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

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.
Country of origin Trade agreements, sanctions and extra measures can change the treatment of the very same code.
Current tariff measures Check today's rate, any restrictions or licences, and the quantity customs asks for, with Toldstyrelsen or TARIC.

What to do now for an import

The code is settled. What is left is the import declaration around it.

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.

Restrictions and paperwork

Important

Import restrictions are recorded for goods originating in:

Ukraine

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 2 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
