China Customs Statistics (CCS) comprises all merchandises passing through ChineseCustomsTerritory and provides the basic information on China's external trade performance.

    CCS is compiled from the declarations submitted to the Customs by importers or exporters. The declarations are verified by Customs officers at entry ports and forwarded electronically through Customs Automation Entry System to relevant Customs Districts for further examination and clearance. Data elements for compiling trade statistics are extracted and verified by the statistical offices, and afterwards transmitted on line from all Customs districts to the computer center of CGA on a monthly basis. The statistical elements taken from declarations include: commodity code and description; quantity; value; partner country (origin, final destination, consignment); type of customs regimes; type of enterprises; individual importer or exporter; domestic destination for imports; places of production for exports; customs district of clearance; mode of transport.
