Chapter 29 exclusion and extended limitation failed; classification upheld, but demand survives only for the normal period.

Chapter 29 exclusion for Noscapine B.P. and Papavarine S.R. was rejected because the goods did not satisfy the statutory meaning of opium, a derivative of opium, or a narcotic drug under the governing excise law, so classification under sub-heading 2939.1900 was upheld. On limitation, the longer period could not be invoked because the record did not show wilful misstatement, suppression of facts, or intent to evade duty, and the revenue was already aware of the classification dispute. The demand and penalty survived only for the normal period, with quantification remitted for fresh determination.

Issues: (i) Whether Noscapine B.P. and Papavarine S.R. were excluded from Chapter 29 of the Central Excise Tariff as products containing opium or derivatives of opium and therefore not chargeable to central excise duty; (ii) Whether invocation of the extended period for demand and the consequential penalty for the period beyond one year were sustainable.

Issue (i): Whether Noscapine B.P. and Papavarine S.R. were excluded from Chapter 29 of the Central Excise Tariff as products containing opium or derivatives of opium and therefore not chargeable to central excise duty.

Analysis: Chapter Note 9 to Chapter 29 excludes only products containing alcohol, opium, Indian hemp or other narcotic drugs, and the expressions used in the note are to be understood with reference to the definitions in the Medicinal and Toilet Preparations (Excise Duties) Act, 1955. On that statutory definition, the goods in question were found not to be opium, not mixtures of opium, and not derivatives of opium in the defined sense. They were treated as non-narcotic products falling under Chapter sub-heading 2939.1900 as alkaloids of opium and their derivatives.

Conclusion: The exclusion claim failed and the classification under Chapter sub-heading 2939.1900 was upheld against the assessee.

Issue (ii): Whether invocation of the extended period for demand and the consequential penalty for the period beyond one year were sustainable.

Analysis: The record did not disclose material establishing wilful misstatement, suppression of facts, or an intention to evade duty. The revenue was treated as already aware of the classification dispute, so the longer limitation period could not be sustained. As a result, duty and penalty could survive only for the normal period preceding the notice, leaving the exact quantification to be worked out by the adjudicating authority.

Conclusion: The extended period and the corresponding penalty for the period beyond one year were set aside in favour of the assessee.

Final Conclusion: The demand was sustained only to the extent of the normal limitation period on the classification issue, while the excess demand and related penalty were set aside and the matter was remitted for fresh quantification.

Ratio Decidendi: For Chapter 29 exclusion to apply, the goods must answer the statutory definition of opium, derivative of opium, or narcotic drug under the governing excise law; in the absence of suppression or wilful evasion, the extended limitation period cannot be invoked.
