BENEFICIARY'S CERTIFICATE ADDR

L/C requirees:

"BENEFICIARY'S CERTIFICATE ADDRESSED TO ISSUING BANK CONFIRMING THEIR ACCEPTANCE AND OR NON-ACCEPTANCE OF ALL AMENDMENTS MADE UNDER THIS CREDIT QUOTING RELEVANT AMENDMENT NO. IF THE CREDIT HAS NOT BEEN AMENDED, SUCH CERTIFICATE IS NOT REQUIRED."

请问大家会如何处理个单证?"TO"给开证行还是"TO"客户?主要是"ADDRESSED TO ISSUING BANK "不太确定是什么意思.

还望指教.
