Customs declaration is the mandatory process of legally importing or exporting goods across national borders. For newcomers to international trade, the complexity of procedures and documentation requirements can be overwhelming. This guide breaks down the fundamentals.

The export declaration involves: preparing required documents including contracts, commercial invoices, and packing lists; submitting electronic declarations through China International Trade Single Window; awaiting customs review and potential inspection; and receiving clearance for shipment loading.
For imports, the process mirrors exports but in reverse. After goods arrive at the destination port, the importer or agent submits an import declaration, pays applicable duties and VAT, and after customs clearance, the goods can be released from the port.
