Customs fees and import duties are the responsibility of the customer (even if you refuse a shipment upon delivery). We do not collect the VAT, duties, and/or taxes at the time of sale and cannot predict what your particular charges may be.
If your order does require these additional charges, they must be paid by you in order for your package to clear customs. We recommend checking your country's custom import duties webpage for an estimate of what fees you may be required to pay.
