We normally ship orders using DDP (Delivered Duty Paid), which means no additional shipping charges, customs duties, or import taxes are required from the recipient under normal circumstances.

However, additional surcharges may apply to certain remote areas or destinations subject to special shipping restrictions or weight limitations.

If you choose DHL as your shipping method, additional shipping charges may apply. In this case, the recipient is responsible for customs clearance and payment of any applicable duties and taxes.
