Important: Envistia Mall ships from the United States. When your order arrives in your country, it is considered an import and may be subject to charges collected by your local customs authority — these are not fees charged by Envistia Mall.

Depending on your country, you may be responsible for:

• Import duties or tariffs — set by your country's government, based on the declared value and category of your order
• VAT or import tax — required in many countries, including all European Union member states, regardless of order value (for example, 21% in Spain, 25% in Sweden, 19% in Germany)
• Carrier brokerage or handling fee — some couriers (such as DHL, FedEx, or UPS) charge a separate administrative fee for processing customs clearance on your behalf

These charges are calculated and collected by your country at the time your package clears customs, which is why you may receive a notice or invoice directly from the carrier requesting payment before delivery. This is standard practice for international shipments and is not included in our shipping costs, as these amounts vary by country and are outside of our control.

If you have a question about a specific fee, please contact us — while we can't waive government-imposed taxes, we're happy to review your situation with you.

If your preferred shipping option is not available at checkout, or if you would like to arrange shipment via a different carrier, please contact us.
