Customs code · HS subheading 2932 99

Final code reached

Other heterocyclic compounds containing only oxygen atoms

Excluding non-fused furan-ring compounds, lactones and the specifically listed substances

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 heterocyclic compounds whose heteroatoms are oxygen only. It excludes compounds with a non-fused furan ring, including hydrogenated forms, as well as lactones, isosafrole, 1-[1,3-benzodioxol-5-yl]propan-2-one, piperonal, safrole, tetrahydrocannabinols, carbofuran and inorganic or organic mercury components.

For example

  • 1,4-dioxane
  • 1,3-dioxolane

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.

24 import lines

When these goods are imported into the EU, the declaration needs a 10-digit code. Under 2932 99 00 the EU tariff has 24 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.
