This class includes: - manufacture of liquefied or compressed inorganic industrial or medical gases: • elemental gases • liquid or compressed air • refrigerant gases • mixed industrial gases • inert gases such as carbon dioxide • isolating gases This class excludes: - extraction of methane, ethane, butane or propane, see 06.20 - manufacture of fuel gases such as ethane, butane or propane in a petroleum refinery, see 19.20 - manufacture of gaseous fuels from coal, waste etc., see 35.21

This class includes: - manufacture of dyes and pigments from any source in basic form or as concentrate This class excludes: - manufacture of prepared dyes and pigments, see 20.30

This class includes the manufacture of chemicals using basic processes. The output of these processes are usually separate chemical elements or separate chemically defined compounds. This class includes: - manufacture of chemical elements (except industrial gases and basic metals) - manufacture of inorganic acids except nitric acid - manufacture of alkalis, lyes and other inorganic bases except ammonia - manufacture of other inorganic compounds - roasting of iron pyrites - manufacture of distilled water This class excludes: - manufacture of industrial gases, see 20.11 - manufacture of nitrogenous fertilisers and nitrogen compounds, see 20.15 - manufacture of ammonia, see 20.15 - manufacture of ammonium chloride, see 20.15 - manufacture of nitrites and nitrates of potassium, see 20.15 - manufacture of ammonium carbonates, see 20.15 - manufacture of aromatic distilled water, see 20.53 - manufacture of basic metals, see division 24

This class includes the manufacture of chemicals using basic processes, such as thermal cracking and distillation. The output of these processes are usually separate chemical elements or separate chemically defined compounds. This class includes: - manufacture of basic organic chemicals: • acyclic hydrocarbons, saturated and unsaturated • cyclic hydrocarbons, saturated and unsaturated • acyclic and cyclic alcohols • mono- and polycarboxylic acids, including acetic acid • other oxygen-function compounds, including aldehydes, ketones, quinones and dual or poly oxygen-function compounds • synthetic glycerol • nitrogen-function organic compounds, including amines • fermentation of sugarcane, corn or similar to produce alcohol and esters • other organic compounds, including wood distillation products (e.g. charcoal) etc. - manufacture of synthetic aromatic products - distillation of coal tar This class excludes: - manufacture of plastics in primary forms, see 20.16 - manufacture of synthetic rubber in primary forms, see 20.17 - manufacture of crude glycerol, see 20.41 - manufacture of natural essential oils, see 20.53 - manufacture of salicylic and O-acetylsalicylic acids, see 21.10

This class includes: - manufacture of fertilisers: • straight or complex nitrogenous, phosphatic or potassic fertilisers • urea, crude natural phosphates and crude natural potassium salts - manufacture of associated nitrogen products: • nitric and sulphonitric acids, ammonia, ammonium chloride, ammonium carbonate, nitrites and nitrates of potassium This class excludes: - mining of guano, see 08.91 - manufacture of agrochemical products, such as pesticides, see 20.20

This class includes the manufacture of resins, plastics materials and non-vulcanisable thermoplastic elastomers, the mixing and blending of resins on a custom basis, as well as the manufacture of non-customised synthetic resins. This class includes: - manufacture of plastics in primary forms: • polymers, including those of ethylene, propylene, styrene, vinyl chloride, vinyl acetate and acrylics • polyamides • phenolic and epoxide resins and polyurethanes • alkyd and polyester resins and polyethers • silicones • ion-exchangers based on polymers This class excludes: - manufacture of artificial and synthetic fibres, filaments and yarn, see 20.60 - shredding of plastic products, see 38.32

This class includes: - manufacture of synthetic rubber in primary forms: • synthetic rubber • factice - manufacture of mixtures of synthetic rubber and natural rubber or rubber-like gums (e.g. balata)
