A Common External Tariff (CET) is a uniform tariff rate adopted by a group of countries on imports from non-member countries. When countries form a customs union, they agree to apply the same external tariff rates to goods coming from outside the union. This means that regardless of which member country imports a product, the same tariff rate is applied.

Key Features of a Common External Tariff
1. Uniform Tariff Rates:
- Consistency: All member countries of the customs union apply the same tariff rates on goods imported from non-member countries.
- Simplification: This simplifies trade regulations within the union, making it easier for businesses to operate.
2. Trade Protection:
- Protectionism: The CET protects the industries of the member countries from external competition by imposing tariffs on foreign goods.
- Revenue Generation: Tariffs collected under the CET contribute to government revenues.
3. Economic Integration:
- Customs Union: A CET is a key feature of a customs union, promoting deeper economic integration among member countries.
- Harmonization: It requires the harmonization of trade policies, leading to more coordinated economic strategies.
Importance of a Common External Tariff
1. Promotes Regional Trade:
- Free Trade Within the Union: By adopting a CET, member countries can eliminate internal tariffs and trade freely with each other.
- Economic Growth: Increased regional trade can lead to economic growth and development for member countries.
2. Simplifies Trade Policies:
- Streamlined Regulations: A CET simplifies the trade policies for businesses, reducing the complexity of dealing with different tariff rates in each country.
- Predictability: Uniform tariffs provide predictability and stability for businesses engaged in international trade.
3. Strengthens Bargaining Power:
- Collective Negotiations: Member countries can negotiate trade agreements with non-member countries as a bloc, giving them greater bargaining power.
- Influence on Global Trade: A customs union with a CET can have a significant influence on global trade policies and negotiations.
Example of a Common External Tariff
The European Union (EU):
- Customs Union: The EU is one of the most well-known examples of a customs union with a CET. All EU member states apply the same external tariff rates to goods imported from outside the EU.
- Trade Benefits: This arrangement allows for free trade within the EU, promoting economic integration and cooperation among member states.
- Impact on Non-EU Countries: Non-EU countries must comply with the CET when exporting goods to the EU, influencing their trade strategies and market access.
How a Common External Tariff Works
1. Implementation:
- Agreements: Member countries of a customs union negotiate and agree on the tariff rates to be applied to imports from non-member countries.
- Legislation: Each member country enacts legislation to enforce the CET, ensuring uniform application of the tariff rates.
2. Customs Procedures:
- Border Control: Customs authorities at the borders of member countries apply the CET to imported goods, collecting the appropriate tariffs.
- Compliance: Businesses importing goods into the customs union must comply with the CET and pay the required tariffs.
3. Economic Effects:
- Trade Diversion: The CET can lead to trade diversion, where member countries import goods from within the union rather than from non-member countries.
- Price Impact: The imposition of tariffs can increase the prices of imported goods, affecting consumers and businesses within the union.
Benefits and Challenges of a Common External Tariff
Benefits:
- Economic Integration: A CET fosters economic integration and cooperation among member countries, leading to regional stability and growth.
- Simplified Trade: Uniform tariffs simplify trade regulations, making it easier for businesses to operate within the customs union.
- Bargaining Power: Collective negotiation of trade agreements enhances the bargaining power of member countries on the global stage.
Challenges:
- Loss of Autonomy: Member countries may lose some autonomy over their trade policies, as they must adhere to the CET.
- Adjustment Costs: Industries within the customs union may face adjustment costs as they adapt to the CET and increased competition.
- External Relations: Non-member countries may face barriers to market access, affecting their trade relations with the customs union.
Conclusion
A Common External Tariff (CET) is a crucial component of a customs union, promoting economic integration, simplifying trade regulations, and enhancing the collective bargaining power of member countries. By understanding the principles and implications of a CET, businesses and policymakers can navigate the complexities of international trade more effectively.
