Extended excise limitation needs proven suppression; plant growth regulators are not pesticides for exemption under the notification.

Extended limitation under excise law could not be invoked because suppression of facts was not affirmatively established; regular filing of classification lists and RT-12 returns showed the Department had knowledge of the product. The product was also held to be a plant growth regulator, not an insecticide or pesticide, so it did not qualify for exemption under Notification No. 234/82. The residuary classification was upheld, and the duty and penalty confirmation was sustained.

Issues: (i) Whether the demand was barred by limitation and the extended period under the excise law could be invoked on the basis of suppression of facts; (ii) whether the product was correctly classifiable as an insecticide or pesticide so as to qualify for exemption under Notification No. 234/82.

Issue (i): Whether the demand was barred by limitation and the extended period under the excise law could be invoked on the basis of suppression of facts.

Analysis: The appellants had filed classification lists and RT-12 returns regularly, and the product had been known to the Department for years. The record did not establish deliberate non-disclosure or suppression sufficient to justify the extended limitation period under the excise law. For invocation of the longer period, suppression of facts must be clearly established, which was not shown on the facts of the case.

Conclusion: The demand for the earlier period was not sustainable on limitation, and the extended period could not be invoked against the assessee.

Issue (ii): Whether the product was correctly classifiable as an insecticide or pesticide so as to qualify for exemption under Notification No. 234/82.

Analysis: The product was found to be a plant growth regulator and not an insecticide or pesticide. The Tribunal followed earlier decisions holding that products functioning as plant growth regulators do not become pesticides merely because they may have some related agricultural use. Since the exemption notification applied only to insecticides and pesticides, the product did not fall within its scope. The classification under the residuary heading was therefore upheld.

Conclusion: The product was not entitled to classification as an insecticide or pesticide, and the exemption under Notification No. 234/82 was unavailable.

Final Conclusion: The order confirming duty and penalty was sustained, and the appeal failed in full.

Ratio Decidendi: For invoking the extended period under excise limitation provisions, suppression of facts must be affirmatively established; and a plant growth regulator is not, merely by its agricultural use, classifiable as an insecticide or pesticide for exemption purposes.
