I have a slight confusion regarding the freight rates. Is the rate not as per the shipping fee I paid? I paid around RM70 for DHL shipping from Japan but my freight charge was stated RM321.91, causing the total value to exceed RM500 and I have to pay duty. I checked with DHL and they informed me this is according to IATA rates. I however have never faced any IATA rates problem with EMS or regular airmail before.

Appreciate it if anyone can explain this situation to me.
