Hi. Im planning to buy Spigen iphone case from amazon which cost around 18 dollars. i checked the shipping will cost around 15 dollars, and this amount is only for global shipping fee and it shows 0 for estimated import fees deposit.

So my question is will it be taxed upon import? if i buy more units like 10 of them, will it be taxed as well? if it is taxed how much will it be roughly?

thanks
