EU 2026 Customs Classification: What Importers and Exporters Must Do

Key data

If your company imports or exports goods affected by this regulation and does not update the CN codes in your customs declarations, you may face sanctions, financial surcharges and blockages in customs clearance. Commission Implementing Regulation (EU) 2026/2265, published on 9 October 2026 and in force since 6 October, officially and bindingly sets the classification of certain goods in the Combined Nomenclature (CN), the common tariff system of the entire European Union.

What is relevant for your business is that these classifications are not advisory: they are mandatory in all Member States, and directly affect how much you pay in tariffs, how import VAT is taxed and what trade policy measures apply to your products.

What does this regulation establish?

The Combined Nomenclature (CN) is the tariff coding system used by the EU to classify all goods entering or leaving its territory. Each product receives a numerical code that determines the applicable fiscal and customs regime: import tariffs, VAT, quotas, anti-dumping measures, etc.

Commission Implementing Regulation (EU) 2026/2265 establishes the correct CN codes for certain goods that, until now, may have been classified differently by different operators or Member States. By setting an official classification, the European Commission eliminates ambiguity and requires all economic agents to apply the same code.

The practical consequences of this classification are direct:

• The CN code determines the applicable tariff rate on import.
• It conditions import VAT and other associated tax charges.
• It activates or deactivates the application of trade policy measures (quotas, anti-dumping measures, tariff preferences with third countries).
• It is the basis on which the customs declaration is completed before the authorities.

As an Implementing Regulation, its application is direct in all Member States without the need for national transposition. It enters into force immediately from the date indicated.

Economic and operational impact

A change in the CN code of a product can have significant economic consequences for an importing or exporting company. The impact occurs at three levels:

• Tariff costs: A different CN code may imply a different tariff rate, which directly modifies the import cost of each shipment. If the new code applies a higher tariff, the product margin is reduced immediately.
• Import VAT: Tariff classification can also determine the type of VAT applicable at destination, with an impact on the company's cash flow and tax management.
• Risk of sanctions and delays: Declaring an incorrect CN code—even if due to lack of knowledge of the new classification—can result in financial sanctions, surcharges from customs and delays in clearance that affect the supply chain.

The operational risk is particularly relevant for companies with high frequency of customs operations, as each incorrect declaration accumulates regulatory exposure.

Who does it affect?

• Importers of goods classified in the regulation operating from third countries to the EU.
• Exporters from the EU whose goods are included in the scope of the regulation.
• Logistics operators and customs agents who process customs declarations on behalf of their clients.
• Customs and tax advisors who manage tariff classification of products for companies.
• CFOs and operations directors of companies with international trade, who must validate that their declaration processes are up to date.

Practical example

Imagine a Spanish company that regularly imports an industrial product from China. Until now, that product was declared under a specific CN code that implied, for example, a tariff of 3.5%. Regulation 2026/2265 establishes that the correct classification corresponds to a different CN code, to which a tariff of 6.5% applies.

If the company does not detect this change and continues to declare the previous code, customs may reject the declaration, apply surcharges on the unpaid tariff difference and, depending on applicable national legislation, impose additional sanctions. Furthermore, the clearance of the goods is blocked until the error is corrected, with the consequent impact on delivery times and the relationship with the end customer.

The solution is simple but urgent: review with the logistics operator or customs advisor whether your own products are included in the scope of the regulation and update the CN codes in your management systems before the next operation.

What should companies do now?

1. Identify whether your products are within the scope of the regulation: Review the text of Regulation 2026/2265 or consult with your customs advisor to determine whether any of the goods you import or export are affected by the new classifications.
2. Update CN codes in customs declarations: If any product is included, immediately update the CN code in all customs management documents and systems. The regulation has been in force since 6 October 2026.
3. Review the impact on costs: Calculate whether the new CN code implies a change in the tariff rate or import VAT, and adjust budgets and prices if necessary.
4. Coordinate with the logistics operator: Ensure that the customs agent or logistics operator that processes declarations on your behalf is also aware of the change and applies it correctly.
5. Document the change internally: Record the update of CN codes to have traceability in case of subsequent customs inspection.
