Core Viewpoint - The successful implementation of the "dual-function warehouse" reform for bonded fuel oil supply at Tianjin port marks a significant advancement in enhancing the operational efficiency and cost-effectiveness of international shipping services in the region [1][2]. Group 1: Policy and Regulatory Changes - Tianjin Customs has initiated a special action for cross-border trade facilitation, addressing the complexities and high costs associated with bonded fuel oil supply by implementing the "dual-function warehouse" reform [2]. - The reform allows the same warehouse to serve both as a bonded warehouse and an export supervision warehouse, streamlining the process for domestic fuel oil to be directly declared for export and stored without physical transfer [2]. Group 2: Operational Efficiency - The new process simplifies the operational workflow from the traditional "two in, two out" to "one in, one out," significantly reducing the time and costs associated with fuel supply operations [2]. - The capacity of the approved "dual-function warehouse" tanks totals 180,000 cubic meters, enhancing the utilization rate and safety of storage facilities [2]. Group 3: Economic Impact - The bonded fuel oil supply capability is a core function of international shipping centers and a key indicator of port internationalization and service capacity [1]. - The reform is expected to lower the operational costs for international shipping vessels by eliminating tariffs and import taxes on bonded fuel oil, thereby promoting the competitiveness of Tianjin as a shipping hub [1].

Core Viewpoint - The implementation of the "two warehouse" function overlap policy by Huangdao Customs has significantly improved the efficiency and cost-effectiveness of supplying domestic low-sulfur fuel oil for international shipping vessels in Qingdao [1][3][5]. Group 1: Policy Implementation - The "two warehouse" function overlap allows fuel oil storage tanks to simultaneously serve as both bonded warehouses and export supervision warehouses, simplifying the process of transferring fuel oil from export supervision to bonded status [3][4]. - This policy change has eliminated the need for physical transfer operations, reducing operational complexity from "two in, two out" to "one in, one out," thereby lowering costs for shipping companies [3][4]. Group 2: Economic Impact - It is estimated that the implementation of the "two warehouse" function overlap can save shipping companies over 20 million yuan annually in related costs [4]. - Over the past three years, the total supply of fuel oil in the Qingdao area has exceeded 7 million tons, indicating a robust growth in the supply oil industry [4]. Group 3: Future Developments - Huangdao Customs plans to continue releasing policy benefits related to the "two warehouse" function overlap, cross-district direct supply of fuel oil, and fuel oil blending to further support the regional shipping fuel supply industry [5].
