Manufacturing codes apply when the business transforms inputs into a new product through mechanical, chemical, manual or industrial processes. Pure buying and resale should be checked under wholesale or retail trade.
Choose the Sub-class that best matches the main product line by revenue or production value. If multiple product lines are material, compare 331102 Repair and maintenance of pipes and pipelines, 331103 Repair and maintenance of metal tanks, reservoirs, containers, steel shipping drums and similar items, 331104 Repair and maintenance of steam or other vapor generators and auxiliary plant for use with steam generators such as condensers, economizers, superheaters, steam collectors, and accumulators and document the primary activity before filing.

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 331101 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.
