Form E....How to Use?

[inquisitive lobster]

Hi There,

First off I'd like to thank you for taking the time to read this :-)

Okay, so I read that in order to avoid Import Duties between ASEAN countries like China and Thailand, you must have the Form E.

My question is how exactly do you use it........

For example, if you were to order a package like electronic parts (lets say a camera system for example) from China using DHL (to be imported to Thailand) and the supplier already sent you the original documents such as the Packing List, Commercial Invoice and Form E, how do you use them?

I would prefer to avoid having to go to the airport to clear the package myself especially as I have already paid for home delivery.

Anyone knows how to use this?
