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.

  • 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; 50 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.
