Common Questions About NIC 3520

Which businesses fall under NIC 3520?

Start here when the business belongs to manufacture of gas; distribution of gaseous fuels through mains and then compare child entries such as 352001 Production of natural and synthetic gases including coal gas except green hydrogen and compressed bio gas, 352002 Production of Green Hydrogen, 352003 Production of compressed Bio Gas, 352004 Disrtibution and sale of gaseous fuels through mains and 1 more.

Is NIC 3520 a final filing code?

No. This is a hierarchy page. Continue to the six-digit Sub-class before using a code in registration or compliance records.

How do I verify that NIC 3520 is correct before filing?

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.

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 3520?

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

How to move from Class 3520 to the right Sub-class

NIC 3520 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.
