NIC Class 0520 covers Mining of lignite. This is the main comparison layer for deciding which specific six-digit Sub-class best fits the real activity described in Udyam, MCA or MSME workflows. It currently opens into...
Compare nearby hierarchy entries before choosing a code for a registration or business workflow.
Class 0520 is the final decision layer before six-digit Sub-classes such as 052001 Opencast mining (or surface mining) of lignite (brown coal), 052002 Underground mining of lignite (brown coal) including liquification, 052003 Washing, dehydrating, pulverizing, compressing of lignite (brown coal) to improve quality or facilitate transport or storage, 052099 Other operations relating to mining and agglomeration of lignite (brown coal) n.e.c.. Compare the child pages before using a code in a filing.
Class 0520 is used when the final six-digit code is not obvious and official notes or child Sub-classes need to be compared.
Review every child Sub-class under Class 0520. If the wording is still broad, open the six-digit child pages before using a code in registration.
This class excludes: - hard coal mining, see 0510 - peat digging, see 0892 - support activities for lignite mining, see 0990 - test drilling for coal mining, see 0990 - manufacture of lignite fuel briquettes, ovoids and similar solid hard coal fuels see 1920 - work performed to develop or prepare properties for lignite mining, see 4312
Start here when the business belongs to mining of lignite and then compare child entries such as 052001 Opencast mining (or surface mining) of lignite (brown coal), 052002 Underground mining of lignite (brown coal) including liquification, 052003 Washing, dehydrating, pulverizing, compressing of lignite (brown coal) to improve quality or facilitate transport or storage, 052099 Other operations relating to mining and agglomeration of lignite (brown coal) n.e.c..
No. This is a hierarchy page. Continue to the six-digit Sub-class before using a code in registration or compliance records.
Check the parent hierarchy, compare nearby sibling codes in the same parent category, and confirm that the official title matches the main revenue activity. For regulated or filing-critical decisions, verify the source row in the MoSPI dataset.
A wrong code can cause mismatched business descriptions, follow-up questions or later compliance cleanup. It is better to compare nearby codes before filing than to correct a weak classification later.
Use the legacy converter only as a migration aid. Old NIC 2008 matches can suggest where to look, but NIC 2025 should remain the primary reference for new code selection.
NIC 0520 is an intermediate hierarchy page, not usually the final code used in a filing. Use it to compare child entries, read the nearby-code context and move toward the most precise six-digit Sub-class. If the child list contains several similar activities, open each candidate page and compare the wording against the business's real operating model.
