Article 11

Teletransmitted and Pre-Advised Credits and Amendments

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.

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.
