Customs code · HS subheading 8409 91

Final code reached

Parts made exclusively or mainly for spark-ignition piston engines

Not aircraft parts

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 covers parts made exclusively or mainly for spark-ignition piston engines. It does not cover parts for compression-ignition piston engines or parts for use in aircraft.

For example

  • A replacement part made mainly for a spark-ignition piston engine, not for an aircraft and not for a compression-ignition piston engine

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.

13 import lines

When these goods are imported into the EU, the declaration needs a 10-digit code. Under 8409 91 00 the EU tariff has 13 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.

Some lines depend on what the goods will be used for and need customs authorisation; matching the wording alone does not give a lower rate.

  1. Match the whole wording A line is its own wording plus the grouping text above it. Read both before you settle on one.
  2. Check the intended use On some lines the lower rate belongs to what the goods will be used for, not to the goods alone.
  3. Confirm the authorisation Where the lower rate carries conditions, customs asks for an authorisation before it can be used.

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.
