I am the foreign trade manager of a dried fruit manufacturing enterprise. We are planning to expand into European markets such as Germany and France recently, but we have never been involved in export agency business before. Last month, when we conducted a small-batch trial order, incomplete commodity inspection documents led to 7 days of detention of the goods at Shanghai Port, generating total container detention fees and storage fees of 23,000 yuan. The finance department also reminded that the export tax refund process is complicated, and we are worried that repeated mistakes will affect capital turnover. Now we intend to entrust a professional agency, but we do not know the full process details of dried fruit export agency, the core materials that need to be prepared in advance, and how to avoid risks of inspection-related port detention and delayed tax refunds. We are very anxious and hope to get detailed guidance to avoid similar mistakes again.
