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.

Choose the 10-digit import line Find the EU wording that matches the goods, and read the whole line before you pick it. 8 options Go to this section
State the country of origin: it decides the rate, sanctions and documents The same code can be charged and treated differently depending on where the goods were made.

On an EU import declaration

Pick the 10-digit line that matches the goods.

8 import lines

When these goods are imported into the EU, the declaration needs a 10-digit code. Under 2920 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.

Match the whole wording A line is its own wording plus the grouping text above it. Read both before you settle on one.
