EMS Express Airmail is speeding up! According to previous package delivery successfully  :

Airmail EMS/HongKong Post cost 5-7work days to USA, Canada, Australia, West Europe, and only 3-5 days to UAE.  

But will cost longer if in East Europe, Middle East, West Asia, South America and Africa.

How long about the remote area or undeveloped area? it's dependens on your local post office and how may Airlines possbile every days to your international Airport.

Import Note:

orders is few days before or after the  Festival Holiday would be longer, especially around China Spring Festival Holiday will cost much longer  ! 

so as to shipment around the Festival promotion days will nee longer shipping time than usual

Please kindly be noted this is only the previous experience for your reference, sometimes maybe longer some time maybe few days, EMS is belong to nationa post express service, it's unlike DHL/UPS. the package will be processing by two country's national post service. destination customs will also influence the delivery time.

DHL generally cost about 3-5 work days.
