The goods nomenclature is built as a hierarchically structured tree. After the button Browse nomenclature tree has been pressed, the Tariff Browser displays the Nomenclature tree screen with the section list. From that list, after clicking the section number, it is possible to go to the chapter list (two-digit code), then accordingly to the heading list (four-digit code), the sub-heading list (six-digit code), the combined nomenclature – CN list (eight-digit code), and the TARIC nomenclature list (ten-digit code), which is on the lowest tree level.
