Definition of superscripts
Notations

Non E - Industries not included in the energy sector

This category comprises all NAICS codes that do not relate to energy industries.

31-33e - Manufacturing, non E

This category comprises the portion of NAICS sector 31-33 'Manufacturing' that does not relate to energy industries.

325 - Chemical manufacturing

This subsector comprises establishments primarily engaged in manufacturing chemicals and chemical preparations, from organic and inorganic raw materials.

  • Exclusion(s)

    • beneficiating mineral ores(212)
    • field processing of crude petroleum and natural gas (See 211 Oil and gas extraction)
    • processing crude petroleum and coal(324)
    • smelting and refining ores and concentrates (See 331 Primary metal manufacturing)
3251 - Basic chemical manufacturing

This industry group comprises establishments primarily engaged in manufacturing chemicals, using basic processes such as thermal cracking and distillation. Chemicals produced in this industry group are usually separate chemical elements or separate chemically-defined compounds.

32511 - Petrochemical manufacturing

This industry comprises establishments primarily engaged in converting feedstocks derived from petroleum, or from petroleum and natural gas liquids, into petrochemicals. Some important processes used in petrochemical manufacturing include steam cracking and steam reforming. For the purpose of defining this industry, petrochemicals consist of acyclic (aliphatic) hydrocarbons and cyclic aromatic hydrocarbons.

325110 - Petrochemical manufacturing

This Canadian industry comprises establishments primarily engaged in converting feedstocks derived from petroleum, or from petroleum and natural gas liquids, into petrochemicals. Some important processes used in petrochemical manufacturing include steam cracking and steam reforming. For the purpose of defining this industry, petrochemicals consist of acyclic (aliphatic) hydrocarbons and cyclic aromatic hydrocarbons.

  • Illustrative example(s)

    • acyclic hydrocarbons (except acetylene), made from refined petroleum or natural gas liquids
    • aromatic cyclic hydrocarbons, made from refined petroleum or natural gas liquids
    • benzene, made from refined petroleum or natural gas liquids
    • butane, made from refined petroleum or natural gas liquids
    • ethane, made from refined petroleum or natural gas liquids
    • ethylene (ethene), made from refined petroleum or natural gas liquids
    • hexane, made from refined petroleum or natural gas liquids
    • paraffins (alkanes), made from refined petroleum or natural gas liquids
    • pentane, made from refined petroleum or natural gas liquids
    • styrene, made from refined petroleum or natural gas liquids
    • toluene, made from refined petroleum or natural gas liquids
    • xylene, made from refined petroleum or natural gas liquids

    All examples

  • Exclusion(s)

    • converting petrochemicals into other basic chemicals (See 325190 Other basic organic chemical manufacturing)
    • manufacturing acetylene (See 325120 Industrial gas manufacturing)
    • manufacturing plastics resins and synthetic rubber (See 325210 Resin and synthetic rubber manufacturing)
    • refining crude petroleum into petrochemicals (See 324110 Petroleum refineries)
