When ordering, you're the importer of record on your order and you must comply with all laws and regulations of the destination country. If you are outside of the USA, you may be subject to import taxes, customs duties and fees levied by the destination country that you will have to pay for once the shipment reaches you. These additional charges for customs clearances must be paid by the recipient of the order.
As policies range from country to country, you should contact your local customs office for more information. Many times the delays in international shipments are due to the customs clearance process.
