Exemption Notification Interpretation: can-drying of man-made fabrics was not hydro-extraction because it involved mechanical and thermal stages.

Can-drying of man-made fabrics was not covered by the notified term "hydro-extraction" because that expression was confined to a purely mechanical process of extracting or squeezing out water. The process used here combined mechanical squeezing through mangles with subsequent steam-roller drying, so it was a composite mechanical and thermal operation rather than the single notified process. Applying strict construction to the exemption notification, the entry could not be extended by implication. The assessee was therefore not entitled to exemption from additional excise duty.

Issues: Whether the process of can-drying of man-made fabrics fell within "hydro-extraction" under Notification No. 297/79-C.E. so as to entitle the assessee to exemption from additional excise duty.

Analysis: The exemption notification granted relief only for the specified finishing processes, and its proviso excluded fabrics subjected in the same factory to processes other than those enumerated. The definition of hydro-extraction in the table was confined to a mechanical process of extracting or squeezing out water. The process adopted by the assessee involved two stages: first, mechanical squeezing through mangles, and then drying by steam rollers. The material on record showed that the mechanical stage removed only part of the moisture, while the remaining moisture was removed by thermal drying. Can-drying was therefore a composite process comprising both mechanical and thermal operations, and could not be equated with a purely mechanical hydro-extraction process. In view of the strict construction applicable to exemption notifications, the process could not be brought within the notified entry.

Conclusion: Can-drying was not hydro-extraction under the notification, and the assessee was not entitled to the exemption.
