Trade measures to be aware of

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.

  • Extra duty on goods from some countries

    Trade-defence measures, such as anti-dumping duty, may apply to goods originating in China; any country except China; Türkiye.

    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.

    Check this code in the official EU TARIC database
  • Lower duty for goods from some countries

    Preferential rates exist for goods originating in San Marino; Economic Partnership Agreements; CARIFORUM except Haiti; Comoros (excluding Mayotte), Madagascar, Mauritius, Seychelles and dependencies and Zimbabwe; Botswana, Eswatini, Lesotho, Mozambique and Namibia; GSP-EBA (Special arrangement for the least-developed countries - Everything But Arms); OCTs (Overseas Countries and Territories); Ivory Coast; 52 more origins. Whether you can use one depends on the origin rules for the goods and on the documentation you can show.

    Check this code in the official EU TARIC database
  • A limited quantity at a lower rate

    A tariff quota is recorded for this code. This does not say whether any of the quota is still available. It covers goods originating in any country except Belarus and Russian Federation.

    This is recorded on a more detailed code below this one, so it may not cover your goods.

  • Restrictions and paperwork

    Import restrictions are recorded for goods originating in Ukraine; China; any country.

    Document or certificate conditions are recorded. Customs may ask for:

    • Movement certificate EUR.1
    • Invoice declaration or origin declaration made out by any exporter on invoice or any other commercial document
    • Goods not originating from or destined to Crimea or Sevastopol (Articles 2 and 2b.1 of Council Regulation (EU) No 692/2014)
    • Goods not originating from or not destined for the non-government controlled areas of Ukraine in the oblasts of Donetsk, Kherson, Luhansk and Zaporizhzhia
    • Authorisation to use a customs procedure with economic impact/end-use within the context of an anti-dumping/countervailing measure (Column 8c, Annex A of Delegated Regulation (EU) 2015/2446)
    • Import authorisation (precursors) issued by the competent authorities of the Member State where the importer is established

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 SKAT or TARIC.
