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. 3 options Go to this section
Check the possible extra duty first Trade-defence measures are recorded here. Whether one applies depends on where the goods come from and who made them. Go to this section

On an EU import declaration

Pick the 10-digit line that matches the goods.

3 import lines

When these goods are imported into the EU, the declaration needs a 10-digit code. Under 3504 00 90 the EU tariff has 3 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.

The standard duty rate is the same on every line.

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

This is the catch-all under 3504 00: it covers what the sibling codes below do not.

Within this parent group, this is where the peptones, other protein substances and derivatives, and skin powder go when they are not the specifically named milk-protein concentrates with a protein content over 85% by weight on a dry-matter basis.

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

Extra duty on goods from some countries

First

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

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

San Marino
Comoros (excluding Mayotte), Madagascar, Mauritius, Seychelles and dependencies and Zimbabwe
