NIC 239404 - Manufacture of plasters of calcined gypsum or calcined sulphate

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 239401 Manufacture of clinkers and hydraulic cements, including Portland, aluminous cement, slag cement and superphosphate cements, 239402 Manufacture of asbestos cement, 239403 Manufacture of quicklime, slaked lime and hydraulic lime (excluding chewing lime) and document the primary activity before filing.

Check the parent hierarchy, compare 239401 Manufacture of clinkers and hydraulic cements, including Portland, aluminous cement, slag cement and superphosphate cements, 239402 Manufacture of asbestos cement, 239403 Manufacture of quicklime, slaked lime and hydraulic lime (excluding chewing lime), 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.
