Excuse me, what proof is issued by the additional terms of this letter of credit?
it is quite easy to do so. First of all, the bill of lading issued by the shipping company or shipping agent will contain what you wrote, such as 1 2 3 4 5 6 7 8 10. Then you write the letter of credit number in the remarks, and then attach a piece of white paper with the contents of 1 12, which will be fixed with the bill of lading.
