What this code covers

Use this class for manufacture of other inorganic basic chemicals when the main activity includes Manufacture of chemical elements (except industrial gases and basic metals) and Manufacture of inorganic acids, except nitric acid. 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.

Official explanatory notes

Imported source text for this NACE Rev. 2.1 record.

This class includes the manufacture of chemicals using basic processes. The output of these processes is 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
