Attention USA customers. With the suspension of the US de minimis import exception, all shipments, regardless of origin, transportation mode, or entry method, now require formal customs entry and the payment of all applicable duties, taxes, and fees. Our shipping cost already prices in The cost of tariffs and clearing fees. That is why the shipping quote is higher than expected. Tariffs and clearing fees are included. Our American customers have always been an integral support to our business, so we thank you for your continued support and understanding during this transition.
