Tax classification of corrugated board boxes: corrugation did not alter essential identity, so cardboard box rate applied.

Corrugated board boxes were treated as falling within the category of cardboard boxes for tax classification, because corrugation was held not to change the basic identity of the product. The Court applied the principle that a manufacturing or utility-enhancing process does not, by itself, create a distinct taxable commodity when the essential character remains the same. On that basis, the Tribunal's classification was upheld, and the boxes were liable to tax at the rate applicable to cardboard boxes rather than being treated as unclassified goods.

Issues: Whether corrugated board boxes fell within the category of cardboard boxes and were taxable at the rate prescribed for cardboard boxes under the relevant notification, or were liable to be treated as unclassified goods.

Analysis: The question turned on whether corrugation altered the essential character of the material. The Court applied the principle that a process improving utility does not necessarily change the basic identity of the product. On that reasoning, corrugated board boxes were not regarded as distinct from cardboard boxes for tax classification purposes.

Conclusion: The classification adopted by the Tribunal was upheld. Corrugated board boxes were held taxable as cardboard boxes at the applicable rate and not as unclassified goods.
