Strict construction of exemption notifications denies concessional duty for Ball Clay used in porcelain insulators, not resistor components.

Imported Ball Clay qualified for concessional duty only when used to manufacture the exact goods named in the exemption entry, namely ceramic cores or substrates for resistors. Because the assessee used the material for porcelain insulators and did not manufacture resistors, the condition in the notification was not met. The entry could not be widened by substituting a different end-use, and exemption notifications must be construed strictly on their plain wording. The concessional benefit was therefore unavailable on the facts stated.

Issues: Whether imported Ball Clay was eligible for concessional duty under Sl. No. 158 of Notification No. 25/99-Cus. when it was intended for use in the manufacture of porcelain insulators and not ceramic cores or substrates for resistors.

Analysis: The concessional entry applied only to Ball Clay used for manufacture of ceramic cores or substrates for resistors. The assessee's registration and stated use related to porcelain insulators, and there was no claim that it manufactured resistors or that insulators could be equated with resistors. An exemption notification must be strictly construed on its plain language, and the words in the entry could not be substituted or expanded to cover a different finished product. Since the imported material was not intended for the manufacture of the goods specified in the notification, the condition for concession was not satisfied.

Conclusion: The benefit of concessional duty was not admissible to the assessee, and the Revenue's challenge succeeded.

Final Conclusion: The exemption entry was confined to the specified use in relation to resistors, and it could not be extended to Ball Clay used for porcelain insulators.

Ratio Decidendi: Exemption notifications must be interpreted strictly according to their plain terms, and fiscal concession is available only when the imported goods are used for the exact finished goods specified in the notification.
