Every parcel that crosses a border is registered by the customs authorities. This process requires documents confirming the value of its contents, the status of the sender and receiver, and reason for the shipment.
For commercial goods, an invoice, packing list, and product specification is required. More documents can be requested by CDEK Customs Clearance.
When placing an order, indicate the receiver's email address and provide links to the goods being sent, e.g. from 1688.com, alibaba.com, taobao.com, Made-in-China.com, etc.
