Commercial identity test governs excisability; Rule 9(2) recovery is confined to clandestine removal, not ordinary disputes.

Where a tariff entry does not define the goods, excisability depends on commercial identity in trade, and Indian Standards may be relevant but not conclusive evidence. The Court held that rough-rolled zinc could not be finally classified as sheets or strips on the writ record and required fresh adjudication on full evidence, while the earlier finding that zinc calots were not exigible remained undisturbed. It further stated that Rule 9(2) of the Central Excise Rules applies to clandestine removal and was not supported on the materials, though the notice could survive only to the extent permissible under Rule 10 if dutiability was later established. Immediate refund was declined as premature, with refund rights left open according to law.

Issues: (i) whether rough-rolled zinc used for punching zinc calots was exigible to duty as sheets or strips under the Central Excises and Salt Act, 1944; (ii) whether the demand notice issued under Rule 9(2) of the Central Excise Rules, 1944 was without jurisdiction and, if not, whether it could be sustained to the extent permissible under Rule 10; and (iii) whether refund of duty paid on zinc calots could be claimed in the writ jurisdiction under Article 226 of the Constitution.

Issue (i): whether rough-rolled zinc used for punching zinc calots was exigible to duty as sheets or strips under the Central Excises and Salt Act, 1944.

Analysis: Excise duty is attracted by manufacture or production, but the article produced must answer the description in the tariff item. Where the Act or tariff does not define the expression, the relevant test is how the goods are understood in trade and commerce. Indian Standards specifications were treated as relevant evidence of commercial identity, but not conclusive by themselves. On the materials before it, the Court held that the question whether rough-rolled zinc was commercially known as sheets or strips could not be finally determined on the writ record and required fresh adjudication by the appellate authority on full evidence.

Conclusion: the question of dutiability of rough-rolled zinc was left for fresh determination by the appellate authority; the earlier finding that zinc calots were not exigible to duty was upheld.

Issue (ii): whether the demand notice issued under Rule 9(2) of the Central Excise Rules, 1944 was without jurisdiction and, if not, whether it could be sustained to the extent permissible under Rule 10.

Analysis: Rule 9(2) was treated as a penal provision aimed at clandestine removal in evasion of duty, and not as a general machinery for recovery where goods were removed under the departmental procedure without concealment. The materials did not justify a finding of clandestine removal. At the same time, if the goods were ultimately found to be dutiable, the case could still fall within Rule 10 as one of short levy or non-levy, limited to the period permitted by that rule.

Conclusion: the notice was invalid under Rule 9(2), but it was capable of being treated as a notice under Rule 10 to the extent legally permissible if the goods were held dutiable.

Issue (iii): whether refund of duty paid on zinc calots could be claimed in the writ jurisdiction under Article 226 of the Constitution.

Analysis: Refund was not granted as an automatic consequence merely because zinc calots were held not dutiable. Questions of limitation, prior assessment, availability of statutory remedies, possible set-off, and the factual basis of payment all had to be considered. Since the very foundation of the demand against rough-rolled zinc remained unresolved, immediate refund was considered premature, though the assessee was left free to seek refund in accordance with law after the fresh determination.

Conclusion: immediate refund was declined, but the assessee's right to pursue refund in accordance with law after the fresh determination was preserved.

Final Conclusion: the writ petition succeeded only in part: the appellate finding against dutiability of rough-rolled zinc was set aside for fresh decision, the Rule 9(2) notice was kept in abeyance and confined to the extent permitted by law if the goods were held dutiable, and the claim for immediate refund was not finally granted.

Ratio Decidendi: where a tariff entry does not define the goods, excisability depends on whether the article is commercially identifiable as the commodity described in the tariff, and recovery under Rule 9(2) lies only for clandestine removal, not for every case of alleged non-payment of duty.
