Mining of chemical and fertiliser minerals
What this code covers
Use this class for mining of chemical and fertiliser minerals when the main activity includes Mining of natural phosphates and natural potassium salts and Mining of native sulphur. 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.
- mining of natural phosphates and natural potassium salts
- mining of native sulphur
- extraction and preparation of pyrites and pyrrhotite, except roasting
- mining of natural barium sulphate and carbonate (barytes and witherite), natural borates, natural magnesium sulphates (kieserite)
- extraction of salt, see 08.93
- roasting of iron pyrites, see 20.13
- manufacture of synthetic fertilisers and nitrogen compounds, see 20.15
- Compare with 08.93, 20.13, 20.15 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 08.91 used for?
Use NACE 08.91 for mining of chemical and fertiliser minerals when the main activity matches this scope: Use this class for mining of chemical and fertiliser minerals when the main activity includes Mining of natural phosphates and natural potassium salts and Mining of native sulphur. Check exclusions and nearby codes before applying it to a mixed activity.
What are typical examples for 08.91?
Typical examples include Mining of natural phosphates and natural potassium salts, Mining of native sulphur, and Extraction and preparation of pyrites and pyrrhotite, except roasting.
When might 08.91 not be the right code?
Review another code when the activity is closer to extraction of salt, see 08.93 and roasting of iron pyrites, see 20.13.
Which codes should I compare before choosing 08.91?
Compare 08.91 with 08.93 Extraction of salt, 20.13 Manufacture of other inorganic basic chemicals, and 20.15 Manufacture of fertilisers and nitrogen compounds when the activity description is ambiguous.
Use this class for extraction of salt when the main activity includes Extraction of salt from underground, including by dissolving and pumping and Salt production by evaporation of sea water or other saline waters. Check exclusions and nearby codes before applying it to a mixed activity.
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.
Use this class for manufacture of fertilisers and nitrogen compounds when the main activity includes Manufacture of fertilisers: and Straight or complex nitrogenous, phosphatic or potassic fertilisers. Check exclusions and nearby codes before applying it to a mixed activity.
Use this class for extraction of peat when the main activity includes Peat digging and Preparation of peat to improve quality or facilitate transport/storage. Check exclusions and nearby codes before applying it to a mixed activity.
Use this class for other mining and quarrying n.e.c. when the main activity includes Mining and quarrying of various minerals and materials: and Abrasive materials, asbestos, siliceous fossil meals, natural graphite, steatite (talc), feldspar, etc.. Check exclusions and nearby codes before applying it to a mixed activity.
Use this group for the broader activity area of mining and quarrying n.e.c., including Mining of chemical and fertiliser minerals, Extraction of peat, and Extraction of salt. Open the child codes when a more specific code is needed.
Rev. 2 code 08.91 maps to the same Rev. 2.1 class 08.91 Mining of chemical and fertiliser minerals.

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.
