Core Viewpoint - The General Administration of Customs of China has developed regulatory measures for the Hainan Free Trade Port to implement "zero tariffs" on imported goods and to streamline trade management, ensuring effective customs supervision after the island's closure to external trade [1]. Group 1: Import Regulations - The customs will enhance the facilitation of customs clearance for imported goods, allowing "zero tariff" goods and bonded goods to be released directly, except for those requiring inspection or permits [2]. - The policy was initially piloted in the Yangpu Bonded Port Area in June 2020 and has since expanded to other areas, significantly improving clearance times and reducing costs for enterprises [2]. Group 2: Export Regulations - Customs will establish both customs supervision channels and non-customs supervision channels at the "second line" ports, managing "zero tariff" goods and those benefiting from processing and trade management policies [3]. - A new "batch export, centralized declaration" model will be implemented, allowing enterprises to handle export procedures first and then complete customs declarations later, thus improving efficiency [3]. - The number of declaration items required for "second line" exports has been significantly reduced from 105 to 42, simplifying the process for enterprises [3].
