It depends on the total amount of your order and which country you are from. Every country has a minimum threshold for paying import duties and taxes, you can Google to find what's the threshold in your country, the threshold is $200 in US.
If your order doesn't exceeds the threshold, then you don't need to pay any import duties and taxes.
If your order exceeds the threshold, then in most cases you need to pay a small amount of import duties and taxes when your order arrives. The good news for retailers is that the import tax can be deducted when you start to sell the products. Another thing is that import tax is charge based on the total amount on the invoice, so if you would like to pay less tax by putting a smaller amount on the invoice, please contact us email@example.com
