Trade parlance classification limits "aluminium in all its forms"; specialised printing plates fell outside the tax entry.

Pre-sensitised plates and microlith sheets were held not to fall within the entry for "aluminium in all its forms" under the West Bengal Sales Tax Act, 1994. The Tribunal applied trade parlance and commercial identity, holding that fiscal classification depends on how goods are understood in commerce, not on a purely scientific description of the base material. Because the specialised coating and processing gave these goods a distinct character and use in printing, they were not ordinary aluminium plates. On that basis, import did not require a sales tax permit, and the seizure, notice, and penalty proceedings were unsustainable.

Issues: Whether pre-sensitised plates and microlith sheets are covered by entry 3 of Part A of Schedule IV of the West Bengal Sales Tax Act, 1994 as aluminium in all its forms, and consequently whether their import required a sales tax permit and justified seizure and penalty proceedings.

Analysis: The expression "aluminium in all its forms" was held not to be so wide as to include every article made of aluminium regardless of its commercial identity or end use. In construing fiscal entries, the proper approach is the meaning understood in trade and commerce by persons dealing with the goods, not a merely scientific or literal description. Although aluminium is the base material, the photo-sensitive coating and specialised processing give pre-sensitised plates a distinct character, use, and market identity. They are used exclusively in printing presses and newspapers and are not treated in the trade as ordinary aluminium plates. The same reasoning applied to microlith sheets, which were shown to serve the same specialised purpose.

Conclusion: Pre-sensitised plates and microlith sheets are not aluminium plates within entry 3 of Part A of Schedule IV and do not require a sales tax permit for importation. The seizure and connected notice and penalty proceedings were not sustainable.

Ratio Decidendi: In fiscal classification, goods must be identified by their common or trade parlance character and distinct commercial identity; if processing converts the base material into a commercially separate commodity with a specialised use, it does not remain covered by the entry for the original material.
