Classification of surgical disinfectants, medicament treatment, and limitation turns on product use and absence of suppression.

Hexiprep, Hexiscrub and Hexiaqua were treated as surgical disinfectants because their chlorhexidine gluconate content was used for skin and hand disinfection before surgery, and they were classified under CET sub-heading 3808.90 rather than as medicaments. Hexidine was treated as a medicament because it was shown to have therapeutic use for gingivitis, aphthous ulceration and other oral infections, and it fell under CET sub-heading 3003.10 rather than Chapter 33. On limitation, the extended period was held inapplicable because the classification lists and labels had been filed and approved, with no suppression of facts shown; the demand for the relevant period was therefore time-barred.

Issues: (i) Whether Hexiprep, Hexiscrub and Hexiaqua were classifiable as disinfectants under Chapter 38 or as medicaments under Chapter 30 of the Central Excise Tariff Act, 1985; (ii) whether Hexidine was classifiable as a preparation for oral or dental hygiene under Chapter 33 or as a medicament under Chapter 30 of the Central Excise Tariff Act, 1985; (iii) whether the duty demand for the period March 1988 to November 1989 was barred by limitation.

Issue (i): Whether Hexiprep, Hexiscrub and Hexiaqua were classifiable as disinfectants under Chapter 38 or as medicaments under Chapter 30 of the Central Excise Tariff Act, 1985.

Analysis: The products were based on chlorhexidine gluconate solution and were used for skin, hand, wound and surgical disinfection. Their labels and use showed that they were microbicidal solutions meant to prevent infection, which placed them in the nature of disinfectants. In the absence of a separate tariff heading for antiseptics, and applying the tariff exclusion for medicaments where the goods are properly classifiable as disinfectants, the products were held to fall within Chapter 38. The claimed Chapter 30 classification was therefore excluded.

Conclusion: Hexiprep, Hexiscrub and Hexiaqua were correctly classified under Chapter 38, specifically sub-heading 3808.90, and not as medicaments under Chapter 30.

Issue (ii): Whether Hexidine was classifiable as a preparation for oral or dental hygiene under Chapter 33 or as a medicament under Chapter 30 of the Central Excise Tariff Act, 1985.

Analysis: Hexidine was shown on the evidence to be prescribed for specific therapeutic conditions affecting the mouth and related areas, and the record did not support treatment of the product as a cosmetic or toilet preparation. It did not satisfy the conditions for exclusion under Chapter 33, and the evidence supported its therapeutic use as a medicinal preparation. On that basis, it was held not to be a Chapter 33 product.

Conclusion: Hexidine was classifiable as a medicament under Chapter 30, specifically sub-heading 3003.10, and not under Chapter 33.

Issue (iii): Whether the duty demand for the period March 1988 to November 1989 was barred by limitation.

Analysis: The classification lists and product labels had been placed before the department, and the department had approved the classifications from time to time. On those facts, there was no wilful misstatement or suppression of material facts with intent to evade duty. The extended period was therefore not available.

Conclusion: The demand for the period March 1988 to November 1989 was barred by limitation.

Final Conclusion: The products were classified in different tariff headings according to their essential use and character, and the revenue demand for the disputed period could not be sustained on limitation.

Ratio Decidendi: For tariff classification, the true nature and predominant use of the product govern, and where the assessee has disclosed the relevant product particulars and the department has approved the classifications on that basis, the extended period cannot be invoked absent wilful suppression or misstatement.
