Manufacture of gas
What this code covers
Use this class for manufacture of gas when the main activity includes Production of gaseous fuels for energy supply through a gas distribution network (e.g. by carbonation of coal, gasification of lignite, electrolysis or methanisation) and Production of gaseous fuels for energy supply with a specified calorific value, by purification, blending and other processes from gases of various types, including natural gas or hydrogen. Check exclusions and nearby codes before applying it to a mixed activity.
Official NACE Rev. 2.1 labels and explanatory notes are imported from the source dataset. Plain-language explanations are shown separately so readers can compare interpretation with the source text.
No child codes; this is a class-level code.
- production of gaseous fuels for energy supply through a gas distribution network (e.g. by carbonation of coal, gasification of lignite, electrolysis or methanisation)
- production of gaseous fuels for energy supply with a specified calorific value, by purification, blending and other processes from gases of various types, including natural gas or hydrogen
- production of biogas for the purpose of gas supply (e.g. from sewage sludge, manure, waste)
- production of gaseous biofuels for energy supply through a gas distribution network
- extraction of crude natural gas, see 06.20
- production of coke oven gas, see 19.10
- manufacture of refined petroleum products, see 19.20
- production of liquefied petroleum gas (LPG), see 19.20
- Compare with 06.20, 19.10, 19.20 when the main activity overlaps another code.
- Check national equivalent caveats before using this code for local registration or filing workflows.
- If the main revenue activity appears in an exclusion, compare the alternative code before deciding.

What is NACE 35.21 used for?
Use NACE 35.21 for manufacture of gas when the main activity matches this scope: Use this class for manufacture of gas when the main activity includes Production of gaseous fuels for energy supply through a gas distribution network (e.g. by carbonation of coal, gasification of lignite, electrolysis or methanisation) and Production of gaseous fuels for energy supply with a specified calorific value, by purification, blending and other processes from gases of various types, including natural gas or hydrogen. Check exclusions and nearby codes before applying it to a mixed activity.
What are typical examples for 35.21?
Typical examples include Production of gaseous fuels for energy supply through a gas distribution network (e.g. by carbonation of coal, gasification of lignite, electrolysis or methanisation), Production of gaseous fuels for energy supply with a specified calorific value, by purification, blending and other processes from gases of various types, including natural gas or hydrogen, and Production of biogas for the purpose of gas supply (e.g. from sewage sludge, manure, waste).
When might 35.21 not be the right code?
Review another code when the activity is closer to extraction of crude natural gas, see 06.20 and production of coke oven gas, see 19.10.
Which codes should I compare before choosing 35.21?
Compare 35.21 with 06.20 Extraction of natural gas, 19.10 Manufacture of coke oven products, and 19.20 Manufacture of refined petroleum products and fossil fuel products when the activity description is ambiguous.

Rev. 2 code 35.21 maps to the same Rev. 2.1 class 35.21 Manufacture of gas.
Official close match imported from NACE Rev. 2.1.
Low operational impact is expected, but systems should still store the target Rev. 2.1 version explicitly.
Confirm the target version field and update references where Rev. 2.1 is required.
