Hi, I would like to order clothes in bulk(20 units ++) from China. If the seller send me through EMS, will I get charged for tax by Malaysia kastam ? and will I get any unwanted troubles like kastam hold my item and this and that?

As far as I know, clothes will be taxed.

it depends..i heard from many clothes seller complaining the kastam...
they doing bulk order from china and sometimes their order may reach 100+ pcs(kastam didnt kacau at all and no tax also)....
but sometimes they bulk order 20-30+ pcs,kastam hold their stuff and ask them to pay taxes....
so my conclusion is kastam do their work based on their mood....u need some luck though:)
I myself imported alot of goods from China(tattoo machine,ink,shirts,phones etc....) so far not being taxed yet because i didnt use EMS....i use Sea Shipment...
If u need this service,i can introduce u the agent i am using now...good service and cheap price:)

ooh.. EMS is air shipment right? so using Sea shipment wont be taxed, but air shipment will be taxed?

yes u are right:)
