Coking coal classification for import exemption cannot be defeated by later clarificatory amendments applied retrospectively.

An exemption dispute concerning imported coal turned on whether the goods qualified as coking coal under the notification in force at the time of import. The technical material supported classification as coking coal because the coal was suitable for pulverized coal injection and metallurgical use, and the Revenue did not displace the assessee's evidence that it was used in steel manufacture without prior conversion into coke. Later explanatory amendments issued in 2011 were treated as only clarificatory technical criteria and could not be applied retrospectively to deny exemption for earlier imports. The chemical examiner's report was treated as an unsupported opinion, and the description discrepancy did not affect the core classification. The exemption was sustained and the Revenue's challenge failed.

Issues: Whether the imported coal was coking coal eligible for exemption under Notification No. 21/2002-Cus. and whether the later explanatory amendments could be applied to deny the benefit for past imports.

Analysis: The notification in force at the time of import did not define coking coal. The available technical material showed that the goods were suitable for pulverized coal injection and for metallurgical use, and the Revenue did not successfully rebut the assessee's case that the coal was used in steel manufacture without prior conversion into coke. The subsequent explanations introduced in 2011 only supplied technical criteria and did not require actual conversion into coke before use, and those later criteria could not govern earlier imports. The chemical examiner's report was treated as an opinion without disclosed parameters, and the alleged discrepancy in description or the later corrigendum to the appellate order was held not ative of the core classification issue.

Conclusion: The imported goods were held to be coking coal entitled to exemption, and the Revenue's challenge failed.

Final Conclusion: The appeals were rejected and the exemption benefit granted by the first appellate authority was sustained.

Ratio Decidendi: Where an exemption entry uses an undefined technical expression, the classification must be determined on the basis of the notification in force at the time of import, the ordinary and technical meaning of the goods, and the available evidence of use, and later explanatory amendments cannot be applied retrospectively to defeat the exemption.
