The difference between export purchase order customs declaration and regular customs declaration:

Purchase order customs declaration: refers to the export verification form that the factory or trading company does not have import and export management rights, or does not want to use their own company's header name. If there are goods to be exported, a company with import and export management rights needs to act as an agent for export. The customs broker will provide enterprise documents with import and export management rights to handle the customs declaration procedures for the goods, and the exporter only needs to provide the packing list and SO.

Ordinary customs declaration: refers to the enterprise providing a customs declaration certificate, and the customs broker only issues a customs declaration and other related documents to declare to the customs based on the enterprise's customs declaration certificate.
