Trade parlance governs tariff classification; a demand cannot be sustained on grounds beyond the show cause notice.

Tariff classification of a trailer pump must be determined by commercial understanding and trade parlance, not by dictionary meaning alone. On the facts noted, the record did not show that the frame before fitting the engine, pump and other fittings was understood in trade as a trailer, and no independent trailer emerged as a distinct marketable product before assembly; classification under Tariff Item 34(4) was therefore rejected and Tariff Item 68 accepted. The article also states that classification cannot be sustained on a basis beyond the scope of the show cause notice, where the notice alleged duty on an emerging trailer product but the appellate reasoning proceeded on the final trailer pump as such.

Issues: (i) Whether the goods known as trailer pump were classifiable under Tariff Item 34(4) or Tariff Item 68 of the First Schedule to the Central Excise Tariff; (ii) Whether the appellate authority could sustain classification on a basis beyond the scope of the show cause notice.

Issue (i): Whether the goods known as trailer pump were classifiable under Tariff Item 34(4) or Tariff Item 68 of the First Schedule to the Central Excise Tariff.

Analysis: The classification had to be determined on the basis of commercial understanding and trade parlance, not by relying on dictionary meanings in isolation. The record did not show that the frame, before fitting the engine, pump and other fittings, was understood in trade as a trailer. The department also failed to produce evidence that an independent trailer came into existence as a distinct marketable product before assembly of the trailer pump.

Conclusion: The goods were not classifiable under Tariff Item 34(4); the assessee's classification under Tariff Item 68 was accepted.

Issue (ii): Whether the appellate authority could sustain classification on a basis beyond the scope of the show cause notice.

Analysis: The show cause notice proceeded on the footing that duty was proposed on the trailer as an emerging product, whereas the appellate authority decided the matter on the premise of the final trailer pump as such. The finding therefore travelled beyond the notice and could not be sustained on that basis.

Conclusion: The classification could not be upheld on grounds beyond the show cause notice.

Final Conclusion: The demand was set aside and the assessee succeeded on merits as well as on the scope of notice.

Ratio Decidendi: For tariff classification, commercial understanding in the trade prevails over dictionary meaning, and a demand cannot be sustained on a basis that goes beyond the allegations contained in the show cause notice.
