跟单信用证：修改和指定

　　第十一条电讯传递与预先通知的信用证和修改

　　a. An authenticated teletransmission of a credit or amendment will be deemed to be the operative credit or amendment, and any subsequent mail confirmation shall be disregarded.

　　If a teletransmission states "full details to follow" (or words of similar effect), or states that the mail confirmation is to be the operative credit or amendment, then the teletransmission will not be deemed to be the operative credit or amendment. The issuing bank must then issue the operative credit or amendment without delay in terms not inconsistent with the teletransmission.

　　a.经证实的信用证或修改的电讯文件将被视为有效的信用证或修改，任何随后的邮寄证实书将被不予置理。

　　若该电讯文件声明"详情后告"（或类似词语）或声明随后寄出的邮寄证实书将是有效的信用证或修改，则该电讯文件将被视为无效的信用证或修改。开证行必须随即不延误地开出有效的信用证或修改，且条款不能与与电讯文件相矛盾。

　　b. A preliminary advice of the issuance of a credit or amendment (“pre-advice”) shall only be sent if the issuing bank is prepared to issue the operative credit or amendment. An issuing bank that sends a pre-advice is irrevocably committed to issue the operative credit or amendment, without delay, in terms not inconsistent with the pre-advice.

　　b.只有准备开立有效信用证或修改的开证行，才可以发出开立信用证或修改预先通知书。发出预先通知的开证行应不可撤销地承诺将不延误地开出有效的信用证或修改，且条款不能与预先通知书相矛盾。

　　Article 12 Nomination

　　第十二条指定

　　a. Unless a nominated bank is the confirming bank, an authorization to honour or negotiate does not impose any obligation on that nominated bank to honour or negotiate, except when expressly agreed to by that nominated bank and so communicated to the beneficiary.

　　a.除非一家被指定银行是保兑行，对被指定银行进行兑付或议付的授权并不构成其必须兑付或议付的义务，被指定银行明确同意并照此通知受益人的情形除外。

　　b. By nominating a bank to accept a draft or incur a deferred payment undertaking, an issuing bank authorizes that nominated bank to prepay or purchase a draft accepted or a deferred payment undertaking incurred by that nominated bank.

　　b.通过指定一家银行承兑汇票或承担延期付款承诺，开证行即授权该被指定银行预付或购买经其承兑的汇票或由其承担延期付款的承诺。

　　c. Receipt or examination and forwarding of documents by a nominated bank that is not a confirming bank does not make that nominated bank liable to honour or negotiate, nor does it constitute honour or negotiation.

　　c.非保兑行身份的被指定银行接受、审核并寄送单据的行为既不使得该被指定银行具有兑付或议付的义务，也不构成兑付或议付。
