Correct Option: C. Promotion of international trade Detailed Explanation: Import duties, also known as tariffs, are taxes imposed by a government on goods and services imported from other countries. The primary purposes of these duties include generating revenue for the government, protecting domestic industries, and conserving foreign exchange earnings. However, they do not promote international trade. Let’s break down each option to understand why C is the correct answer and why the others are not. A. Generation of revenue for government

• Explanation: One of the main purposes of import duties is to generate revenue for the government. When goods are imported, the government collects taxes on these goods, which contributes to its overall budget. This revenue can be used for public services, infrastructure, and other government expenditures.
• Conclusion: This option is correct because generating revenue is a fundamental purpose of imposing import duties.

B. Protection of domestic industries

• Explanation: Import duties are often used to protect domestic industries from foreign competition. By making imported goods more expensive, domestic products become relatively cheaper, encouraging consumers to buy locally produced goods. This protection helps to sustain local jobs and industries that might otherwise struggle against cheaper foreign imports.
• Conclusion: This option is also correct as protecting domestic industries is a key reason for implementing import duties.

C. Promotion of international trade

• Explanation: Import duties do not promote international trade; in fact, they can hinder it. When tariffs are imposed, they increase the cost of imported goods, which can lead to a decrease in the volume of trade between countries. High tariffs can create trade barriers, making it more difficult for countries to engage in free trade. Instead of promoting trade, import duties often lead to trade disputes and retaliatory measures from other countries.
• Conclusion: This option is correct because the imposition of import duties typically restricts rather than promotes international trade.

D. Conservation of foreign exchange earnings

• Explanation: Import duties can help conserve foreign exchange earnings by discouraging excessive imports. When a country imposes tariffs, it makes imported goods more expensive, which can lead to a reduction in the quantity of imports. This helps to maintain a favorable balance of payments and ensures that the country does not deplete its foreign exchange reserves too quickly.
• Conclusion: This option is correct as conserving foreign exchange earnings is a valid purpose of import duties.

Summary of Why Other Options Are Incorrect or Weaker:

• Option A is correct because generating revenue is a primary function of import duties.
• Option B is correct as import duties are designed to protect domestic industries from foreign competition.
• Option D is correct because import duties can help conserve foreign exchange by reducing the volume of imports.
• Option C is the only option that does not align with the purposes of import duties, as they typically restrict rather than promote international trade.

Common Pitfalls:

• Students may confuse the protective nature of tariffs with the idea that they promote trade. It’s essential to understand that while tariffs can protect local industries, they do so at the expense of international trade.
• Misunderstanding the economic implications of tariffs can lead to incorrect conclusions about their overall impact on the economy.

Revision Summary:

• Import duties generate revenue for the government and protect domestic industries.
• They can conserve foreign exchange by reducing imports.
• Import duties do not promote international trade; they often restrict it.
• Understanding the economic implications of tariffs is crucial for grasping their role in international trade.
