Question
What is a good classification system for products?
Answer
⇤#: Something wrong with the first-level codes (there is a leading zero although should not be). This was corrected, but is there more problems with the data? --Jouni (talk) 23:05, 27 December 2013 (EET)
Rationale
UN CPC version 2 seems to be an optimal choice. It contains a hierarchical system for products, 4408 rows in total. It is organised in five hierarchical levels. It is based on ten categories at the top level, numbered from 0 to 9: [1] [2]
- Agriculture, forestry and fishery products
- Ores and minerals; electricity, gas and water
- Food products, beverages and tobacco; textiles, apparel and leather products
- Other transportable goods, except metal products, machinery and equipment
- Metal products, machinery and equipment
- Constructions and construction services
- Distributive trade services; accommodation, food and beverage serving services; transport services; and electricity, gas and water distribution services
- Financial and related services; real estate services; and rental and leasing services
- Business and production services
- Community, social and personal services
