Import duties: calculate and manage your landed cost
The product deal is done, but what are the real costs when your container arrives in Rotterdam? Uncertainty about the total landed cost is fatal to your margin. Import duties, transport costs, and political tensions turn budgeting into a gamble. In this article, you'll learn the exact formula to calculate import duties, understand the risks of tariffs from China or the US, and see how the right freight forwarder and Incoterms help you regain full control and protect your profit.

You've closed the perfect product deal in China. The down payment is made. And then comes the question that keeps every importer awake at night: what costs will actually be added once that container enters the port of Rotterdam?
That uncertainty is fatal to your margin. Political tensions between the EU, China, and the US turn budgeting into a gamble. A tweet from Washington or a decision in Brussels can overturn your landed cost overnight. Stop gambling. This isn't an academic paper; it's a practical toolkit. Let's open up the black box of import duties so you can take back the reins.
How to calculate your own import duties
When your shipment crosses the EU border, customs looks at two things: the commodity code and the value. The calculation is a piece of cake, provided you use the right ingredients.
Step 1: Find the correct commodity code (TARIC code)
Every product has a unique numerical code that determines the import duty percentage. A shipment of cotton T-shirts (code 6109.10) is subject to a 12% import duty, while sports shoes (code 6404.11) hit 17%. The wrong code, and thus an incorrect import duty, can cost you thousands of euros or lead to fines and delays. The single source of truth is the official Access2Markets-database of the European Commission. Alternatively, you can use the website of the Dutch customs or Tax Authorities (Belastingdienst) for the correct HS code in the
Netherlands. Always double-check your code there.
Step 2: Determine the customs value (the most common mistake)
The biggest mistake importers make? Calculating import duties based on the product price alone. Customs uses the customs value, and the formula is crucial:
Customs Value = Product Price + Transportation Costs + Insurance Costs (up to the EU border)
Expensive sea freight, therefore, doesn't just mean higher transport costs, but also extra import duties on those same costs.
A calculation example: You are importing 100 gadgets from China.
- Product Value: €1,000
- Transport & Insurance: €220
- Import Duty (according to TARIC code): 1.7%
The calculation:
- Customs Value: €1,000 + €220 = €1,220
- Import Duties: 1.7% of €1,220 = €20.74
- Taxable base for VAT: €1,220 + €20.74 = €1,240.74
- VAT (21%): 21% of €1,240.74 = €260.56
The total customs costs here add up to €281.30 for your shipment. That's 28% on top of the product value.

The impact of politics on your import duties
That 1.7% is a standard rate. Political reality can suddenly triple this
percentage.
- China: The EU increasingly sees China as a 'strategic competitor' and uses tariffs as a weapon. The threat of a higher import duty on Chinese goods is real; the extra levies on electric cars in 2024 were not an incident, but a blueprint. As an importer, you must factor in a political risk premium.
- US: Without a free trade agreement, standard tariffs apply. More importantly, there's the threat of an unexpected US import duty on specific products as part of retaliatory actions. Think of the sudden steel tariffs.These 'tit-for-tat' tariffs can appear out of nowhere and undermine your business model.
Save on import duties: 2 strategic choices
You can't change world politics, but you can change how you deal with it. It comes down to two proactive choices.
1. Choose a 100% transparent freight forwarder
A good freight forwarder doesn't hide behind vague all-in prices. On our digital platform, you see every cost item immediately, from freight to insurance and even our margin. Import duties and VAT can only be calculated upon arrival, but our customs agent prepares the declaration in a timely manner. This way, we always share the final calculation with you before delivery. No surprises afterward.
2. Take control with the right Incoterms
Many importers opt for CIF (Cost, Insurance, Freight), where the supplier arranges transport. It seems convenient, but you have zero influence over the often-inflated transport costs on the invoice. By choosing FOB (Free on Board), you take matters into your own hands. You choose the carrier and pay the actual costs. This not only gives you more control but almost always leads to lower total landed costs.
Turn import duties into a strategic advantage
Import duties are not a fixed cost. They are a dynamic cost item that you must manage. By understanding the calculation, grasping the political landscape, and choosing a partner like Cargoplot that offers full transparency, you turn uncertainty into a manageable factor. You turn a risk into a strategic advantage.

Frequently Asked Questions about import duties
How do I calculate import duties?
You calculate import duties by applying the correct percentage (based on the TARIC commodity code) to the customs value. The customs value is the sum of your product price, transportation costs, and insurance costs up to the EU border.
What is the customs value?
The customs value is the total value of your shipment on which customs calculates the import duties. It is therefore more than just the price of the products; it includes all costs to get the goods to the EU border, such as transport and insurance.
Where can I find the correct commodity code and the percentage for an import Duty?
The only official and reliable source for commodity codes (TARIC codes) and their corresponding import duty percentages is the Access2Markets database of the European Commission or the customs website at https://tarief.douane.nl/.
How does politics influence import duties from China and the US?
Political tensions can lead to sudden and additional import duties. The EU may impose a higher import duty on China due to strategic competition. An import duty from the US can be unexpectedly implemented as a retaliatory measure in a trade conflict. This makes factoring in a political risk a necessity.
