Sign in to My Alibaba, find Logistics >> Manage logistics orders.
On the "Manage logistics order" page, locate the order you want to modify, and click "Modify order" under the "Action" column.
You will then see the page below, where you can make changes to your order and save them.
Please note that you can only modify your order before the freight forwarder confirms it. Contact the freight forwarder directly if you want to make changes after the order has been confirmed.
