Because goods stack in a container for a month or more during sea transportation, your supplier need to pack them appropriately to keep them safe while travelling from the factory to the loading port warehouse, then to the discharge port warehouse, and lastly, to your destination on a truck. Because the items must travel a long distance to reach you, your Chinese supplier must ensure that their export packaging is adequate for the task. Packing your goods with five layers of the interior carton, five layers of the exterior carton, plastic wrapping on the exterior carton, IPPC ISPM 15 Standard Pallets, and the Freight Remark stamped on the outer carton of your package. It is preferable to inform your supplier with detailed packaging instructions because they may make mistakes that result in damage to your goods. Also, if necessary, give them visual examples.
