ISIC 3520 corresponds to NACE 35.21 ≈, NACE 35.22 ≈ and NACE 35.23 ≈ in the European NACE Rev. 2.1 classification. This ISIC class maps to multiple NACE classes because NACE subdivides the activity at a finer level.
About partial correspondence: A “≈” symbol indicates an imperfect mapping. The ISIC and NACE codes do not share identical boundaries — activities covered here may partially overlap with adjacent classes in the other system.
Explanatory Notes
This class includes the manufacture of gas and the distribution of natural or synthetic gas to the consumer through a system of mains. Gas marketers or brokers, which arrange the sale of natural gas over distribution systems operated by others, are included. The separate operation of gas pipelines, typically done over long distances, connecting producers with distributors of gas, or between urban centers, is excluded from this class and classified with other pipeline transport activities.
This class includes:
- production of gas for the purpose of gas supply by carbonation of coal, from by-products of agriculture or from waste
- manufacture of gaseous fuels with a specified calorific value, by purification, blending and other processes from gases of various types including natural gas
- transportation, distribution and supply of gaseous fuels of all kinds through a system of mains
- sale of gas to the user through mains
- activities of gas brokers or agents that arrange the sale of gas over gas distribution systems operated by others
- commodity and transport capacity exchanges for gaseous fuels
