"Received the goods as specified above according to Shipper's declaration in a apparent good order and condition unless otherwise stated herein - weight, measure, marks, numbers, quality, contents and value unknown for carriage from the place of receipt or port of loading to the port of discharge or place of delivery, whichever is respectively applicable"
Не могу понять, что в данном случае такое unknown for carriage? и как вообще можно сформулировать эту фразу?
