If you disagree with the amount of custom charge by your country's custom.
First of all, please ask your country's custom to explain the basis for the amount of custom charge.
We will not assist you in any way in calculating the amount of tax due in your country.
After you ask to custom, If you find that the commercial invoice we made was incorrect, we will propose a solution.
To do so, you will need to provide us with proof that our invoice was wrong.
However, commercial invoices are automatically generated, so there is no possibility of mistakes.
We would like to inform you in advance that mistakes will not occur unless there are special circumstances.
Also, it almost never happens that customs makes mistake in custom charge,
but we have had experiences in the past the customs did in in currency conversion.
In that case, we will not assist resolving that issue in any way.
Basically, the custom charge on your personal imports are the matter between you and your country's customs.
We will not respond to your inquiry unless our commercial invoice was incorrect.
Thank you for your understanding.
