  • Extra duty on goods from some countries

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