Asbestos waste classification and limitation fail where tariff characteristics are unproven and activity was already disclosed.

Classification of hard ground powder from broken asbestos cement products under heading 6805.90 failed because the Department did not prove that the material had the tariff characteristics of an asbestos-based product or usable fibre content. The extended limitation period was inapplicable because the grinding activity and existence of hard ground waste had already been disclosed in the classification declaration and departmental awareness of the process was on record, so suppression or wilful mis-statement was not established. Duty could not be fastened on the appellant merely because grinding was done by job workers, as the arrangement was found to be on a principal-to-principal basis.

Issues: (i) Whether hard ground powder obtained by grinding broken asbestos cement products was classifiable under heading 6805.90 and exigible to central excise duty; (ii) Whether the demand was barred by limitation under the extended period provision; (iii) Whether any duty liability could be fastened on the appellant when the grinding was undertaken through job workers.

Issue (i): Whether hard ground powder obtained by grinding broken asbestos cement products was classifiable under heading 6805.90 and exigible to central excise duty.

Analysis: Heading 6805.90 covered mixtures with a basis of asbestos or asbestos with magnesium carbonate. The product in question was only powdered material obtained from broken asbestos cement products that had earlier been destroyed under excise supervision. The Department produced no chemical test report or other evidence to show that the product had usable asbestos fibre content, bonding strength, or any use as packing, filtering, heat-insulating material, or as a basis for fabricating asbestos articles. The burden to justify the proposed classification remained on the Department.

Conclusion: The product was not proved to fall under heading 6805.90, and the duty demand on that basis could not be sustained.

Issue (ii): Whether the demand was barred by limitation under the extended period provision.

Analysis: The grinding activity and the existence of hard ground waste had already been disclosed in the classification declaration filed in 1995, which had been verified and approved. The record also showed earlier departmental awareness regarding grinding of broken asbestos cement products. In these circumstances, suppression or wilful mis-statement with intent to evade duty was not established, and the invocation of the extended period was unjustified.

Conclusion: The demand for the period from November 1992 to June 1994 was time-barred.

Issue (iii): Whether any duty liability could be fastened on the appellant when the grinding was undertaken through job workers.

Analysis: The grinding of the broken pieces into powder was admittedly carried out by job workers. On the facts recorded, the transaction was on a principal-to-principal basis and there was no material to treat the job workers as mere hired labour. The liability, if any, would therefore not lie on the appellant in the manner sought by the Revenue.

Conclusion: Duty liability could not be imposed on the appellant on the ground that the grinding was done by job workers.

Final Conclusion: The impugned order was unsustainable in law, and the appellate relief resulted in setting aside the duty demand, interest, and penalties.

Ratio Decidendi: Where classification is disputed, the Department must adduce evidence to establish that the product answers the tariff description; absent proof of marketable characteristics and in the absence of suppression, the extended limitation cannot be invoked, and liability cannot be fastened on the principal manufacturer merely because the process was undertaken through job workers on a principal-to-principal basis.
