Tariff classification of liquid chlorinated paraffin: clarificatory circular applied retrospectively, defeating the duty demand.

Chlorinated paraffin in liquid form was treated as classifiable under sub-heading 3824 90 rather than Tariff Item 2712 20 10, because the Board circular clarified the existing tariff position instead of creating a new levy. The circular was therefore held to operate retrospectively. On that basis, the classification adopted by the Revenue could not be sustained and the demand based on the contrary entry failed. The decision also distinguished liquid chlorinated paraffins from solid chlorinated paraffin waxes for tariff purposes, leaving the impugned order set aside.

Issues: Whether chlorinated paraffin manufactured in liquid form was correctly classifiable under Tariff Item No. 2712 20 10, and whether the Board circular clarifying classification of chlorinated paraffins operated retrospectively so as to negate the demand based on the contrary classification.

Analysis: The product found by the adjudicating authority to have been manufactured and cleared by the appellant was chlorinated paraffin in liquid form. The Board's circular clarified that chlorinated paraffins/chloroparaffins in liquid form fall under sub-heading 3824 90 of the Central Excise Tariff Act, while chlorinated paraffin waxes in solid form fall under sub-heading 3404.90 after the Budget, 2010. The circular was treated as an interpretation of the existing law and not as a new levy, and therefore it was held to have retrospective effect. On that basis, the demand founded on classification under Tariff Item No. 2712 20 10 for liquid form goods could not survive.

Conclusion: The goods were not classifiable under Tariff Item No. 2712 20 10, the circular applied retrospectively, and the Revenue's classification and duty demand failed.

Final Conclusion: The impugned order was set aside and the appeal succeeded on the classification dispute.

Ratio Decidendi: A circular that merely clarifies the correct classification of goods operates retrospectively because it explains the existing legal position, and a demand founded on an incorrect tariff classification cannot be sustained once the goods are shown to fall within the clarified entry.
