  Under China's 14th Five-Year Plan for port development, consolidating and refining the port fee catalog publicity system constitutes a critical initiative. Implementing catalog-based management of port fees, ensuring explicit fee labeling, and enhancing fee transparency represent essential requirements for optimizing port business environments and facilitating cross-border trade.

  CnOpenData presents China Port Fee Schedule Data. This dataset encompasses port fee catalog information from 31 provincial-level administrative regions, incorporating fields such as province(省份), charging entity(收费主体), port type(口岸类型), fee item(收费项目), and fee standard(收费标准), thereby supporting relevant research endeavors.
