Certificate of Origin: Indian customers do CO, and they need to have the IEC, PAN, GSTIN number on the receipt. The invoice and packing information of the customs clearance form must be accurate, because the Indian customs charges tariffs based on the gross weight. The BL bill of lading is ready, and it can be sent to the customer by telex after sailing, so that the shipping company can release the goods to the customer smoothly after arriving at the port. The customs clearance document is a document for the customer's destination country; the bill of lading is a delivery certificate to the shipping company. The document requirements of different countries are different. Some countries require a scanned copy, and some countries must require the original document. Therefore, we must confirm and inform the customer clearly to ensure that the customer can receive the goods in time (industry knowledge, documents that must be understood by foreign traders)
