We use UPS/DP/DHL/UPS and other local logistics companies for delivery services. You can check your express logistics status through the express service company's official website (you can see the updated logistics tracking number in your personal Exway account). For the USA, the taxes are prepaid. If the logistics contractor loses your package, please get in touch with us（usa@exwayboard.com). Note: When you place an order, be sure to enter the correct name, address, and contact information so that we can deliver your items successfully.
