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. ' I$ J N* u4 ]I 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. u K6 J3 G$ G' B4 I T" nBest wishes
