If the seller’s bank believes that the papers are authentic and pays the scammer, the buyer will never see the goods and will spend much time in discussions with his bank.

Always ask the seller to fax you the drafts of all the papers which are supposed to be sent to the bank. Check them carefully. Most of the shipping lines have online tracking system, where by entering the container number you can see when the cargo actually left the port and to which destination. If all looks acceptable, ask the seller to issue the originals and send copies to you by fax or e-mail. By B/L number you can always trace any shipment.It is a good idea to ask your bank (opening bank) to send you the copies of the documents received. You can check them before the bank pays the seller.You can include other papers to be presented to the issuing bank: inspection reports issued by an independent inspection company, all kind of documents issued by the official organisations of the exporting country etc.
