Or just let the customers know, that the whole batch - your phone is in - is being shipped.
And if Rhenus indeed manages the shipment from The Netherlands as well, they might be responsible for assigning all the parcels in one batch directly to the individual customer.
(Somehow I do not see the container delivered to FP-office Amsterdam, where they open it up to add adress stickers to every single parcel. 
)
