Manufacture and tariff classification of ophthalmic glass moulds turned on commercial identity and essential character.

Grinding and polishing ophthalmic blanks into glass moulds was treated as manufacture because the processed goods were commercially distinct from the raw blanks in name, character and use, with new characteristics and properties. For excise classification, the goods were identified in trade as glass moulds and as articles of glass; the specific glass heading prevailed over Heading 84.80, which was displaced by the exclusion for articles of glass used for technical purposes. The plastic gasket did not alter the essential character of the goods, so classification fell under Heading 70.15 and not Heading 84.80.

Issues: (i) Whether grinding and polishing of ophthalmic blanks into glass moulds amounts to manufacture; (ii) Whether the goods are classifiable under Heading 84.80 or Heading 70.15 of the Central Excise Tariff.

Issue (i): Whether grinding and polishing of ophthalmic blanks into glass moulds amounts to manufacture.

Analysis: The processed material emerging from grinding and polishing was held to be distinct from the raw ophthalmic blanks in name, character and use. The finished product acquired new characteristics and properties, and the process brought into existence a new commercially distinct product.

Conclusion: The process of grinding and polishing amounted to manufacture.

Issue (ii): Whether the goods are classifiable under Heading 84.80 or Heading 70.15 of the Central Excise Tariff.

Analysis: The goods were identified in trade and internationally as glass moulds and were held to be articles of glass. Heading 84.80 covered moulds for glass and other specified materials, whereas Chapter Note 1(c) to Chapter 84 excluded articles of glass used for technical purposes. Applying the tariff interpretation rules, the specific heading for articles of glass and the essential character of the goods prevailed over the presence of the plastic gasket, which only held the two glass moulds together.

Conclusion: The goods were classifiable under Heading 70.15 and not under Heading 84.80.

Final Conclusion: The assessee's appeals failed, while the Revenue's appeal succeeded, resulting in affirmation of classification under Heading 70.15 and rejection of the competing claim to Heading 84.80.

Ratio Decidendi: For tariff classification, the essential character and specific description of the goods govern, and composite goods are classified according to the component giving them their essential character when a more specific heading is available.
