In South Korea it is very common for people to also confuse the expiration date of the product with the date of manufacture of the products.
Typically, Korean brand manufacturers include only the date of manufacture on the product packaging, on account of the batch, and this is normally done for non-perishable products.
How to differentiate the manufacturing date (MFD) with the expiration date (EXP) of a product coming directly from South Korea?
If in doubt about this, check the back of the package, if you see the date followed by "제조", it means the date of manufacture (MFD) of the product.
If you see the date followed by "까지", then it means that the product expires on that date.
