GIR 2(a): When Parts Become One Product

🔓 Can separately shipped components be classified as one complete product? A new EU judgment explains why separate declarations may not settle the question.

Summary: The EU General Court's judgment in Case T-529/25 highlights an important customs classification issue: components imported through separate consignments and customs declarations may still qualify as one complete article under General Interpretative Rule 2(a). Using the example of electric bicycles, this article explains the basic principle, why the decision matters to importers, and why businesses should examine their classification practices when components arrive separately.

1. Can Separate Shipments Become One Customs Article?

Imagine importing the components of an electric bicycle.

The frame arrives in one shipment. The motor arrives in another. Other components follow several weeks later.

Each shipment has its own invoice, transport documents and customs declaration.

Your customs team classifies the goods as individual parts.

But what if the components are intended to form complete electric bicycles?

Could customs classify them as complete bicycles even though they did not arrive together?

The answer may be yes.

Under General Interpretative Rule 2(a), a reference to an article in a tariff heading can include certain incomplete or unfinished articles and complete articles presented unassembled or disassembled.

The rule matters because the classification of a complete product can differ from the classification of its individual components. That difference may affect the applicable duty rate and exposure to trade defence measures.

2. What Has the EU Court Clarified?

On 7 October 2026, the EU General Court delivered its judgment in Case T-529/25, concerning electric bicycle components imported through separate consignments.

The components were imported through multiple customs declarations over a period of months. The case raised the question of whether the goods could still be treated as electric bicycles presented in an unassembled or disassembled state.

The Court clarified that the fact that goods arrive in separate consignments or are covered by separate customs declarations does not, by itself, prevent classification as one complete article under Rule 2(a).

The decisive issue is whether objective factors demonstrate that the components form a whole and comprise all the essential components of the complete article.

This is an important distinction. Separate shipments do not automatically mean separate classification outcomes.

3. Why Should Importers Care?

Consider businesses that import components for assembly, distribution or manufacturing.

Their shipments may arrive at different times because of production schedules, supplier availability, transport arrangements or warehouse capacity. In such situations, the customs classification question may extend beyond the individual declaration.

Relevant considerations may include:

What the imported components are intended to become.
Whether the components are intended to form one complete article.
Whether the components collectively include the essential parts of that article.
What objective evidence exists when the goods are cleared through customs.

The implications can be significant where classification as a complete article changes the applicable duty treatment. For example, the electric bicycle dispute involved Chinese-origin goods for which the classification of complete bicycles had implications for anti-dumping and countervailing duties.

The practical lesson: customs classification may require looking beyond the contents of an individual shipment.

4. Is Your Business Exposed?

If your business imports components separately, consider these questions:

Are components for the same finished product imported under separate declarations?
Do purchasing and logistics records connect the different shipments?
Are customs classifications based solely on how goods arrive?
Could the complete product be subject to a different duty rate or trade measure?

These questions do not automatically mean that your current classifications are incorrect. They identify situations where a closer review may be warranted. The legal assessment depends on the applicable tariff rules, the characteristics of the goods and the evidence surrounding the transactions.

5. What Comes Next?

The latest judgment reinforces the importance of understanding how GIR 2(a) operates when goods arrive in stages. However, applying the rule to a real supply chain requires more than knowing that separate declarations are possible.

Which facts connect the shipments? What evidence matters? When should customs teams escalate a classification decision? And how should businesses document their reasoning?

These are the questions practitioners need to work through before relying on a classification position.
