From July 1, 2021, the EU will amend the relevant tax laws for products sold to EU member states. For products with a value of fewer than 150 Euros sent from China to EU countries, we will use IOSS for customs clearance. There is no need to pay taxes and fees during delivery, and customs clearance and delivery are faster. Orders sent from China to EU countries are worth more than 150 euros and are subject to import value-added tax and customs duties. This requires buyers to use their own VAT to clear customs and pay import VAT and customs duties. Shipments from EU countries are not subject to import VAT. This tax issue only applies to shipments from China to EU countries. For tax inquiries in other countries, please contact email: email@example.com
