Carbon black notification coverage includes acetylene black when the broader commercial meaning and tariff context support inclusion.

The notification term "carbon black" was construed in its proper commercial and descriptive sense, and acetylene black was held to fall within that expression because it is a form of carbon black produced from incomplete combustion or thermal decomposition of acetylene. The Tribunal also relied on the prior tariff description, which expressly treated acetylene black as included in carbon black, to confirm that no narrow exclusion should be implied. On that basis, acetylene black was covered by Notification No. 283/82 and the assessee was entitled to the notified duty benefit; the matter was remanded for working out the admissible credit accordingly.

Issues: Whether acetylene black falls within the expression "carbon black" in Notification No. 283/82 dated 27-11-1982, so as to entitle the assessee to the notified duty benefit.

Analysis: The expression "carbon black" in the notification had to be understood in its proper meaning and not in a cramped sense. The materials before the Tribunal showed that acetylene black is a form of carbon black, being carbon black produced from incomplete combustion or thermal decomposition of acetylene. The fact that the old tariff item expressly mentioned acetylene black as included within carbon black reinforced this understanding. On that basis, the notification description "carbon black" comprehended acetylene black as well.

Conclusion: The assessee was entitled to the benefit of the notification, and the rejection of the credit claim was ?

Final Conclusion: The impugned orders were set aside and the matter was sent back for working out the credit admissible to the assessee in accordance with the Tribunal's finding that acetylene black is covered by the notification.

Ratio Decidendi: Where the goods answer to the broader commercial and descriptive meaning of the notified entry, a specific exclusion is not to be implied, and a notified term covering a genus includes the identified species of the same product.
