Quoting from [parvez]:
after receving goods from the customer if the goods are found defective, what should we do. the supplier taken lc payment from the bank.
If the terms of payment is LC, you should stupilate a condition that, the goods should be insepcted on line prodcution and after cmpletion of the production there should be quality and quantitiy inspection by the international inspection agency like SGS.
Then if the goods accompany with the certificates you can accept., and there will not be any problem;
If you have paid by TT or other method you donot have the chance for control.
