Pakistan did not have certificate of origin? I am doing a letter of credit that come from Pakistan, is an old customer, there are no requests in the letter of credit - Pakistani origin (FTA), but the clerk said that our customer is necessary, so I went for, and After this I came back only to find the certificate filled out by HS CODE provided letters of credit with the customer is not very consistent, a little bit different, but the first four are the same, now the problem is that I do not need to change the card, I am worried card will not change if the customer when the clearance certificate on the tariff can not qualify for preferential tariff, the trouble to understand friends Geigejianyi, thank you.
