Remand-bound classification, limitation, and aggregate-clearance rules shape excise treatment of transmission belting and exempted goods.

Transmission belting classification had to be reconsidered because the lower authority could not ignore final remand directions that treated rubber predominance as relevant and required sample testing; the matter was sent back for fresh adjudication on the available evidence. A duty demand initiated under a provision then in force was held to continue under the normal six-month limitation, so the limitation objection failed. For small-scale exemption, clearances of exempted excisable goods were required to be counted in the aggregate clearance limit because exemption does not alter the excisable character of the goods, and that computation was upheld.

Issues: (i) Whether the assessees' transmission belting was correctly classifiable under Item 16A(4) of the Central Excise Tariff Schedule and whether the lower authority could disregard the remand directions on the predominance of rubber content; (ii) whether the demand for duty was barred beyond six months under Rule 10 of the Central Excise Rules; (iii) whether clearances of exempted excisable goods were to be included while computing the Rs. 20 lakhs aggregate clearance limit for small-scale exemption.

Issue (i): Whether the assessees' transmission belting was correctly classifiable under Item 16A(4) of the Central Excise Tariff Schedule and whether the lower authority could disregard the remand directions on the predominance of rubber content.

Analysis: The remand order had expressly treated the predominance of rubber content as relevant to classification and had directed testing of a sample. That order had attained finality as no appeal was filed against it. The lower authority was bound to act within the limits of the remand and could not re-open the issue by declaring the predominance test irrelevant. The impugned classification order was therefore vitiated. The matter required de novo adjudication, with testing of an available sample if possible, or otherwise consideration of other reliable evidence to determine the rubber content. The relevance of the predominance test was also supported by the earlier exemption notification covering rubber products with rubber compound content below the prescribed limit.

Conclusion: The classification issue was remanded for fresh determination and the assessees succeeded on this issue.

Issue (ii): Whether the demand for duty was barred beyond six months under Rule 10 of the Central Excise Rules.

Analysis: Proceedings initiated under a provision validly in force when commenced can continue despite later repeal or substitution of that provision. On the facts, the normal limitation of six months applied and the extended period was not attracted.

Conclusion: The demand was not time-barred beyond the normal six-month period, and this issue was decided against the assessees.

Issue (iii): Whether clearances of exempted excisable goods were to be included while computing the Rs. 20 lakhs aggregate clearance limit for small-scale exemption.

Analysis: Excisable goods do not cease to be excisable merely because they are exempted from duty by a notification. The aggregate clearance limit therefore had to take into account the value of clearances of exempted excisable goods as well.

Conclusion: The inclusion of exempted clearances was upheld, and this issue was decided against the assessees.

Final Conclusion: The classification dispute was sent back for fresh adjudication, while the limitation objection failed and the aggregate-clearance computation was upheld.

Ratio Decidendi: An authority acting on remand must comply with the specific directions contained in the final remand order, and exempted excisable goods remain part of the excisable turnover for computing aggregate clearance limits unless the statutory scheme clearly excludes them.
