Tariff classification requires proof of reclassification and essential character; complex gear blocks fall under Heading 84.25.

In tariff classification disputes, the revenue must justify any departure from an earlier approved classification by stating the grounds in the notice and producing supporting evidence; a mere assertion is insufficient. The proposed reclassification was therefore not sustained. On the product description of Triple Spur Gear Chain Pully Blocks, the goods were treated as a complex power-transmission mechanism with gears, shafts, chain wheels and bearings, so they were not simple pulleys under Heading 84.83. Applying the product literature and explanatory notes, the goods were classified under Heading 84.25 in favour of the assessee.

Issues: (i) Whether the revenue could reclassify the goods without disclosing the basis for departure from the earlier approved classification list and without discharging the burden of proof. (ii) Whether the goods described as Triple Spur Gear Chain Pully Blocks were classifiable under Heading 84.25 or under Heading 84.83.

Issue (i): Whether the revenue could reclassify the goods without disclosing the basis for departure from the earlier approved classification list and without discharging the burden of proof.

Analysis: The show cause notices did not state the grounds for the proposed reclassification. Although the department is not barred from taking a different view from an earlier approved classification, the taxing authority must prove that the goods are taxable under the entry claimed by it and must support the change with evidence. Mere assertion is insufficient, and the initial burden remains on the revenue to justify the proposed departure.

Conclusion: The proposed reclassification was not properly supported and could not be sustained against the assessee.

Issue (ii): Whether the goods described as Triple Spur Gear Chain Pully Blocks were classifiable under Heading 84.25 or under Heading 84.83.

Analysis: The goods were a complex mechanism containing gear shafts, chain wheels, threaded bush, brake disc and ball bearings. The absence of chains did not convert them into simple pulleys. Heading 84.83 covered simple pulleys or pulleys acting merely as guides and not transmitting power, whereas the presence of gears indicated a mechanism intended for transmission of power. On the product literature and the explanatory notes, the goods did not fall within Heading 84.83.

Conclusion: The correct classification was under Heading 84.25 and not under Heading 84.83, in favour of the assessee.

Final Conclusion: The appeal succeeded because the revenue failed to justify the change in classification and the goods were held to fall under Heading 84.25.

Ratio Decidendi: In tariff classification disputes, the revenue bears the burden of proving the correctness of a proposed reclassification, and goods must be classified according to their essential character and the relevant explanatory notes rather than by a simplistic reliance on the absence of one component.
