Have you ever wondered how to accurately calculate customs duties for your imports? This article aims to provide you with a clear and detailed understanding of the methods for calculating customs duties, explaining the steps and key elements to consider.

Mastering this subject is essential to avoid financial surprises and optimize your costs.

Let’s dive into the details to demystify this complex process.

  • Understanding customs value and methods of calculating fees
  • Gaining in-depth knowledge of customs duties and VAT

Three factors have to consider for duty calculation

Calculating customs duties is based on several key criteria: customs value (value of the goods plus transportation and insurance costs), customs duties (a percentage determined by the tariff code of the goods), and any additional taxes like VAT.

For example, for a product worth €1000, with customs duties at 10%, the total cost would be €1100 plus VAT. 

Adhering to the criteria of customs value is essential for an accurate assessment of taxes.

according to French Customs.

Customs value

The customs value is the basis on which customs duties are calculated. It includes the price of the goods, transportation costs to the EU border, and insurance costs. 

For example, if goods cost €2000 with transportation costs of €200 and insurance of €50, the customs value would be €2250. 

This value is crucial because it determines the amount of customs duties and VAT. 

Customs duties by country

Customs duties vary depending on trade agreements between countries. For example, duties on a product imported from the United States might be 5%, while the same product from China could be subject to 12%. 

Here is a comparative table to illustrate:

CountryCustoms Duties (%)
United States5 %
China12 %
Japan4 %
India10 %

These variations are determined by bilateral trade relations and free trade agreements. Statistics show that customs duties for countries with which the EU has free trade agreements are generally lower.

Additional taxes such as VAT

In addition to customs duties, additional taxes like VAT may apply when importing goods. In France, VAT is often 20% and is calculated on the customs value plus customs duties. 

For example, for goods with a customs value of €2250 and customs duties of €225, the VAT calculation base would be €2475. The VAT due would then be €495. 

These additional taxes are essential to anticipate to avoid financial surprises.
