Before you use the code
The code can be right while what you pay still changes, because of where the goods come from, when they arrive, or extra EU measures.
On an EU import declaration
8 import lines
When these goods are imported into the EU, the declaration needs a 10-digit code. Under 2921 29 00 the EU tariff has 8 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.

A suspension is a lower rate the EU grants for specific products; whether your goods qualify depends on the line's wording and conditions.
Exports from the EU and Intrastat normally use the 8-digit code as it is.

Rates, origin and documents
Besides the ordinary duty, the EU records these kinds of measure against this code. They are listed as signals only: whether one applies to your goods can depend on where they come from, who produced them, the exact product and the documents you present. No amounts are worked out here.
Data of Sept. 1, 2026
Preferential rates exist for goods originating in:
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 databaseImport restrictions are recorded for goods originating in:
The EU records document conditions on this code. What customs may ask for depends on where the goods come from, exactly what the product is and the customs procedure.
Proof of origin 2 conditions
If you claim a lower rate for goods from a country the EU has a trade agreement with, customs asks for proof of origin, for example a EUR.1 certificate or an origin declaration.
Sanctions and restricted regions 6 conditions
Some conditions come from EU sanctions rules. They matter when the goods are linked to a country or region the EU restricts trade with.
Product controls and permits 3 conditions
Depending on the exact product, customs may ask for a licence, a permit or a control certificate before the goods are released.
Statements that the goods are outside a rule's scope 1 condition
Some conditions are statements that a rule does not cover the goods, for example that the product is not on a controlled list.
One last classification check
Use this view if you are still unsure the code describes the product precisely.
