Division 20: Manufacture of chemicals and chemical products
Section C, Manufacturing. 20 subcategories with ISTAT's explanatory notes and the ATECO 2022 codes they come from.
ISTAT publishes ATECO 2022 titles in Italian only.
- 20Manufacture of chemicals and chemical products
This division includes the transformation of organic and inorganic raw materials by a chemical process and the formation of products. It distinguishes the production of basic chemicals that constitute the first industry group from the production of intermediate and end-products produced by further processing of basic chemicals that make up the remaining industry classes.
This division also includes the manufacture of liquid biofuels.
Biomass may be used to carry out the manufacture of chemicals and chemical products classified in this division.
