NIC 251301 is the final six-digit endpoint for Manufacture of steam or other vapour generating boilers and hot water boilers other than central heating boilers. It should be selected only when the enterprise's primary manufacturing activity matches this title more closely than 251302 Manufacture of nuclear reactors, except isotope separators, 251303 Manufacture of auxiliary plant for use with steam generators (condensers, economizers, superheaters, steam collectors and accumulators), 251399 Manufacture of other steam generators/boilers (except central heating hot water boilers), n.e.c..
Choose 251301 only when operations, invoices and revenue narrative align with Manufacture of steam or other vapour generating boilers and hot water boilers other than central heating boilers. If the activity also includes 251302 Manufacture of nuclear reactors, except isotope separators, 251303 Manufacture of auxiliary plant for use with steam generators (condensers, economizers, superheaters, steam collectors and accumulators), 251399 Manufacture of other steam generators/boilers (except central heating hot water boilers), n.e.c., 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 251302 Manufacture of nuclear reactors, except isotope separators, 251303 Manufacture of auxiliary plant for use with steam generators (condensers, economizers, superheaters, steam collectors and accumulators), 251399 Manufacture of other steam generators/boilers (except central heating hot water boilers), n.e.c. and document the primary activity before filing.
Check the parent hierarchy, compare 251302 Manufacture of nuclear reactors, except isotope separators, 251303 Manufacture of auxiliary plant for use with steam generators (condensers, economizers, superheaters, steam collectors and accumulators), 251399 Manufacture of other steam generators/boilers (except central heating hot water boilers), n.e.c., 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 251301 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.
