Deliberately added excipients are not impurities, so paracetamol direct compression grade falls outside Chapter 29 classification.

Paracetamol direct compression grade, where excipients were deliberately added to make the product suitable for tablet manufacture, was not a separate chemically defined organic compound under Chapter 29. Chapter Note 1(a) covers only compounds with impurities arising solely from the manufacturing process, not substances intentionally mixed for a specific use. On that basis, treating the added materials as impurities was unsustainable, and classification under sub-heading 2924.00 was rejected in favour of Heading 3823.00.

Issues: Whether paracetamol direct compression grade, containing paracetamol with deliberately added excipients, was classifiable under sub-heading 2924.00 of the Central Excise Tariff Act, 1985 as a separate chemically defined organic compound, or under the residual Heading 3823.00.

Analysis: Chapter Note 1(a) to Chapter 29 applies only to separate chemically defined organic compounds, whether or not containing impurities. The Harmonized System of Nomenclature explains that impurities are only those substances whose presence results solely and directly from the manufacturing process, and not substances deliberately added to make the product suitable for a specific use. Here, the additional ingredients were intentionally mixed with paracetamol to make the product suitable for tablet manufacture, so they could not be treated as permissible impurities. The reasoning adopted by the lower authorities, treating the added materials as impurities despite their deliberate incorporation, was therefore unsustainable.

Conclusion: Classification under sub-heading 2924.00 was not sustainable, and the product was more appropriately classifiable under Heading 3823.00 in favour of the assessee.
