When importing goods from one country to another, import duties are often levied on the goods. These duties are imposed by the customs authorities of the importing country and are meant to protect the local economy and industries from foreign competition. Understanding the import duty structure can help importers and exporters plan and budget for their international trade activities.

Import duties can be calculated in different ways, but generally, they are based on the value of the imported goods, the quantity or weight of the goods, or a combination of both. The rate of duty can also vary depending on the type of goods being imported, their country of origin, and the trade agreements between the importing and exporting countries.

Here are some examples of the import duty structure in different regions of the world:

1. Europe: The European Union (EU) operates a single market with a common customs tariff for all member states. The EU’s import duty rates are based on the Harmonized System (HS) of classification, which is a standardized system used to classify goods for customs purposes. The duty rates can vary from zero to several hundred percent, depending on the type of goods being imported.
2. North America: The United States operates on an ad valorem system, where the duty rate is based on the value of the imported goods. The duty rates can vary from zero to several percent, depending on the type of goods being imported. The North American Free Trade Agreement (NAFTA) also allows for duty-free trade between the United States, Canada, and Mexico for certain goods.
3. Asia: In Asia, import duties vary widely by country. For example, China’s import duty rates are based on the HS system and can range from zero to 50 percent, depending on the type of goods being imported. Japan also uses the HS system and has a relatively low average duty rate of around 2.5 percent.
4. Africa: Africa has a complex and fragmented import duty structure, with duties varying by country and region. The African Continental Free Trade Area (AfCFTA) aims to create a single market for goods and services across the continent and to eliminate import duties on 97 percent of all goods traded within the region.

The worldwide customs import duty structure is crucial for any business engaged in international trade. Importers and exporters should research the import duty rates for the countries they are dealing with and factor them into their pricing and budgeting. They should also stay up-to-date on any changes or updates to the import duty structure in their target markets to ensure compliance with local regulations.
