Mining and quarrying
Mining and quarrying include the extraction of minerals occurring naturally as solids (coal and ores), liquids (petroleum) or gases (natural gas), from mines, seabed, and the extraction of salt from sea water, brine, and other saline waters. Extraction can be achieved by different methods such as underground or surface mining, well operation, seabed mining etc. This section includes supplementary activities aimed at preparing the crude materials for marketing, for example, crushing, grinding, cleaning, drying, sorting, beneficiation and concentration of ores and liquefaction of natural gas. Mining activities are classified into divisions, groups and classes on the basis of the principal mineral produced. Divisions 05, 06 are concerned with mining and quarrying of fossil fuels (coal, lignite, petroleum, gas); divisions 07, 08 concern metal ores, various minerals and quarry products. Some of the technical operations of this section, particularly related to the extraction of hydrocarbons, may also be carried out for third parties by specialised units as an industrial service which is reflected in division 09.

Frequently asked questions
What does Section B cover in NIC-2025?
Section B (Mining and quarrying) is a top-level sector of NIC-2025. It groups 5 divisions and 56 activity codes that share this broad economic area.
Do I register a business using a section letter?
No. Registrations such as Udyam, GST and company incorporation use the numeric NIC code (4, 5 or 6 digits), not the section letter. The section only tells you which part of the classification to explore. Open a division below to reach the specific code for your activity.
How do I find the exact NIC code inside Section B?
Drill down from a division to a group, then a class, then the sub-class that matches your activity. You can also use the search box to jump straight to a code by activity name. If you are unsure, IncorpX provides assistance for selecting the correct code for your registrations.
