Final code reached

Other acrylic polymers in unworked form

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 acrylic polymers in unworked form that are not poly(methyl methacrylate) or one of the specifically listed acrylic polymers and copolymers covered by other codes. The product must therefore be an acrylic polymer in unworked form and not match one of those listed products.

For example

  • An acrylic polymer in unworked form, other than the specifically listed products
See the official tariff text

Official tariff text

Acrylic polymers in primary forms (excl. poly"methyl methacrylate", poly[N-"3-hydroxyimino-1,1-dimethylbutyl"acrylamide], copolymer of 2-diisopropylaminoethyl methacrylate with decyl methacrylate in the form of a solution in N,N-dimethylacetamide, containing by weight >= 55% of copolymer, copolymer of acrylic acid with 2-ethylhexyl acrylate containing by weight >= 10% but <= 11% of 2-ethylhexyl acrylate, copolymer of acrylonitrile with methyl acrylate modified with polybutadiene-acrylonitrile "NBR", polymerization product of acrylic acid with alkyl methacrylate and small quantities of other monomers for use as a thickener in the manufacture of textile printing pastes and copolymer of methyl acrylate with ethylene and a monomer containing a non-terminal carboxy group as a substituent, containing by weight >= 50% of methyl acrylate, whether or not compounded with silica)

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.

  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.

10 import lines

When these goods are imported into the EU, the declaration needs a 10-digit code. Under 3906 90 90 the EU tariff has 10 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.

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.
