CET: Common External Tariff

An overview of the Common External Tariff (CET), its historical context, types, key events, explanations, importance, applicability, examples, and related concepts in trade economics.

Historical Context

The concept of a Common External Tariff (CET) has its roots in economic agreements that aim to promote free trade among member countries while imposing a unified tariff on imports from non-member countries. One of the most prominent examples is the European Union (EU), which has implemented a CET since the inception of its customs union in 1968. The goal was to harmonize tariffs to eliminate trade barriers within the union and to present a uniform tariff policy to external countries.

Types/Categories of CET

1. Customs Union CET:

   • Implemented by a group of countries forming a customs union.
   • Example: The EU CET.

2. Regional Trade Agreements CET:

   • Adopted by regional trade agreements among countries not necessarily forming a customs union.
   • Example: West African Economic and Monetary Union (WAEMU) CET.

3. Sector-Specific CET:

   • Applied to specific sectors like agriculture or technology.
   • Example: Common agricultural policy in the EU which includes sector-specific tariffs.

Key Events

• 1968: Implementation of the CET by the European Economic Community (EEC).
• 2000: Establishment of the CET in the East African Community (EAC).
• 2015: African Union (AU) endorses the CET for the African Continental Free Trade Area (AfCFTA).

Detailed Explanation

The CET is designed to simplify trade by ensuring that all member countries of a customs union apply the same tariffs on imports from non-member countries. This eliminates the need for customs checks between member states and promotes efficiency and economic integration.

Mathematical Model of CET

The tariff \(T_c\) applied by a customs union is given by:

$$ T_c = \frac{\sum_{i=1}^{n} T_i}{n} $$

where \(T_i\) is the individual tariff rate of country \(i\), and \(n\) is the number of member countries.
