Substantial expansion under Notification No. 50/2003-CE turns on overall installed capacity growth, not machinery in every section.

For exemption under Notification No. 50/2003-CE, substantial expansion is satisfied where the unit's overall installed capacity increases by not less than 25% through installation of additional plant and machinery. The relevant test is the capacity of the unit as a whole, not proof of a new machine in every section. On the facts, the installed capacity rose from 1175 MT to 1825 MT, and the industrial assessment supported that increase. Once exemption was available, the consequential demand of duty, interest and penalty had no independent basis and could not survive.

Issues: (i) Whether the appellant had undertaken substantial expansion by increasing installed capacity by not less than 25% so as to qualify for exemption under Notification No. 50/2003-CE dated 10.06.2003; (ii) Whether the demand of duty, interest and penalty could survive after denial of the exemption.

Issue (i): Whether the appellant had undertaken substantial expansion by increasing installed capacity by not less than 25% so as to qualify for exemption under Notification No. 50/2003-CE dated 10.06.2003.

Analysis: The governing circular clarified that substantial expansion means an increase in installed capacity by not less than 25% resulting from installation of additional plant and machinery, and that the criterion is the increase in capacity of the unit as a whole, not the installation of a particular machine in every section. The record showed that the appellant's installed capacity increased from 1175 MT to 1825 MT, which was more than 25%, and this factual increase was supported by the industrial assessment and was not effectively rebutted. The absence of a new corrugation machine by itself did not negate the overall expansion where additional machinery had been installed and capacity had increased substantially.

Conclusion: The appellant satisfied the condition of substantial expansion and was entitled to the exemption.

Issue (ii): Whether the demand of duty, interest and penalty could survive after denial of the exemption.

Analysis: Once the exemption was found admissible, the foundation for confirmation of duty, interest and penalty disappeared. The demand had been raised only on the premise that the exemption was not available. As the entitlement to exemption was established, the consequential liabilities could not be sustained.

Conclusion: The demand of duty, interest and penalty was unsustainable.

Final Conclusion: The appeals succeeded and the impugned orders were set aside, with consequential relief flowing from recognition of the exemption.

Ratio Decidendi: For the purpose of Notification No. 50/2003-CE, substantial expansion is determined by the unit's overall increase in installed capacity by not less than 25% through additional plant and machinery, and not by proof of expansion in every individual section or installation of a particular machine.
