Customs data refers to information collected, organized, statistically processed, and published by national customs authorities regarding import/export goods and their transportation, prices, quality, origins, etc. These data typically reflect a country or region's import/export trade activities, trade structure, trading partners, and related information. China's customs import/export data serves as a critical source for understanding Chinese enterprises' international trade activities, characterized by comprehensiveness, granularity, reliability, and customizability. It holds significant value for businesses and research institutions in formulating trade strategies and conducting market analyses.
