About this level

Practical summary

Class 2011 sits in the PSIC 2019 hierarchy under C Manufacturing > 20 Manufacture of Chemicals and Chemical Products > 201 Manufacture of basic chemicals. This class usually fans out into more specific subclasses such as Manufacture of Ethanol, Manufacture of Industrial (compressed and Liquefied) Gases, and Manufacture of Inorganic Salts and Compounds. It is the level people use when they already know the activity family but still need the exact five-digit match.

Administrative context

Where this code is used

This class is used when a business can already narrow the activity family and only needs to compare the final subclasses such as Manufacture of Ethanol, Manufacture of Industrial (compressed and Liquefied) Gases, and Manufacture of Inorganic Salts and Compounds. It is the level most often checked before a five-digit decision is finalized.

Selection note

How to choose it

Use this class to choose between its final subclasses such as Manufacture of Ethanol, Manufacture of Industrial (compressed and Liquefied) Gases, and Manufacture of Inorganic Salts and Compounds. If two options look close, compare the exact activity, the outputs and the way the business actually earns revenue.

Official note

Source-backed description

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 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 Manufacture of dyes and pigments from any source in basic form or as concentrate Manufacture of chemical elements Manufacture of inorganic acids except nitric acid Manufacture of alkalis, lyes and other inorganic bases except ammonia Manufacture of other inorganic compounds 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, cassava, corn or similar to produce alcohol and esters; other organic compounds, including wood distillation products (e.g. charcoal) etc. Manufacture of distilled water Manufacture of synthetic aromatic products Roasting of iron pyrites Manufacture of products of a kind used as fluorescent brightening agents or as luminophores Enrichment of uranium and thorium ores and production of fuel elements for nuclear reactors This class excludes: Extraction of methane, ethane, butane or propane, see 0620; Manufacture of fuel gases, such as ethane, butane or propane in a petroleum refinery, see 1920; Manufacture of nitrogenous fertilizers and nitrogen compounds, see 2012; Manufacture of ammonia, see 2012; Manufacture of ammonium chloride, see 2012; Manufacture of nitrites and nitrates of potassium, see 2012; Manufacture of ammonium carbonates, see 2012; Manufacture of plastics in primary forms, see 2013; Manufacture of synthetic rubber in primary forms, see 2013; Manufacture of prepared dyes and pigments, see 2022; Manufacture of crude glycerol, see 2023; Manufacture of natural essential oils, see 2029; Manufacture of aromatic distilled waters, see 2029; Manufacture of salicylic and O- acetylsalicylic acids, see 2100. liquefied) gases compounds chlorine compounds fertilizers and nitrogen compounds, n.e.c. 2012 20120 Manufacture of fertilizers and nitrogen compounds This class includes: Manufacture of fertilizers: straight or complex nitrogenous, phosphatic or potassic fertilizers, urea, crude natural phosphates and crude natural potassium salts Manufacture of associated nitrogen products: nitric and sulfonitric acids, ammonia, ammonium chloride, ammonium carbonate, nitrites and nitrates of potassium Manufacture of potting soil with peat as main constituent Manufacture of potting soil mixtures of natural soil, sand, clays and minerals This class excludes: Mining of guano, see 0891; Manufacture of agro-chemical products, such as pesticides, see 2021; Operation of compost dumps, see 3821.

FAQ

What does PSIC Class 2011 cover?

PSIC Class 2011 is the four-digit layer that sits just above the final subclasses and usually defines the activity family for Manufacture of basic chemicals.

How do I compare Class 2011 with the sibling classes?

Read the neighboring classes and compare the exact wording of the child subclasses. Nearby options include 2013 Manufacture of plastics and synthetic rubber in primary forms and 2012 Manufacture of Fertilizers and Nitrogen Compounds.

Why does Class 2011 matter for a filing decision?

It is usually the last broad checkpoint before the five-digit subclass choice, so it is the right place to catch near-miss classifications.
