Hi,

I have a shipment coming. The full value was provided in the LC but value was declared as 2 containers instead of 1 (although net quantity or unit price not mentioned in the LC and supplier also don't know this fact). My intention was to take delivery asap by providing full value in LC and pay half the amount later by T/T once documents r ready to b sent to my bank. Now when the shipment is made, my supplier is saying they can't change value due to the fact that the current value is submitted in all shipping D/O! First of all I don't know what is meant by D/O in export & the exact process in case of export via LC as I m only importing. Is there anywhere on the export documents my supplier declares value accourding to LC? If they do is there any way to amend it if needed? Secondly, if I want to pay half of the LC amount by T/T asap now and make a value amendment on the LC and ask my supplier to prepare commercial invoice accordingly, is there a problem with that as the ship is already on the way?

Need urgent advise. Thanks in advance.
