For friends in the United States:Based on the last experience, tariffs are calculated based on the time of flight departure. Until the final policy is announced, our prices remain the same. For customers who place orders between 3.29 and 4.2, if there is a tariff, we will do our best to bear it,If there is a delay, please kindly understand. thank you for your support.Any problem just contact us.whatsapp :+86 19951758841
