Why can't you tell me exactly the amount I must pay for the import fee?

It is hard to tell precisely, as we are based in the EU and do not know the laws of your country. Import taxes can vary by the country where the product is manufactured, product type and fabric, and your country’s de minimis value. 

Every country has an individual tax rate. Tax rates may vary by state. Currency exchange changes every day. Countries implement new rules and laws. Some countries add a government fee on all goods from abroad, which may rise by the end of the year for various reasons. Therefore, expect to pay the max %, but hope for the lowest fees. Most of our customers report usually paying something in between the % stated in our table.
