Tariff classification by statutory description and chemical evidence upheld, with misdeclaration sustaining extended limitation and penalty.

Where the tariff specifically defines the product, classification must follow the statutory description, chapter notes and chemical evidence rather than generic trade usage. On that basis, the goods were treated as Natural Gasoline Liquid, not naphtha, because the product's boiling range, composition and extraction from natural gas matched the tariff entry for NGL. Misclassification as naphtha was treated as misdeclaration, supporting invocation of the extended period of limitation and penalty provisions. The Department's demand-based case was therefore restored on the footing that the goods were assessable as NGL.

Issues: (i) Whether the product cleared by the assessee was Natural Gasoline Liquid under tariff item 2710 12 20 or Naphtha under tariff item 2710 12 90 of the Central Excise Tariff Act, 1985; (ii) whether the Department was entitled to invoke the extended period of limitation and impose penalty on account of misdeclaration.

Issue (i): Whether the product cleared by the assessee was Natural Gasoline Liquid under tariff item 2710 12 20 or Naphtha under tariff item 2710 12 90 of the Central Excise Tariff Act, 1985.

Analysis: The product was found to be a low boiling liquid extracted from natural gas, with predominance of pentane and hexane, a distillation range ending below 121 C, and characteristics matching the statutory description of Natural Gasoline Liquid. The Tariff specifically defines NGL in Chapter 27, while Naphtha has no separate specific entry in the post-amendment tariff and must be classified by the heading, chapter notes and supplementary notes. In a classification dispute, the express tariff description and chapter notes control over generic technical or trade descriptions, and the chemical examination report together with the surrounding evidence supported NGL rather than Naphtha.

Conclusion: The product was correctly held to be Natural Gasoline Liquid under tariff item 2710 12 20, and not Naphtha.

Issue (ii): Whether the Department was entitled to invoke the extended period of limitation and impose penalty on account of misdeclaration.

Analysis: Once the product was found to have been cleared as Naphtha despite answering to the statutory description of NGL, the misclassification was held to amount to misdeclaration with intent to evade the higher duty applicable to NGL. On that basis, the Department was held entitled to invoke the extended period and the penalty provisions, and the assessee's limitation plea failed.

Conclusion: The extended period of limitation was available to the Department, and penalty was sustainable.

Final Conclusion: The appellate challenge succeeded, the classification adopted by the adjudicating authority was set aside, and the Department's demand-based case was restored on the footing that the goods were assessable as NGL.

Ratio Decidendi: Where the tariff itself specifically defines the product, classification must be determined by the statutory tariff description, chapter notes and chemical evidence, and a deliberate misclassification to obtain a lower duty attracts the extended limitation and penalty consequences.
