Strict compliance with exemption conditions governs concessional excise duty for electrostatic precipitator parts without proof or proper certificate.

Concessional central excise duty under Notification No. 5/99-C.E. was available only on strict compliance with the prescribed certificate condition and proof that the goods fell within the notified description for pollution control. The claimant failed to produce cogent evidence that the high voltage rectifiers were parts of an electrostatic precipitator system, and the certificate relied on was issued for another unit rather than the goods cleared from the relevant unit. A circular could not expand the notification's scope, and the cited precedents were distinguished on their facts. The exemption was therefore denied.

Issues: Whether the appellant was entitled to concessional central excise duty under Notification No. 5/99-C.E. dated 28-2-99 for high voltage rectifiers claimed to be parts of an electrostatic precipitator system, despite the certificate being issued for another unit and despite the absence of evidence establishing that the goods formed part of the system intended for pollution control.

Analysis: The notification allowed concessional duty for electrostatic precipitator systems and their parts only if the prescribed certificate under Condition No. 55 was issued for each case by the competent authority and the goods were shown to be intended for pollution control purposes. The appellants did not produce cogent evidence before the adjudicating authority to establish that the high voltage rectifiers were parts of an electrostatic precipitator system. The certificate relied upon referred to electrostatic precipitator and its parts and was addressed to another unit, while the claim that goods cleared from the Jhansi unit were covered by that certificate was unsupported. The circular relied upon could not enlarge the scope of the notification, and the precedents cited were held distinguishable on their facts because they did not involve a specific condition requiring proof and certification in the manner demanded by the present notification.

Conclusion: The appellant failed to satisfy the conditions of Notification No. 5/99-C.E. and was not entitled to the concessional exemption.

Ratio Decidendi: An exemption notification must be strictly complied with, and where the benefit depends on a specific certificate and proof that the goods satisfy the notified description, the burden lies on the claimant to establish eligibility by cogent evidence.
