I did email PMK_CSCustomSupervisor@pos.com.my , with my item order shipment(with item name and delivery address) and packing list.
Then, pos laju klia did contact me and tell me about the charges things.

So...I really not sure if this is the correct process as i didnt get any email respond from the custom side before pos laju klia contacted me.

I guess you just need to keep track your parcel until it said held by custom and need to call them like my screenshot (or they will call you, after few days)

and... sorry for late respond XD

At the end pos laju help me settle import tax and i went to pos laju sevice center to settle off the taxes and service charges.

I bought 3x figuring from japan which cost around 900.

I you want your parcel fast then u better go self collect at pos cargo klia (not inside klia airport). Which is a bit far for me so i decided seek pos laju help on my case

I cant answer your question as i call and went to pos laju center, no one able to help. They only told me to contact custom. So i emailed details to custom.

I not sure if custom pass my parcel to pos laju after received my email because i didnt get any respond from custom and they didnt even answer my call...
So...i got no choice but only to wait for their phone call.......

i did tell custom during the call but she seem not really understand it.
so i did sent all details like the name, type and price, shipping fee lor.
u try to call custom during office hour see how they advise you.
i believe this is case by case basic la. some need to open it on the spot. i suggest you to call custom and seek help / advise next course of action.

no leh. just start with a blank email.

depend. usually take few working days.
my case, email sent on 26sept , received call on 28sept to notify parcel will send to Klang pos laju about 3 working days later. also will inform you how much custom charged (if any) and pos laju service fee.
if i recall correctly, Klang pos laju officer did called me on 4oct morning said parcel arrived and ask me go collect + make payment. rmb ask that to bring along. i rmb IC only... not sure still same or not.

28th sept was custom.
