Existing protective duties will be replaced by the new measure.
The Commission stressed that the duties are an interim solution and that their investigation of possible price dumping practices by Norwegian salmon companies will continue - and may lead to 'permanent' punitive duties lasting up to five years.
The Commission nevertheless considers the arrangement 'fully justified' and taken on the basis of a completely objective process.
Norway has vowed to take the EU duty to the World Trade Organization and has accused the investigation of omitting profitable Norwegian companies in order to have the figures work out as desired.
Norway's Minister of Fisheries and Coastal Affairs Svein Ludvigsen has called the EU scheme a measure to protect inefficient Scottish and Irish salmon farmers from Norwegian competition.
Prime Minister Kjell Magne Bondevik has threatened to answer any EU duties with retaliatory taxes on certain EU goods if the WTO does not determine that the salmon duty is illegal.
