Hi, I would like to share my experience of importing supplements through courier service, the vendor is Puritan Pride and I m using DHL (not express)
. They are total of 5 orders make since mar 2013 and for each order the total amt is less than RM 500 and the total bottles per order is from 15 to 33 (max is 9 bottles per 1 product). Fortunately my orders is never been confiscated by MOH or Kastam.
Normally I received my parcel after 14 to 21 days from confirmed shipment date.

Anyway I never order supplement from IHerb

JutaMind,
How many botol of supplements in your last order via DHL ?

if I want to order 4 bottles of different product of supplement from IHerb via DHL, don't know whether it will confiscate by kastam or not.
Normal Mail is take too long to reach here
