I am the head of a small and medium-sized electromechanical manufacturing enterprise based in Shanghai. I just signed the agency export agreement with Zhongshen last week, and a batch of machine tool accessories will be shipped to Hamburg Port next week under the term of FOB Shanghai.

This is our first time conducting agency export, and I have never been exposed to foreign trade documents before. Yesterday I heard from a peer that a company's goods were detained at the port for 3 days because they missed a certificate of origin, which not only forced them to pay the customer liquidated damages but also affected the tax rebate. I am so anxious that I can't sleep now.

I would like to ask what documents I need to prepare for the whole process from customs declaration, logistics to tax rebate? Are there any special documents that are easy to miss in different links? And for FOB terms, are there any additional documents I need to prepare in advance for customs inspection?

In the customs declaration link of agency export, the logical consistency of documents shall be focused on. The draft customs declaration shall be completely consistent with the commodity name, HS code, quantity and weight on the commercial invoice and packing list. Wrong HS classification or quantity deviation is strictly prohibited.

If there is a customs valuation dispute, auxiliary documents such as purchase-sales contract, payment voucher and product cost accounting sheet shall be prepared in advance to avoid customs detention caused by failed valuation. In addition, for electromechanical products exported to the EU, the scanned copy of CE certification certificate shall be prepared in advance and submitted together with the customs declaration, otherwise it will be directly rejected by the customs, resulting in extra costs such as port storage fee and container rent.

Under FOB terms, logistics documents for agency export shall focus on the title of goods and terminal operation specifications. The consignee of the bill of lading shall be confirmed as the agency company (or the designated consignee required by the entrusting party), and the correct endorsement procedures shall be completed, so as to avoid that the title of goods cannot be transferred resulting in the customer's failure to pick up the goods. The packing list shall mark the accurate gross weight, net weight and volume of each carton.

If the deviation between the actual weight and the document exceeds 5%, the freight forwarder may charge extra overweight fee or adjust the shipping space, which will delay the shipment. In addition, the manifest confirmation shall be prepared in advance, and the consistency between manifest information and customs declaration shall be checked 24 hours before the document cut-off time, so as to prevent the goods from being unable to be loaded on board due to inconsistent manifest.
