the attraction of high-quality global factors, promoting the high-quality development of Hainan Free Trade Port, and paving the way for national reform and opening up.
