Abstract: The objective of this report is to recommend a new commodity classification for the next version of the Swedish national freight model system Samgods. The recommendation is based on i) a comparison of commodity classifications in transport models in other countries, ii) an evaluation of classifications in from the viewpoint of modelling transport demand, iii) how well the classification captures behavioral differences among firms in the freight market and iv) statistical considerations. We recommend the classification to be based on the divisional level of the NST 2007 and to include commodity groups 1-14. We recommend to split up group 1 into one category containing round wood and another containing the rest of the items. We also think it is useful to add a commodity group for air freight by combining fractions from other commodities. In total, our recommendation consists of 16 groups.
