Aggregate clearance limits under exemption notifications include exempt and nil-rate goods, while later explanations operate prospectively.

An exemption notification linked the monetary ceiling to the aggregate value of clearances of excisable goods under a composite scheme, so clearances of exempted and nil-rate goods were counted in the ceiling computation, not only dutiable removals. The later clarification inserted by a subsequent notification was treated as prospective only and could not be used to alter the position for earlier clearances unless the notification expressly so provided. The discussion concludes that aggregate-clearance limits must be tested on all covered excisable goods and that later explanatory amendments do not operate retrospectively by default.

Issues: (i) Whether, for the purpose of the monetary ceiling under Notification No. 231/85-C.E., the value of all excisable goods, including exempted goods and goods attracting nil rate of duty, had to be included in the aggregate value of clearances. (ii) Whether the explanation inserted by Notification No. 42/89 could be applied retrospectively to clearances made in the earlier period.

Issue (i): Whether, for the purpose of the monetary ceiling under Notification No. 231/85-C.E., the value of all excisable goods, including exempted goods and goods attracting nil rate of duty, had to be included in the aggregate value of clearances.

Analysis: The notification had to be read as a whole and specifically linked the exemption to the aggregate value of clearances of the said goods under Chapter 40, read with the earlier exemption notification. In that setting, the term clearance was not confined to dutiable removals alone. Excisable goods remained relevant clearances even if duty was not payable during the period, and the monetary ceiling had to be tested by taking all such clearances into account.

Conclusion: The value of all excisable goods, including exempted and nil-rate goods, was required to be included, and this issue was decided against the assessee.

Issue (ii): Whether the explanation inserted by Notification No. 42/89 could be applied retrospectively to clearances made in the earlier period.

Analysis: Notification No. 42/89 was a fresh notification and operated prospectively. The later explanation could not be used to rewrite the position governing clearances made before its commencement. The order under appeal was therefore incorrect in applying the later clarification to the prior period.

Conclusion: The explanation inserted by Notification No. 42/89 did not apply retrospectively, and this issue was decided against the assessee.

Final Conclusion: The departmental appeal succeeded, the order of the lower appellate authority was set aside, and the refund relief granted to the assessee did not survive.

Ratio Decidendi: Where an exemption notification expressly requires computation of aggregate clearances under a composite scheme, all excisable clearances covered by the notification structure must be counted, and a later amendment or explanation cannot be given retrospective effect unless the notification so provides.
