Classification and exemption for vulcanised rubber sheets turned on broad tariff meaning and ordinary construction of non-curing

Grooved rubber sheets emerging after the dump mill stage were treated as plates, sheets or strips under Item 16A(2) because the manufacturer's own flow chart and sample description showed the product as a sheet, and the broad tariff meaning covered grooved sheets. The goods were also held to be unhardened rubber, as the chemical examiner's report described them as flexible and containing insufficient sulphur to establish hard rubber. A fiscal exemption for vulcanised rubber products, non-curing, for tyres was construed according to its ordinary meaning, so pre-cured tread rubber used in retreading tyres qualified because no further curing was required for the tread itself. The exemption claim therefore succeeded.

Issues: (i) Whether the product was classifiable under Item 16A(2) of the Central Excise Tariff as plates, sheets or strips; (ii) whether the product was unhardened; (iii) whether the product was entitled to exemption under Notification No. 47/76-C.E. dated 9-3-1976 as amended by Notification No. 193/80-C.E. dated 8-12-1980.

Issue (i): Whether the product was classifiable under Item 16A(2) of the Central Excise Tariff as plates, sheets or strips.

Analysis: The product description in the manufacturer's own flow chart showed that after the dump mill stage the material was "sheeted out". The sample was also described as a black coloured sheet having grooves on one side. In the absence of any definition of "sheet" in the tariff, the expression was taken in a broad sense so as to include grooved sheets. The fact that the product had a profile-like shape did not displace the specific evidence that it emerged as a sheet.

Conclusion: The product was correctly held to fall under Item 16A(2) and this issue was decided against the assessee.

Issue (ii): Whether the product was unhardened.

Analysis: The chemical examiner's report stated that the product contained a low percentage of sulphur, which was insufficient to treat it as hard rubber, and that the sample was flexible in nature. The reports relied upon by the assessee were not shown to relate to the same sample drawn under proper excise supervision, and they were treated as less reliable than the detailed laboratory report on the goods in dispute.

Conclusion: The product was treated as unhardened rubber and this issue was decided against the assessee.

Issue (iii): Whether the product was entitled to exemption under Notification No. 47/76-C.E. dated 9-3-1976 as amended by Notification No. 193/80-C.E. dated 8-12-1980.

Analysis: The notification exempted vulcanised rubber products, non-curing, for tyres falling under Item 16A(2). The expression "non-curing" was construed in its ordinary, natural and grammatical sense to mean a product that does not require any further curing, and not as merely "not cured". On that interpretation, the pre-cured tread rubber used for retreading tyres qualified for the exemption because, during use, only the cushion gum cured and not the tread itself.

Conclusion: The product was eligible for exemption under the notification and this issue was decided in favour of the assessee.

Final Conclusion: The classification under Item 16A(2) was upheld, but the exemption claim succeeded, with the result that the lower orders were set aside to that extent and relief followed accordingly.

Ratio Decidendi: A fiscal exemption notification must be construed according to its ordinary, natural and grammatical meaning, and where the language indicates that a vulcanised rubber product need not undergo any further curing, the exemption cannot be denied merely because the product has already been vulcanised.
