Asbestos fibre classification and limitation: crushed asbestos fluff stayed within the tariff item, but part of the demand was time-barred.

Asbestos fluff produced by crushing, pulverising and sieving asbestos rock was treated as asbestos fibre under Tariff Item No. 22F because a distinct commercial commodity emerged and the material remained fibrous in character, even though it was not spinnable; that classification was upheld against the assessee. The demand for the period 24-5-1977 to 5-8-1977 was time-barred because limitation had to be tested with reference to the date of the notice, and on that date the claim for that period was beyond six months; that portion of the demand was excluded in favour of the assessee.

Issues: (i) whether the asbestos fluff manufactured from crushed and pulverised asbestos rock was asbestos fibre falling under Tariff Item No. 22F and amounted to manufacture; (ii) whether the demand for the period 24-5-1977 to 5-8-1977 was barred by limitation.

Issue (i): whether the asbestos fluff manufactured from crushed and pulverised asbestos rock was asbestos fibre falling under Tariff Item No. 22F and amounted to manufacture.

Analysis: The process adopted by the respondent involved crushing, pulverising and sieving asbestos rock, from which a distinct commercial commodity emerged. The material was found, on technical evidence and cross-examination of the Chemical Examiner, to consist of short fibres, and the fact that the fibres were not spinnable did not take them outside the relevant tariff item. The reasoning accepted that asbestos remains fibrous in character and that classification depends on fibre length, not on whether the fibre is suitable for spinning.

Conclusion: The fluff was held to be asbestos fibre falling under Tariff Item No. 22F, and this issue was decided against the assessee.

Issue (ii): whether the demand for the period 24-5-1977 to 5-8-1977 was barred by limitation.

Analysis: The period in question exceeded six months from the date of the demand notice. The relevant limitation was to be tested with reference to the date of issue of the notice, and on that date the demand for the said period was beyond time.

Conclusion: The demand for 24-5-1977 to 5-8-1977 was held to be time-barred, and this issue was decided in favour of the assessee.

Final Conclusion: The classification of asbestos fluff under Tariff Item No. 22F was upheld, but the demand was restricted by excluding the time-barred period.

Ratio Decidendi: A commercially distinct product obtained by crushing, pulverising and sieving asbestos rock remains classifiable as asbestos fibre under Tariff Item No. 22F if the material is still fibrous in character, and a demand must satisfy the limitation period as on the date of the notice.
