so today i called UPS asking how much tax & duty i have to pay for my item

apparently the tax duty and gst are charged for every RM500. So if the item is RM1000, they will charge twice the amount for tax duty n gst

is this normal? the tax n duty is 7% and 13% and then 6% gst. I thought i would only have to pay around RM300 max, but now gone up until RM450+

apparently the seller didnt specify the shipping amount, so custom dept simply added about RM283 shipping cost to the item. The shipping cost was actually only 35 euros, and the item itself is 179 euros. So they calculated again and it goes down to 360+, which is still more than i expected. Already asked them to email me the detailed calculation but still havent got it
