S:Ah,Mr Yang.Sit down,won't you?Scar?

Y:Thank you,I believe I will.

BOk.I am glad to say that we have settled the price,quality,quantity of the transaction.And what about the terms of payment?

Y:We only accept payment by confirmed,irrevocable letter of credit,available against presentation of shipping documents.

S:But I heard you would accept different kinds of payment,such as DA and DP.

Y:Quite right.But that all depend on circumstances.

S:As this is the first transaction,I would suggest that you could give us more favorable term.What about DA?

Y:Sorry,it can not be done.Payment is our usual practice by all customers for such commodities,especially with our new customers.As a matter of fact,LC protects the seller as well as the buyer.

S:Then,is DP acceptable for you?

Y:Perhaps we shall consider it after we have more business together.But so far,we haven't known much about credit status each other.So,I am afraid we must insist our usual form.

S:To tell you frankly,the letter of credit will add my cost of imports.In opening the letter of credit with the bank,I have to pay the deposit,that will tight up my funds.

Y:You might consult to bank to see if they can reduce the require deposit to minimum.

S:Also,there will be certainly bank charges.It would help me greatly if you could accept DA or DP.You can join on me just as if there were letter of credit.To you,it makes no difference.But to me,it does.

Y:Well,Mr Sinclare.You must be aware that the irrevocable letter of credit gives the export additional protection of the banker's guarantee.We always requires LC for all exports.And the other way around,we pay by LC for our imports.

S:To meet each other health way,what do you say for fifty percent by LC and balance by DP?

Y:I am awfully sorry,Mr Sinclare.But I am cannot promise even that.As have said,we usually require the payment by LC,however,to get around your difficulties,I suggest you reduce your order by half,we can send in a additional order later.

S:Well,I will think it over.By the way,when must I open the LC,if I want to get goods to be delivered in June.

Y:A month before shipment.

S:Could you possibly affect shipment earlier?

Y:Getting the goods ready,making all the documents,booking the shipping space,all these takes time you know.You cannot expect us make the delivery in less than a month.

S:Very well.Mr yang.I should not reduce my order.I will take the full quantity you offer and arrange the LC as soon as I get home.

Y:When will that be?

S:Early next week.In the meantime,I shall be pleased if you could get everything ready.I hope these goods can be dispatched immediately after you get the LC.

Y:You may be assure of that.We will book the order and require the shipping space right away,so that the shipment can be affected within two or three weeks after receipt of your LC.

S:That will be fine.I appreciate your cooperation.

Y:The sooner we get your LC,the sooner shipment can be affected.

S:Thank you very much.Mr Yang.

Y:I am glad to be of help.
