Customs duties: why the rate depends on the code and origin

A customs duty is a charge on imported goods. In the EU, customs duties are set under the Common Customs Tariff and collected when goods are released for free circulation.
There is no single duty rate for a product simply because it is described as a motorcycle, chemical, machine or food product. The tariff treatment starts with its customs classification. Origin then determines which of the available rates applies.
This is why two similar products can produce very different customs costs. A different commodity code can carry a different duty. The same code can also produce a different result when the country of origin changes.
How the duty rate is determined
Every product before imported into the EU has to be assigned a commodity code. That classification connects the goods to the measures attached to the code in the tariff.
For goods from countries without a lower applicable rate, the starting point is normally the third-country duty. This is the standard rate shown in the Common Customs Tariff.
Goods of another origin may qualify for a reduced or zero rate. This can arise under a preferential trade arrangement, the Generalised Scheme of Preferences or another tariff measure that gives specified origins different treatment.
Origin is important because buying or shipping goods from a country does not necessarily make them originating there. The applicable rules of origin determine the country attributed to the goods for customs purposes.
The rate and the amount payable are also different questions. Where the duty is ad valorem, it is calculated as a percentage of the customs value. Some products instead carry a specific duty based on quantity, such as an amount per kilogram or tonne. A tariff can also combine percentage and specific components. Classification, origin and customs value can all affect what is ultimately paid.
The “normal” customs duty may not be the only duty
The Common Customs Tariff gives the basic tariff treatment, but some products are subject to additional trade measures.
Anti-dumping duties can apply to imports found to have been dumped on the EU market. Countervailing duties address subsidised imports. Safeguard measures can introduce additional duties once a tariff quota is exhausted or impose another form of temporary protection. Commercial rebalancing measures can also add duties in response to trade measures adopted by another country.
These measures are usually limited to particular goods and origins. A commodity code with an ordinary customs duty of only a few per cent can consequently carry a much higher total duty for one country if an additional measure applies.
This is also why the standard tariff rate should not be read on its own. EU’s database TARIC brings the different EU measures together against the relevant commodity code and origin. It includes third-country duties and tariff preferences alongside tariff quotas, trade defence measures and other requirements connected to the goods.
Rates can change while the commodity code stays the same
Recent EU-US tariff changes provide a clear example.
Regulation (EU) 2026/1455 changed the customs duties applicable to specified goods originating in the United States. It applies from 1 July 2026 until 31 December 2029. Among other changes, the EU removed customs duties on US industrial goods covered by the Regulation.
The commodity codes themselves did not need to change for the customs cost to change. The new treatment was introduced by changing the rate available to goods of US origin. At the same time, another set of duties shows why the legal position can be less straightforward.
In 2025, the EU adopted commercial rebalancing measures on a wide range of US goods through Implementing Regulation (EU) 2025/1564. Some products were assigned substantial additional duties.
Those measures remain in the legislation, but their application is currently suspended. Commission Implementing Regulation (EU) 2026/1893 extended that suspension from 7 August 2026 without setting a new end date.
A trader looking only at the original rebalancing Regulation could see an additional duty that is not currently being charged. Looking only at an older tariff rate could create the opposite problem and miss a newer reduction. The applicable rate is the one in force when the goods are imported.
Use case: motorcycles from the United States
Consider a motorcycle with a cylinder capacity exceeding 800 cm³, classified under CN code 8711 50 00. An importer asks Smart Taric AI what applies when the motorcycle originates in the United States and is imported into the EU. For this code, the standard third-country customs duty is 6%.
The position for US-origin motorcycles is different. Regulation (EU) 2026/1455 provides a 0% tariff rate from 1 July 2026. There is another rate that could easily confuse. Motorcycles under code 8711 50 00 were included among the US products subject to a 25% EU rebalancing duty under Implementing Regulation (EU) 2025/1564. That additional duty is not currently applied because the rebalancing measures are suspended.

The importer is left with the 0% treatment available under Regulation (EU) 2026/1455, provided the motorcycle qualifies as US-origin and the required evidence supports the claim. The product has not changed, and neither has its commodity code. What changed is the tariff treatment attached to its origin.
