Common Questions About NIC 091002
Does NIC 091002 apply to extraction or only mining support work?
Use the mining or quarrying Sub-class only when the enterprise performs the extraction activity itself. Exploration, drilling, site preparation or contractor support may belong under mining support service codes instead.
Should mineral trading use NIC 091002?
No. Selling coal, ore, stone, sand or fuel without extracting it is usually a wholesale or retail trade activity. Section B is for extraction and directly related mining operations.
How do I verify that NIC 091002 is correct before filing?
Check the parent hierarchy, compare 091001 Services incidental to offshore oil extraction, 091003 Services incidental to offshore gas extraction, 091004 Services incidental to onshore gas extraction, 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.
What happens if I use the wrong NIC code in Udyam or MCA registration?
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.
Is there a legacy NIC 2008 equivalent for NIC 091002?
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 2026 guidance
Before you select NIC 091002
NIC 091002 should be selected only when the official title matches the main revenue-generating activity. If the business also trades, transports, processes, installs or supports the same product or service, compare nearby NIC pages before filing. This reduces the risk of choosing a code that describes the product being handled rather than the activity your enterprise actually performs.
