L/C上的FREIGHT INVOICE - 國貿工作討論

關於一筆出到IRAN的L/C
有個條款寫到:
SIGNED FREIGHT INVOICE ISSUED BY SHIPPING CO. OR ITS AUTHORIZED
AGENT(S) THE ORIGINAL TO BE CERTIFIED BY THE CHAMBER OF COMMERCE.
FREIGHT CHARGE ARE PAYABLE IN PROPORTION TO SHIPMENT AND
RESPECTIVE AMOUNT SHOULD EXACTLY CORRESPOND WITH THE AMOUNT OF
FREIGHT CHARGE AS QUOTED IN COMMERCIAL INVOICES.

我想這個條款要的是
船公司或AGENT的運費收據(要簽商會???)
且運費要和INVOICE上的運費相同.

可是問題1.運費收據也可以簽商會嗎?
2.船公司有發這樣的收據嗎?且如果對客人的運費是高報,那船公司
會願意發我們要的金額的FREIGHT INVOICE嗎?

因為我從來沒碰過,希望能有高手解答 謝謝!
