Tariff classification of alginic acid and sodium alginate turns on the scope of synthetic resin entries, not chemical description alone.

Classification of Alginic Acid and Sodium Alginate under the erstwhile Central Excise Tariff turned on whether they answered the description of artificial or synthetic resins and plastic materials in Tariff Item 15A(1). The Tribunal accepted that a product is not brought within that entry merely because it may be chemically describable as an artificial resin; the decisive question is whether it truly falls within the scope of the tariff description as a high polymer of that kind. On that basis, the products were held to fall outside Tariff Item 15A(1) and to remain classifiable under Tariff Item 68, with the assessee's classification sustained and the departmental challenge rejected.

Issues: Whether Alginic Acid and Sodium Alginate were classifiable under Tariff Item 15A(1) of the erstwhile Central Excise Tariff as artificial or synthetic resins and plastic materials, or under Tariff Item 68.

Analysis: Tariff Item 15A covered artificial or synthetic resins and plastic materials, including certain high polymers, but the Tribunal accepted the lower appellate authority's reasoning that the products in dispute did not answer the description of synthetic resins merely because alginic acid could be described as an artificial resin. The classification turned on the nature of the products as high polymers and on the scope of the tariff entry, and the Tribunal found no basis to treat them as falling within Tariff Item 15A(1).

Conclusion: The classification under Tariff Item 68 was upheld and the Revenue's appeal failed.

Final Conclusion: The impugned classification in favour of the assessee was sustained, and the departmental challenge to it was rejected.

Ratio Decidendi: A product is not classifiable under the synthetic resin entry merely because it may be chemically describable as an artificial resin; classification must depend on whether it truly falls within the scope of the specific tariff description.
