"Customs clearance" is a customs term, that is, Hainan Island becomes a "domestic customs clearance" area, and Hainan Island can enjoy preferential policies such as zero tariffs. In this particular area, the concept of "customs clearance" can also be abbreviated as: first-line clearance, second-line control, and freedom on the island.
"First-line liberalization" refers to the free entry and exit of goods abroad and in areas not subject to customs supervision, that is, the free flow of goods, funds and people between the free trade zone (Hong Kong) and overseas. "Second-line control" means that goods entering and leaving other parts of the country from the free trade zone (Hong Kong) are brought into national customs clearance, subject to routine supervision, and the corresponding taxes are collected and included in trade statistics. It can be seen that the "first line" is external, the "second line" is internal, and the island is free.
Li Shijie, president of Hainan Open Economic Research Institute, explained this. Li Shijie: "First-line liberalization" means that Hainan and other countries and regions outside Chinese mainland are open, and international goods can freely enter and leave Hainan, allowing Hainan to achieve a high degree of freedom in trade with the world; "Second-line control" means that international goods entering the mainland are still subject to domestic supervision to ensure the consistency of domestic trade. If goods enter the mainland, customs duties will be levied.
"Guan" is not "Guam". On the contrary, the island's closure operation means that the communication between Hainan Free Trade Port and the outside world will be smoother and more open.
On the other hand, under the island-wide customs clearance operation, the communication between Hainan Free Trade Port and the mainland in terms of goods, articles and means of transport is "managed", which also brings challenges and opportunities for the system construction of the free trade port.
