The customs and tax affairs of European countries are relatively complex, and the customs requirements and import VAT policies of different countries within the EU vary, especially for non EU domestic importers. The requirements are more complex, and an oversight may cause customs to withhold/return goods or have a negative impact on customer e-commerce platform accounts. Since 2018, one-stop logistics has been adhering to the concept of compliant customs clearance, providing customers with European customs and tax compliance solutions. In response to constantly changing European customs and tax policies, such as the implementation of German packaging laws, changes after Brexit in the UK, EU e-commerce tax reform, and France's deferred policies, we are always interpreting policy changes for customers in the first place and providing corresponding solutions.
