2 of 4 factors passing
NIC 321103 is the final six-digit endpoint for Production of precious and semi-precious stones (excluding diamond) in the worked state, including the production and working of industrial quality stones and synthetic or reconstructed precious or semi-precious stones. It should be selected only when the enterprise's primary manufacturing activity matches this title more closely than 321101 Manufacture of jewellery of gold, silver, and other precious or base metals, metal clad with precious metals or precious or semi-precious stones, or combinations thereof, 321102 Production of lab-grown diamonds and working (Cutting, polishing, finishing) of diamonds, 321104 Production of worked/ cultured pearls.
Choose 321103 only when operations, invoices and revenue narrative align with Production of precious and semi-precious stones (excluding diamond) in the worked state, including the production and working of industrial quality stones and synthetic or reconstructed precious or semi-precious stones. If the activity also includes 321101 Manufacture of jewellery of gold, silver, and other precious or base metals, metal clad with precious metals or precious or semi-precious stones, or combinations thereof, 321102 Production of lab-grown diamonds and working (Cutting, polishing, finishing) of diamonds, 321104 Production of worked/ cultured pearls, compare those pages before filing.
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 321101 Manufacture of jewellery of gold, silver, and other precious or base metals, metal clad with precious metals or precious or semi-precious stones, or combinations thereof, 321102 Production of lab-grown diamonds and working (Cutting, polishing, finishing) of diamonds, 321104 Production of worked/ cultured pearls and document the primary activity before filing.
Check the parent hierarchy, compare 321101 Manufacture of jewellery of gold, silver, and other precious or base metals, metal clad with precious metals or precious or semi-precious stones, or combinations thereof, 321102 Production of lab-grown diamonds and working (Cutting, polishing, finishing) of diamonds, 321104 Production of worked/ cultured pearls, 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 321103 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.
