EMS has big problems recently if the parcel is more than 5kgs. Bejing customs checks it very seriously. Now many EMS parcels were sent back from Beijing customs, which wastes us much time.
So, if the material is urgent for you, we suggest you use DHL. DHL can promise the transportation time and no any customs problem in China.
If you need any support, please contact us freely.
