Customs code · HS subheading 3911 90

Final code reached

Other condensation or intermolecularly rearranged polymer products

Chemically modified or not, in unprocessed form, excluding the two specifically named polymers

This is a complete 8-digit customs code. Exports and Intrastat use it as it is. For an import into the EU, pick a 10-digit line below.

This code covers condensation products and intermolecularly rearranged polymerisation products, whether chemically modified or not, when they are in unprocessed form and are not one of the two specifically excluded polymers. It is used when no more specific code in this group names the product.

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.

7 import lines

When these goods are imported into the EU, the declaration needs a 10-digit code. Under 3911 90 19 the EU tariff has 7 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.

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

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.
