Classification of smoke meter and gas analyzer as measuring tools, not plant and machinery, secured the lower tax rate.

Smoke meter and gas analyzer were held not to be "plant and machinery" under entry 54B of Schedule C of the West Bengal Value Added Tax Act because they are not used in automobile manufacturing, but only to test pollution conformity before vehicles are sold or put on road. They were, however, treated as "tools" under entry 83(c), with "tools" read as a broad, non-exhaustive expression that includes measuring tools. The requirement of manual operation was rejected as too narrow, since electronic or powered measuring instruments may still qualify as tools. The instruments were therefore taxable at 4% in favour of the assessee.

Issues: Whether smoke meter and gas analyzer are classifiable as plant and machinery under entry 54B of Schedule C of the West Bengal Value Added Tax Act, or alternatively as tools under entry 83(c) of Schedule C, and accordingly taxable at 4%.

Analysis: The expression "plant and machinery" was held inapplicable because the instruments are not used for manufacturing automobiles but are used only for testing pollution conformity before vehicles are sold or put on road. On the alternative plea, the term "tools" was treated as a generic expression of wide import, and the illustrative categories in entry 83, including measuring tools, were read as non-exhaustive. The manual-operation requirement adopted by the Tribunal was rejected as unduly restrictive, since modern measuring instruments may operate electronically or with power and still retain their character as tools. The instruments were found to possess measuring functionality and to fall within the measuring tools category.

Conclusion: Smoke meter and gas analyzer are not plant and machinery under entry 54B, but are tools within entry 83(c) of Schedule C and attract tax at 4% in favour of the assessee.
