NIC 239902 is the final six-digit endpoint for Manufacture of mineral insulating materials such as slag wool, rock wool and similar mineral wools; exfoliated vermiculite, expanded clays and similar heat insulating, sound-insulating or sound-absorbing materials. It should be selected only when the enterprise's primary manufacturing activity matches this title more closely than 239901 Manufacture of millstones, sharpening or polishing stones and natural or artificial abrasive products, including abrasive powder or grain on a base of textile material, paper, paper board or other material, 239903 Manufacture of articles of diverse mineral substances such as worked mica and articles of mica, of peat, of graphite (other than electrical articles) and similar substances, 239904 Manufacture of friction material and unmounted articles thereof with a base of mineral substances or of cellulose.
Choose 239902 only when operations, invoices and revenue narrative align with Manufacture of mineral insulating materials such as slag wool, rock wool and similar mineral wools; exfoliated vermiculite, expanded clays and similar heat insulating, sound-insulating or sound-absorbing materials. If the activity also includes 239901 Manufacture of millstones, sharpening or polishing stones and natural or artificial abrasive products, including abrasive powder or grain on a base of textile material, paper, paper board or other material, 239903 Manufacture of articles of diverse mineral substances such as worked mica and articles of mica, of peat, of graphite (other than electrical articles) and similar substances, 239904 Manufacture of friction material and unmounted articles thereof with a base of mineral substances or of cellulose, 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 239901 Manufacture of millstones, sharpening or polishing stones and natural or artificial abrasive products, including abrasive powder or grain on a base of textile material, paper, paper board or other material, 239903 Manufacture of articles of diverse mineral substances such as worked mica and articles of mica, of peat, of graphite (other than electrical articles) and similar substances, 239904 Manufacture of friction material and unmounted articles thereof with a base of mineral substances or of cellulose and document the primary activity before filing.
Check the parent hierarchy, compare 239901 Manufacture of millstones, sharpening or polishing stones and natural or artificial abrasive products, including abrasive powder or grain on a base of textile material, paper, paper board or other material, 239903 Manufacture of articles of diverse mineral substances such as worked mica and articles of mica, of peat, of graphite (other than electrical articles) and similar substances, 239904 Manufacture of friction material and unmounted articles thereof with a base of mineral substances or of cellulose, 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 239902 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.
