usd300 > rm500 sure kena...
try check at tariff.customs.gov.my

owh mai, you're in deep shit, well i've been in yours before,

you sure need AP permit and pay taxes, estimation spending around RM300 ~ +

I don't think mobile phone cases need permit...
DHL helped me cleared the detained shipments a few times... End up paying custom duty fees only with 2~3 (1 working day) days of delay. so fast and efficient.

mobile phone case should be no tax, u can just go to kastam ask them why? sometimes they just want to know wat's inside because ur box is big and heavy maybe and also if the box dont have any declaration, kastam always tahan that, mine always kene, but I just go there and open infornt of the officer, show the invoice, setel. no worry, just go there and ask them. if they want to tax u, then ask them to show under what tariff code.

easier, u just go to the kastam... and clarify to them what actually u are bring in. dont worry, the kastam officers r friendly, from my experience la. just open the box infront of them (eventhou they already open it) and tell them wat's inside and show them how do u use it. that's it. if u j ust contact them tru phone, fax, i think it lotsa difficult to both party to understand.

hey there... sorry i couldn't find the tariff codes i think i had thrown away the boxes together with the declaration forms.
