Shipping Notice for USA Customers UPDATED 16th Jan., 2026
1. US import tariffs (duties) must be paid before the goods enter the United States. These charges are not refunded by the US government. Please make sure that the tariffs are paid in advance.
2. Due to recent updates in the tariff policy by the U.S. government, shipments from the UK to the USA may incur duties or import taxes, ranging from 20% to 40% of the total value. As a result, we will mark most items at 50% off of the original order value. In order to minimize the import duty charges, we will take steps that we hope will not cause any issues for you.
