How international orders work
All international orders are shipped on DAP (Delivered At Place) terms. This means:
- The price you pay at checkout covers your goods and international shipping only.

- Import VAT (value-added tax),
- Tariffs or customs duties (import taxes based on product category and value), and
- Handling or clearance fees from the courier.
These charges are set by your country’s customs authority and are payable by you before delivery.
You’ll be contacted directly by DHL with a secure link to pay any applicable charges. Once cleared, your parcel will be released and delivered promptly.
Estimated delivery times (after dispatch)
- European Union: approximately 2–5 working days
- Rest of World: approximately 5–7 working days
Customs processing times vary by country and may extend delivery slightly.
If import charges, tariffs, or duties are not paid
If local charges are unpaid or delivery is refused, the shipment will be returned to us. In this case, we will refund your order minus the outbound shipping cost and any return or customs fees billed to us by the carrier.
Estimating import costs
Import VAT and duty rates vary by country. You can check estimated import taxes and tariffs by contacting your local customs authority or using your government’s online import calculator.
