There are three main inquiry methods:

1. Check the mask packaging to see if the manufacturing company, supervisory unit, production address, production license number, etc. are clearly written on the packaging. Details, without these, it is fake.

2. Check on the official websites of the Food and Drug Administration and the Quality Supervision Bureau whether the company has been successfully registered and whether it has passed quality testing. If it has not been registered and has not passed quality testing, it is fake.

3. Check whether the certificate number is printed on the packaging box, whether there is a scannable barcode, and whether there is a stamped production date/expiration date on the mask bag. If not, it is fake.

Note:

1. Be sure to compare the product name and ingredients registered with the Food and Drug Administration to see if they are consistent

2. Check whether there is a registered trademark on the packaging box ?, and food safety mark QS
