If a customer complains about customs issues or import fees, duties, or tariffs you can answer with the following facts:

• As a business based in the USA, we have no control over foreign countries customs and how they handle, hold, or tax international shipments. 
• We only charge what is costs us to ship an order, and if customs decides to apply further charges or holds, unfortunately we have no authority to challenge this. 
• In such cases, we would suggest making a call or reaching out to customs beforehand, and inquiring if they are able to give you an idea of what to expect for future orders.
