Sorry everyone, I did not come to this website for quite a while. / c: o; D! N8 i, c7 ~Now I am applying the established license for importing the face mask. This is the government requirement for importing class 1 medical materials, which including face mask. This was a surprise for me. I have discussed that with several government departments for the license and finally found a clue. The whole process would take 1 to 2 months. That means my masks ( I have already paid money) have to be stored in a Chinese factory until I obtain the license. 9 R. X: n6 o. g( d5 j( T. a7 X3 yI am so sorry for this unexpected process. If anyone needs the face mask in the following one month, please try to buy them in a drugstore or other places. 2 l; o* x$ X+ B' g6 }- m( ABest wishes
