If you buy a product and ship it to any EU country then you will not incur any additional custom fees (you will however have to pay VAT on top of the net amount if you aren’t a business with a valid European Tax Identification Number). If you have a valid European Tax Identification Number, the entire purchase price including the shipping costs will be the net amount.
In the case of shipments to other European countries (the ones that do not belong to the EU), the shipment will go through customs and therefore customs and other tax charges will be applicable. They will be calculated in accordance with the rates applicable in your country.
If you buy a product outside the European continent, the shipment will also go through customs clearance, and therefore customs and tax charges will be added in accordance with the rates applicable in your country.
US customers may be additionally asked by customs authorities to complete an FDA form. Please bear in mind that the importer (you) is responsible for completing this form.
Each package sent by us outside the EU, in addition to the courier label, has an invoice and a customs clearance card together with a detailed description of the dispatched goods.
