How can I bulk upload commodity (Customs Declaration) for international shipment?
We are shipping hundreds of gift boxes all over the world, it work great if there is only one item in our gift box, I can bulk upload them, but in most case, our gift box contain more than 1 item, then we had to manually add more customs declaration in each order... that was really headache for us.
Any insight? did I miss any information that I can upload multiple customs declaration?
Thanks in advance.
