Sterilization of disposable syringes and needles is not manufacture; no excise duty arises on mere hygienic processing.

Sterilization of disposable syringes and needles did not amount to manufacture under excise law because manufacture requires a transformation that brings into existence a new commodity with a distinct name, character or use. The Court held that mere cleaning, preservation, or rendering an article fit for more convenient use is insufficient where the original commodity remains essentially the same. Since the syringes and needles were complete articles before sterilization and continued to be the same articles afterward, the process only removed bacteria and improved hygienic usability. Excise duty was therefore not attracted.

Issues: Whether sterilization of disposable syringes and needles amounts to manufacture so as to attract excise duty.

Analysis: Manufacture under excise law requires a transformation that brings into existence a new and different commodity having a distinct name, character or use. A mere change, cleaning, preservation, or rendering the article fit for more convenient use does not amount to manufacture if the original commodity remains essentially the same. The decisive question is whether the process changes the commercial identity of the article. Disposable syringes and needles were complete articles in themselves and remained syringes and needles after sterilization. Sterilization only removed bacteria and improved their hygienic usability; it did not create a new marketable commodity or alter their essential character, name, or end use. The process therefore fell within the category of removal of foreign matter from a finished product, not manufacture.

Conclusion: Sterilization of disposable syringes and needles does not amount to manufacture, and excise duty is not attracted.
