There are three different shipping types for international mail. The customers can choose their option depending on the rates and the number of delivery days that work out for them.
Express Mail Service (EMS)
This service holds the top priority as far as international mail is concerned. All the posts are delivered within two to four days anywhere around the world.
Airmail
The deliveries are made within 3 to 6 days. However, the charges are relatively higher since the medium of transport is by air.
Economy Air (SAL)
The items are transported by air but they are less prioritized than the air mail. So the advantage is that the service is faster when compared to surface mail but costs are lower when compared to air mail.
Surface mail
The deliveries can take anywhere between 1 to 3 months and so the rates are reasonable as well.
