NIC 432202 - Installation, repair and maintenance of gas fittings and medical gas distribution systems in hospitals

Use building or civil engineering codes for whole-project construction. Use specialized construction codes when the firm mainly performs electrical, plumbing, HVAC, demolition, roofing, finishing or similar trade work.

Use the code that reflects the contractor's own contracted responsibility. A project developer, civil contractor and specialist installer can fall under different NIC codes even on the same site.

Check the parent hierarchy, compare 432201 Installation, repair and maintenance of plumbing for water, gas, and sanitation equipment (excluding hospitals gas fittings), 432203 Installation, repair and maintenance of ventilation, air-conditioning equipment and heating systems (electric, gas, and oil), furnaces, cooling towers, non-electric solar energy collectors, etc., 432204 Installation, repair and maintenance of all sprinkler systems including lawn and fire systems, 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.
