NIC 331201 - Repair and maintenance of engines and turbines excluding aircraft, ships, vehicle and motor cycle engines

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 331202 Repair and maintenance of pumps and related equipment, fluid power equipment, valves, 331203 Repair and maintenance of metal cutting and metal forming machine tools and accessories, power-driven hand-tools, and other machine tools, 331204 Repair and maintenance of agricultural machinery and forestry and logging machinery including agricultural tractors and document the primary activity before filing.

Check the parent hierarchy, compare 331202 Repair and maintenance of pumps and related equipment, fluid power equipment, valves, 331203 Repair and maintenance of metal cutting and metal forming machine tools and accessories, power-driven hand-tools, and other machine tools, 331204 Repair and maintenance of agricultural machinery and forestry and logging machinery including agricultural tractors, 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.
