Standard goods classification for transport statistics (NST 2007), v1:2007
As NST 2007 considers the economic activity from which the goods originate, each of its items is strongly connected to an item of the European Union product and activity classifications Classification of products by activity (CPA) and Statistical classification of economic activities (NACE), which themselves are consistent with their counterparts at UN level, CPC and ISIC.
