Hi...newb here and ive been reading thru several pages but i need confirmation on few things so pls help me out

If i were to purchase an electronic item such as a cellphone worth above rm 500 and have it delivered to me via DHL and not to have it held by the customs....can i apply for AP manually and pay the tax beforehand, or does DHL handles all these stuffs for me and just backcharge me the tax amount?

As for the tax...10% of the cost of purchase + shipment is all i need to pay for the this type of goods?

Pls enlighten me!
