Inclusive tariff classification of manufactured mineral fibre and duty on removal date under excise law

An inclusive tariff definition deeming man-made fibres to be synthetic fibres can cover a manufactured mineral fibre even if it is not textile-grade or capable of being spun into yarn; on that basis, slagwool was treated as classifiable under the synthetic fibre entry. The note also records that a demand is not vitiated where the assessee received the demand and had an opportunity to object before the duty order was passed, so no breach of natural justice was made out. It further states that duty is governed by the rate in force on the date of removal, so goods manufactured before exemption withdrawal remained dutiable when removed afterwards.

Issues: (i) whether Slagwool was classifiable as synthetic fibre under Tariff Item 18 of the Central Excise Tariff; (ii) whether the demand was vitiated for want of a show cause notice; and (iii) whether the quantity manufactured before the exemption was withdrawn could escape duty.

Issue (i): whether Slagwool was classifiable as synthetic fibre under Tariff Item 18 of the Central Excise Tariff.

Analysis: The tariff entry contained an inclusive definition and deemed man-made fibres to be synthetic fibres. Slagwool was found to be a fibre manufactured by man, not a natural fibre, and the entry did not restrict classification to fibres capable of being spun into yarn or used in the textile industry. Its use only for thermal insulation did not take it outside the tariff description.

Conclusion: Slagwool was correctly classifiable under Tariff Item 18 as a synthetic fibre, against the assessee.

Issue (ii): whether the demand was vitiated for want of a show cause notice.

Analysis: The record showed that the appellants were issued the demand and were heard on their objections before the order confirming duty was passed. Since they had an opportunity to meet the demand before adjudication, the complaint of breach of natural justice was not made out.

Conclusion: There was no violation of natural justice, against the assessee.

Issue (iii): whether the quantity manufactured before the exemption was withdrawn could escape duty.

Analysis: The applicable rate of duty was held to be the rate in force on the date of removal under Rule 9A of the Central Excise Rules, 1944. The earlier date of manufacture did not govern the chargeability of the goods removed after withdrawal of exemption.

Conclusion: The pre-withdrawal quantity was also liable to duty at the rate applicable on removal, against the assessee.

Final Conclusion: The classification adopted by the department was sustained, the procedural objection failed, and the exemption claim for the earlier manufactured quantity was rejected, so the appeal stood dismissed.

Ratio Decidendi: Where a tariff entry uses an inclusive definition deeming man-made fibres to be synthetic fibres, a manufactured mineral fibre may fall within the entry even if it is not textile-grade or capable of being spun into yarn; duty is governed by the rate on the date of removal where Rule 9A applies.
