The Eurostat classification ICST-COM which is harmonised with the UNCTAD International Classification of Ship Types, identifies all the ship types. The classification is applicable both to sea-going and to inland waterway craft. The groupings are based according to the construction of the ship or non-ship marine structure, rather than its particular use at a point in time. Legal basis: Directive 2009/42/EC of the European Parliament and of the Council of 6 May 2009 on statistical returns in respect of carriage of goods and passengers by sea (Recast) (Text with EEA relevance). ICST-COM is maintained by Eurostat and published by the Publications Office of the European Union on the EU Vocabularies website.
