The customer is considered the importer of record and, as such, is responsible for paying the import fees and complying with all laws and regulations of the country into which the product is being delivered. Import fees will be collected by the carrier (DHL or Fedex), in most cases prior to or at the time of delivery. Customs policies vary widely from country to country, so you should contact your local customs office for further information.
Please note that customs offices in some countries require the importer (customer) to provide a CPF, Tax ID, or other Unique Identification number for the recipient. To insure prompt delivery, this information can be added to the import documents by putting it in the "Company" line of the shipping address.
