Exemption for coated chalk depends on proof of specified use, while duty demand remains confined to normal limitation without suppression.

Precipitated activated calcium carbonate (coated chalk) was treated as covered by the exemption for minerals used as extenders, suspending agents, fillers or diluents, and no distinction was drawn between coated and uncoated chalk; however, exemption depended on proof of actual use for the specified purposes, so verification by the lower authority was required. In the absence of suppression or misstatement, the extended limitation period under Section 11-A could not be invoked, and any duty demand had to be confined to the normal period preceding the show cause notice.

Issues: (i) whether precipitated activated calcium carbonate (coated chalk) was eligible for exemption under Notification No. 23/55-C.E. dated 29.4.55, and (ii) whether duty could be demanded from 30.7.82 and beyond in view of limitation under Section 11-A of the Central Excises and Salt Act, 1944.

Issue (i): whether precipitated activated calcium carbonate (coated chalk) was eligible for exemption under Notification No. 23/55-C.E. dated 29.4.55

Analysis: The exemption covered minerals employed as extenders, suspending agents, fillers or diluents, and chalk including precipitated chalk was within the notification. The product in question was treated as covered by the notification, and no distinction could be drawn between coated and uncoated chalk for denying eligibility. However, entitlement depended upon proof that the product was used for the specified purposes under the notification.

Conclusion: The product was eligible for exemption, but only if the assessee established use as an extender, suspending agent, filler or diluent; the matter required verification by the lower authority.

Issue (ii): whether duty could be demanded from 30.7.82 and beyond in view of limitation under Section 11-A of the Central Excises and Salt Act, 1944

Analysis: The Collector had found no suppression of facts or misstatement, so the longer period could not be invoked. In that situation, the demand had to be confined to the normal limitation period preceding the show cause notice, and a departmental letter dated 30.7.82 could not by itself justify demand from that date.

Conclusion: The demand was restricted to the normal period of limitation and the extended period was not available to the Revenue.

Final Conclusion: The impugned order, including the demand of duty, penalty and confiscation, was set aside, and the matter was remitted for verification of the user condition for exemption with the demand, if any, confined to the normal limitation period.

Ratio Decidendi: Where a product falls within an exemption notification but the exemption is conditioned on actual use for specified purposes, eligibility must be tested on proof of that use, and in the absence of suppression the extended period of limitation cannot be invoked.
