Welding machine classification: an inbuilt transformer does not make the product a standalone transformer for tariff purposes.

Welding transformers manufactured as welding machines with an inbuilt transformer were classified as welding machines under Tariff Heading 8515.00, not as transformers under Tariff Heading 8404.00. The catalogue and expert certificate showed that the product was a welding machine and not a standalone transformer, and the HSN notes relied on by the Revenue were held applicable only where a transformer is presented separately with associated welding equipment. Because the transformer was built into the machine and not supplied as a separate component, the classification in favour of the assessee was upheld and the Revenue's contrary claim was rejected.

Issues: Whether welding transformers manufactured as welding machines with an inbuilt transformer were classifiable under Tariff Heading 8515.00 or as transformers under Tariff Heading 8404.00.

Analysis: The goods were shown, by the catalogue and expert certificate, to be welding machines and not transformers simpliciter. The reasoning accepted that a welding machine may incorporate a transformer within itself, and that the HSN notes relied upon by the Revenue apply where a transformer is presented separately with associated welding head or appliances. On the facts, the transformer was built into the machine and was not supplied as a separate transformer component.

Conclusion: The classification under Tariff Heading 8515.00 was upheld and the Revenue's claim under Tariff Heading 8404.00 was rejected, in favour of the assessee.

Final Conclusion: The appeal failed because the product was treated as a welding machine with an inbuilt transformer rather than a standalone transformer.

Ratio Decidendi: A welding machine incorporating an inbuilt transformer is classifiable as a welding machine and not as a transformer merely because it contains a transformer within it.
