Import taxes and custom duties on supplements?

Does anyone know if there are any import taxes / duties or regulations if you were to order vitamins online and have them shipped to Taiwan? If so, what are they?

If you are shipping from online you have most likely a postal shipment so you check with the post office.

Why ship in vitamins when you can buy them here. Or just eat healthily and you wont need vitamin supplements.

One could spend several hours each day shopping around for fine produce, or one could supplement one’s diet with vitamins. I have tried both, and the mixture of the two seems to gain the most benefit.
Costco here in Taiwan has plenty of vitamins. I wouldn’t import them, as the duty rate is bound to be high. Forget the post office, they have no clue about the Harmonized Tariff.
