I looked up information about several imported milk companies and found that most of the brands' companies and addresses were in China. The only imported milk brand registered in Germany, whose products are not sold in Germany.

9 to 12
months. Reporters compared with domestic warm milk found that the domestic milk market has a shelf life of
30
days of plastic bag packaging warm milk, has a shelf life of
45
days of Leer bag of warm milk, the shelf life is longer boxed products, its time is only half of imported warm milk, that is,
6
months., why is the shelf life of imported milk so long?a senior imported milk distributor introduced: "First of all, imported milk to go through factory testing, exit testing and customs inspection three procedures, lasted
2 to 3
months." Among them, imported milk by sea transport time is generally
30 to 45
days. That is to say, a bottle of imported milk with a shelf life of
