Before you use the code

Check the facts that sit outside 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.

Classify your own product, free Look up the current rates and rules
  1. The product and its form Check that your product really matches this description, including what it is made of and the form it arrives in.
  2. Country of origin Trade agreements, sanctions and extra measures can change the treatment of the very same code.
  3. Current tariff measures Check today's rate, any restrictions or licences, and the quantity customs asks for, with Toldstyrelsen or TARIC.

On an EU import declaration

Pick the 10-digit line that matches the goods.

18 import lines

When these goods are imported into the EU, the declaration needs a 10-digit code. Under 2933 19 90 the EU tariff has 18 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.

Some lines depend on what the goods will be used for and need customs authorisation; matching the wording alone does not give a lower rate.

  1. Match the whole wording A line is its own wording plus the grouping text above it. Read both before you settle on one.
  2. Check the intended use On some lines the lower rate belongs to what the goods will be used for, not to the goods alone.
  3. Confirm the authorisation Where the lower rate carries conditions, customs asks for an authorisation before it can be used.

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

Read the signals first. Open only the ones you want to check.

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

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
  • +45 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).

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

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.

Show the EU's own wording for these conditions
  • Movement certificate EUR.1
  • Invoice declaration or origin declaration made out by any exporter on invoice or any other commercial document

Sanctions and restricted regions 10 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.

Show the EU's own wording for these conditions
  • Goods not originating from or destined to Crimea or Sevastopol (Articles 2 and 2b.1 of Council Regulation (EU) No 692/2014)
  • Goods not originating from or not destined for the non-government controlled areas of Ukraine in the oblasts of Donetsk, Kherson, Luhansk and Zaporizhzhia
  • Goods entered the territory of the customs union of the EU and presented to customs authorities prior to the entry into force or to applicability date of the present sanction, whichever is latest (see Article 8f of Regulation (EU) No 765/2006)
  • Import authorisation by virtue of article 1ra paragraph 10 of Council Regulation (EU) 765/2006
  • The prohibitions defined in article 1ra paragraph 1 of Council Regulation (EU) No 765/2006 do not apply (see exemptions in article 1ra paragraph 4)
  • The prohibitions defined in article 1ra paragraph 1 of Council Regulation (EU) No 765/2006 do not apply (see exemptions in article 1ra paragraph 3)
  • Goods entered the territory of the customs union of the EU and presented to customs authorities prior to the entry into force or to applicability date of the present sanction, whichever is latest (see Article 12e of Regulation (EU) No 833/2014)
  • Import authorisation by virtue of article 3i paragraph 3c of Council Regulation (EU) 833/2014
  • The prohibitions defined in article 3i.1 of Council Regulation (EU) No 833/2014 do not apply (see exemptions in article 3i.3aa)
