00Please be informed that we have sent our docs for issuing LC more than one month, but we have no feedback from the bank. There is some problem in banks according to recent government's policy of Iran which has caused that issuing of the credit process is facing interrupt. We are searching to find a solution for this problem with our bank. 02br

00In case we do not succeed to open LC during the coming week, we ask you kindly about cash payment; please send your suitable payment terms. 02br

00The above situation has put us again in a critical time situation therefore we certainly need the shorten delivery time for Bushing Blocks against extra charges. So, please accept my apology for all inconveniences, we are sure you will appreciate our situation.0-
