They are operated by the post office all over the world. EMS Express can be tracked on EMS website (China Post Office) and your local post office. Air Register Mail can be tracked by your local post office. Both need your signature to accept.If you need the track number, please send an e-mail or leave a message to us for acquisition.We can also use other express shipping, such as: UPS, DHL, FedEx and TNT etc, while the cost will be higher. You shall contact us first if you need mentioned above service.Shipping insurance is optional and it is up to the customer.If you need to know the detailed shipping cost, please send us message.Shipping PeriodGenerally speaking, Chinese EMS Express takes about 2 to 4 days from China to Asia countries, about 3 to 6 days to Australia, USA or Canada, about 5 to 10 days to Euro continent and about 6-12 days to South America etc. Be noticed that some countries or places may take longer time.The shipping period may happen to some exception because of the custom check and post office neglect. You can contact us if you don?t have it in regular days. We will firstly check it with track number. If it doesn?t work we will send the track application in paper to the post office, which will take several days to acquire the reply. That is the normal track progress set by the Chinese Post Office.Compared with Hong Kong Post Service, Chinese Chinese Air Register Mail which is cheaper and slower than EMS Express is strange for the shipping period and delivery (mainly because of the international flight). Sometimes fast in 7 days, and sometimes later than 21 days. Moreover it has little and poor information about the shipping condition. We have many cases that even customer gets the item, the system of the post office still tells that it was just sent from China several days ago. In that case, we sincerely hope customers can keep a little more patience for the potential delay, since we can?t control the shipping speed of post office and custom release.
