What does it mean to send cigarettes by express delivery and delete codes?

The reason for erasing the code may be to avoid the inspection of relevant departments. Because the "Tobacco Law" stipulates that cigarettes sold can only be purchased from local tobacco monopoly wholesale enterprises, and the code of cigarettes is like the ID number, which can find out the source of cigarettes. In order to avoid the inspection of relevant departments, unscrupulous merchants will deliberately erase bar codes.
