Thanks for your below e-mail.
FYI, we have checked the tins for "O" mark as you have mentioned in your below e-mail, but we couldn’t find any tin with such mark. Even our customer opened a fresh tin without "O" mark & found cut baby corn packed in the tin instead of sweet corn. The problem is now we have more than half container goods in our warehouse & we are not sure how many cartons have such problem & we cannot even separate the tins as there is no such marking as you have mentioned. Pls find attached photos for your ref. Kindly check & let us know your feedback ASAP.
