Summary by Relevant Sections Customs Closure and Policy Framework - The customs closure operation is a landmark project for the Hainan Free Trade Port, aimed at further expanding openness and establishing a special customs supervision area across the island [1][2]. - The closure will implement a policy characterized by "one line" for free access and "two lines" for management, allowing for relative free flow of various factors within the island [1][2]. Key Policy Measures - Four key measures have been outlined for the customs closure: 1. A more favorable "zero tariff" policy for 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 designated ports, facilitating the flow of goods [2]. 4. A more efficient and precise regulatory model to ensure smooth implementation of the new policies [2]. Taxation and Trade Facilitation - The "zero tariff" policy will cover a broader range of goods, expanding from 1,900 to approximately 6,600 tax items, which constitutes about 74% of all goods [4][5]. - The scope of beneficiaries for the "zero tariff" policy will also expand to include various enterprises and non-profit organizations within the island [4][5]. Operational Efficiency and Management - The customs closure will not hinder the movement of people and goods between Hainan and the mainland, maintaining current management practices with minimal changes [6][7]. - A "one-stop customs clearance" model will be established to streamline the process, along with enhanced smart regulatory measures utilizing big data and AI [7][8].
