3 (b)Is the classification structure identical to the international standard or, if not, how does it differ? (e.g. have additional levels been added to the international standard or have changes been made within the level of the international structure, such as aggregations or additional breakdowns)In order to fit national conditions or meet the administrative demands, some aggregations and additional breakdowns are made, thus the numbers of categories within each level of PCS are different from that of CPC1.0.
3 (c)Please describe deviations from the international standard (in terms of structure, methodology or application rules). Please use examples, if a general statement is not possible.(1) Structural deviations: as depicted in the previous question; (2) Methodological deviations: The PCS allows overlaps or repetitions of products in parts, while the CPC1.0 is a system of categories that are mutually exclusive.
