Customs duty is a tax levied on imports (and, sometimes, on exports) by the customs authorities of a country to raise state revenue, and/or to protect domestic industries from more efficient or predatory competitors from abroad.
Customs duty is required in some countries occasionally.
a. Once you are informed to pay the duty fee (and if it is less than US$30), please pay it. Then send the invoice copy to email@example.com, and we will reimburse you.
b. If the duty fee is more than US$30 or higher than your order amount, please contact us first, so we will resend you a new package as what you had ordered.
Note: We won't reimburse for customs duty paid by customers without Zeelool's confirmation.
