1. Definition
A Customs Union is an agreement between two or more countries to remove trade barriers, such as tariffs and import quotas, on goods traded between them while applying a common external tariff to goods imported from non-member countries. It is a form of economic integration designed to promote trade and economic cooperation among member states.
Unlike a free trade area, which only eliminates tariffs among members, a customs union standardizes external trade policies. Member states surrender a portion of their trade policy independence to create a unified approach towards external markets.
2. Key Characteristics of a Customs Union
-
Elimination of Internal Tariffs:
Goods can move freely between member states without additional tariffs or quotas. -
Common External Tariff (CET):
All member states apply the same tariff rates on imports from non-member countries, ensuring uniformity in external trade relations. -
Economic Cooperation:
Member states often coordinate policies on trade, customs procedures, and sometimes even broader economic matters to enhance the union's efficiency.
3. Examples of Customs Unions
-
