Tariffs and their functions, ad valorem and specific tariffs, WTO regulations, multilateral trade negotiations, and balance of payment (BOP) contingencies. Essential for Economics and competitive exams.

The concept of tariffs plays a pivotal role in international trade, influencing both government revenue and domestic economic protection. Understanding the functions of tariffs and their types, such as ad valorem and specific tariffs, is essential for students preparing for economics and trade exams. This overview explains how tariffs operate within the WTO framework and their significance in trade policy and economic planning.

Functions and Types of Tariffs in International Trade

• Tariffs serve multiple essential roles in the economy and trade policy.

  At the core, tariffs are designed not only to generate government revenue but also to protect domestic industries and guide economic development by regulating imports.

  • (i) They provide a steady source of revenue for the government.
  • (ii) They protect domestic products from foreign competition by making imported goods more expensive.
  • (iii) They act as instruments of development policy, discouraging non-priority imports like luxury goods and promoting priority imports such as industrial and capital goods.

• Types of Tariffs and Their Mechanisms

  Tariffs can be levied in different ways depending on the country's trade policy and the nature of the product.

  • Ad Valorem Tariff

    This is the most common type of tariff where the duty is calculated as a percentage of the product's price. For example, a 15 percent tariff means the government charges 15% of the value of the imported good. It is the standard method endorsed by the WTO.

    • (i) Reflects the market value of the product.
    • (ii) Easy to administer and adjust according to price changes.
    • (iii) Ensures consistent revenue collection for the government.

  • Specific Tariff

    In this system, the tariff is a fixed amount per unit of the product, such as Rupees 10 per kilogram. Although less common than ad valorem tariffs, it can target specific goods for regulatory or protective purposes.

    • (a) Provides predictability in revenue for specific quantities.
    • (b) Can be used strategically to influence import behavior.
    • (c) Historically less favored in international trade agreements.

  • Tariff Reductions and WTO Standards

    Over the GATT-WTO rounds, tariffs have generally decreased worldwide, promoting freer trade. Developed countries maintain low average tariffs, around 4%, while developing nations average 27% due to economic and protective needs.

    • Developed countries: Low tariffs overall but retain high duties on goods important to developing countries.
    • Developing countries: Use tariffs as key revenue sources and to manage scarce foreign exchange.
    • Trade policy: High tariffs on luxury imports, low tariffs on essential industrial materials.

  • Bound Tariffs and Multilateral Negotiations

    Countries agree in multilateral trade negotiations (MTN) not to exceed specified tariff limits, called bound tariffs. These set a ceiling, ensuring predictability and fairness in trade relations.

    • (i) Governments can charge lower than bound tariffs but not exceed them without compensation.
    • (ii) Raising tariffs above bound levels requires negotiation and possible compensatory reductions on other products.
    • (iii) Provides a mechanism to balance domestic protection with international trade obligations.

  • Contingency Measures and Protection

    Special situations allow countries to raise tariffs temporarily or limit imports to protect the economy or industry.

    • (a) Safeguards: Protect domestic industries from sudden surges of imports.
    • (b) Balance of Payment (BOP) measures: Manage shortages in foreign exchange and stabilize the economy.

• Importance of Tariffs in Trade and Economic Policy

  Understanding tariffs is crucial for students preparing for economics or international trade exams. They serve as a source of revenue, protect domestic industries, and regulate imports according to national priorities. The rules around bound tariffs and contingency measures highlight the balance between domestic protection and global trade commitments.
