For now we only ship to Slovenia and Croatia, both of them are in EU, so no, you don’t have to pay any extra tax or duty.
FYI: International shipments (outside EU Zone) are subject to import fees, duties and taxes, which are levied once a shipment reaches their country, in addition to the brokerage fees / custom clearance charges which may be imposed by the carrier. These charges must be paid by yourself. We have no control over these charges. If an international shipment is refused and / or returned, any taxes, duties, custom fees, brokerage fees or shipping charges incurred from this return, will be the responsibility of the customer.
