The European Union (EU) is the world’s largest trading unit known as a customs union. There are currently fifteen member countries. In a customs union, internal tariffs are eliminated and the member countries form a single customs territory with a common external tariff. For example, once the good enters France or any EU member country and the common tariff is paid the good is free to circulate within all the EU countries. This is the freedom to move goods from country to country. This trade arrangement requires a lot of coordination from EU member countries. Since there is only one common external tariff, every country has to agree on what that tariff will be. This is not an easy process, and the application of trade solutions such as anti-dumping and countervailing duties have to be coordinated.
歐洲同盟（歐盟）就是關稅同盟，是世界上的貿易單位。目前它有15個成員國。關稅同盟中，其內部關稅免除，成員國建立一個對于共同的外來關稅的單一的海關邊界。例如，貨物一旦進入法國或其他歐盟成員國，交納一次統(tǒng)一的關稅，而在所有歐盟國家中自由流通。這是國家與國家之間貨物流通的特權。這種貿易協(xié)定要求歐盟成員國之間進行許多的合作。由于只有一個共同對外關稅，每個國家必須在關稅上達成統(tǒng)一。這個過程并不容易，而且像反傾銷和補償關稅這種貿易方案的運用也要調整。
