Transformer parts classification and limitation: buyer-specific components were treated as transformer parts, with no extended period for disclosed classification.

MS frame parts and transformer tanks manufactured against buyer-specific drawings and purchase orders, and supported by buyer and professional certificates, were treated as components exclusively used in transformer manufacture rather than general articles of iron and steel. On that basis, classification under CTH 85049010 as parts of transformers was upheld and the alternative classification under CTH 73269099 was rejected. The text also states that where periodic returns disclosed the adopted classification and the department was aware of the clearances, no suppression or concealment existed, so the extended limitation period could not be invoked and penalty was not sustainable.

Issues: (i) Whether the disputed MS frame parts and transformer tanks were correctly classifiable under CTH 85049010 as parts of transformers or under CTH 73269099 as articles of iron and steel; (ii) Whether the extended period of limitation could be invoked and penalty sustained.

Issue (i): Whether the disputed MS frame parts and transformer tanks were correctly classifiable under CTH 85049010 as parts of transformers or under CTH 73269099 as articles of iron and steel.

Analysis: The goods were manufactured against specific purchase orders and drawings supplied by the buyers, and the buyer certificates as well as the independent professional certificate supported the position that the items were exclusively used in transformer manufacture. The cited precedent on transformer tanks and frames supported treatment of such items as parts of transformers. On the facts, the goods were not mere general articles of iron and steel but components made for use in transformers.

Conclusion: The classification under CTH 85049010 was correct and the contrary classification under CTH 73269099 was not sustainable.

Issue (ii): Whether the extended period of limitation could be invoked and penalty sustained.

Analysis: The periodic returns disclosed the classification adopted by the appellant, and the department was aware of the clearances from the beginning. In the absence of suppression or concealment, the demand could not be raised by invoking the extended period. Since the classification dispute failed in favour of the Revenue, the penalty and demand based on the disputed classification also could not survive.

Conclusion: The extended period of limitation was not invokable and the penalty was not sustainable.

Final Conclusion: The appellant succeeded on merits and on limitation, and the impugned order was set aside with consequential relief.

Ratio Decidendi: Goods manufactured to specific buyer drawings and exclusively used as transformer components are classifiable as parts of transformers, and where the classification adopted is fully disclosed to the department, the extended period cannot be invoked absent suppression of facts.
