Extended limitation and strict exemption conditions in excise law: disclosure defeated suppression, but Phenol LB failed the drug exemption test.

Extended limitation in central excise requires deliberate suppression or misdeclaration with intent to evade duty; where approved classification lists disclosed the product and the department had earlier accepted the classification and exemptions, the longer period was not available and the demand was time-barred. Exemption under Notification No. 234/82 had to be satisfied strictly on its own terms: the product had to fall within the notification's definition of bulk drug, medicine or drug-intermediate and meet the stated use and pharmacopoeial requirements. Phenol LB, being a disinfectant and sanitation material, did not satisfy that test, so exemption was unavailable.

Issues: (i) Whether the demand of central excise duty on Phenol LB for the relevant period was barred by limitation and whether the extended period could be invoked on the basis of suppression or misdeclaration. (ii) Whether Phenol LB qualified as a drug or bulk drug so as to obtain exemption under Notification No. 234/82 dated 1-11-1982.

Issue (i): Whether the demand of central excise duty on Phenol LB for the relevant period was barred by limitation and whether the extended period could be invoked on the basis of suppression or misdeclaration.

Analysis: The approved classification lists disclosed the product and also showed it as a disinfectant, while the departmental authorities had earlier accepted the classifications and granted exemption benefits. On those facts, there was no deliberate suppression or false declaration. The record did not establish any conscious withholding of material information necessary to justify the longer limitation period.

Conclusion: The demand was barred by limitation and invocation of the extended period was not justified; this issue was decided in favour of the assessee.

Issue (ii): Whether Phenol LB qualified as a drug or bulk drug so as to obtain exemption under Notification No. 234/82 dated 1-11-1982.

Analysis: The exemption under the notification was confined to bulk drugs, medicines and drug-intermediates not elsewhere specified, and the explanation required conformity with pharmacopoeial standards and use for diagnosis, treatment, mitigation or prevention of disease. Phenol LB was found to be a disinfectant and cleaning material used for sanitation purposes, not a product answering that description. Classification as a drug under the Drugs & Cosmetics Act did not by itself satisfy the special definition in the exemption notification.

Conclusion: Phenol LB did not fall within the scope of the notification and exemption was unavailable; this issue was decided against the assessee.

Final Conclusion: The duty demand for the earlier and relevant periods was set aside as time-barred, but the claim for exemption under Notification No. 234/82 failed on merits for the remaining appeal, resulting in a mixed outcome.

Ratio Decidendi: Extended limitation in excise matters requires deliberate suppression or misstatement with intent to evade duty, and an exemption notification must be satisfied strictly according to its own definition and conditions, which are not met merely because a product is described as a drug under another statute.
