Common Questions About NIC 331301

Does NIC 331301 cover manufacturing or only selling the product?

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.

What if the same factory makes several products near NIC 331301?

Choose the Sub-class that best matches the main product line by revenue or production value. If multiple product lines are material, compare 331302 Repair and maintenance of systems parameters measurment equipments (Equipments used during realisation and operalisation) of Space craft and its Launch Vehicle & Orbital Station, 331303 Repair and maintenance of Satellite Ground station, Gateway & VSAT, RF and Baseband equipments, 331304 Repair and maintenance of irradiation, electromedical and electrotherapeutic equipment such as magnetic resonance imaging (MRI) equipment, medical ultrasound equipment, pacemakers, hearing aids, electrocardiographs (ECG), electromedical endoscopic equipment, irradiation apparatus and document the primary activity before filing.

How do I verify that NIC 331301 is correct before filing?

Check the parent hierarchy, compare 331302 Repair and maintenance of systems parameters measurment equipments (Equipments used during realisation and operalisation) of Space craft and its Launch Vehicle & Orbital Station, 331303 Repair and maintenance of Satellite Ground station, Gateway & VSAT, RF and Baseband equipments, 331304 Repair and maintenance of irradiation, electromedical and electrotherapeutic equipment such as magnetic resonance imaging (MRI) equipment, medical ultrasound equipment, pacemakers, hearing aids, electrocardiographs (ECG), electromedical endoscopic equipment, irradiation apparatus, 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.

What happens if I use the wrong NIC code in Udyam or MCA registration?

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.

Is there a legacy NIC 2008 equivalent for NIC 331301?

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 2026 guidance

Before you select NIC 331301

NIC 331301 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.
