Export Duty is a tax imposed by a government on goods and services that are sent out of the country. This tax is usually calculated as a percentage of the value of the exported items. The purpose of export duties is to generate revenue for the government and to regulate the flow of certain goods, which can help protect local industries. Countries may impose export duties on specific products, such as raw materials or agricultural products, to encourage domestic processing or to ensure that local supply meets demand. Export duties can also be used as a tool in international trade negotiations, influencing trade relationships between nations.
