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; 38 more origins. Whether you can use one depends on the origin rules for the goods and on the documentation you can show.
