If you have your Amazon account set up, then you have to create a product listing first. Once your listing has been created then go to shipment and select send to Amazon. Now you will see your listing and you have to create a case pack template or individual units template, create a template by providing box dimensions and weight. Once your template has been created put in the number of boxes you wish to send, and get box labels. You can download item labels from the drop-down at the end of the listing. Once you have box labels and item labels send these to your manufacturer and he will send your inventory either by Air or by sea whichever you want to go with.
