14 import lines

When these goods are imported into the EU, the declaration needs a 10-digit code. Under 2921 42 00 the EU tariff has 14 lines, each with its own wording.

You or your customs agent pick the line whose wording fits the goods; the last line, "Other", covers what none of the specific wordings describe.

Data of Sept. 1, 2026

Overview

This is an overview: always confirm the exact import line and origin in EU TARIC.

Extra duty on goods from some countries

First

Trade-defence measures, such as anti-dumping duty, may apply to goods originating in:

China
India
any country except China

The duty depends on the producer or exporter, so two shipments of the same goods can be charged differently.

This is recorded on a more detailed code below this one, so it may not cover your goods. See the import lines under this code

Check this code in the official EU TARIC database

Lower duty for goods from some countries

Possible

Preferential rates exist for goods originating in:

San Marino
Comoros (excluding Mayotte), Madagascar, Mauritius, Seychelles and dependencies and Zimbabwe
Botswana, Eswatini, Lesotho, Mozambique and Namibia
Ivory Coast
Cameroon
Fiji
United Kingdom
Georgia
+46 origins

These rates apply to Economic Partnership Agreements; CARIFORUM except Haiti; GSP-EBA (Special arrangement for the least-developed countries - Everything But Arms); OCTs (Overseas Countries and Territories); GSP+ (incentive arrangement for sustainable development and good governance); GSP - General arrangements except India.

Whether you can use one depends on the origin rules for the goods and on the documentation you can show.

Check this code in the official EU TARIC database

A limited quantity at a lower rate

Check

A tariff quota is recorded for this code. This does not say whether any of the quota is still available. It covers goods originating in:

any country except Belarus and Russian Federation

This is recorded on a more detailed code below this one, so it may not cover your goods. See the import lines under this code

Check this code in the official EU TARIC database

Restrictions and paperwork

Important

Import restrictions are recorded for goods originating in:

Ukraine
Belarus
Russian Federation
