International shipments may be subject to duties and taxes depending on the item being shipped and the countries of the sending and receiving parties. Payment for all duties and taxes are the responsibility of the buyer or receiving party at the time of delivery.

If the seller has over-valued your purchase in the customs declaration (i.e. set the value of the item as a higher amount than you purchased it for) and you are required to pay the difference to release the parcel, you should contact the seller to have them resolve the issue before deciding to accept or refuse the package. If you accept the package, you may not be eligible for reimbursement for the higher cost.
