Photographic principle governs tariff classification where a machine uses exposure and chemical conversion in its working.

Classification of the imported machine turned on whether it worked on the photographic principle. The record indicated a plate-making unit, a conversion or drying unit, an incorporated camera, sensitized paper, ultraviolet exposure, and chemical conversion, showing that photography was involved in its operation. In the classification contest between Heading 84.34 and Heading 90.10, the decisive test was the photographic principle rather than end-use alone, and goods falling within Chapter 90 were not displaced by Section XVI exclusion rules. On that basis, the machine was classifiable under Heading 90.10, not Heading 84.34, and the refund claim failed.

Issues: Whether the imported machine "Master Maker 153/168" was classifiable under Heading 90.10 or Heading 84.34 of the Customs Tariff Act, 1975, and whether the assessee was entitled to consequential refund and exemption.

Analysis: The decisive question was whether the machine worked on the photographic principle. The record showed that the machine consisted of a plate-making unit and a conversion or drying unit, incorporated a camera, used sensitized paper, and provided for exposure to ultraviolet radiation and chemical conversion. On that basis, the presence of an exposure unit meant that photography was involved in its working. In a classification contest between Heading 84.34 and Heading 90.10, articles falling under Chapter 90 are excluded from Section XVI by Note 1(e), so Heading 90.10 had to be ruled out only if the article did not belong there. The Tribunal preferred the later Supreme Court guidance that the decisive criterion in this context is whether the photographic principle is involved in the working of the goods, rather than end-use alone.

Conclusion: The machine was correctly classifiable under Heading 90.10 and not under Heading 84.34. The refund claim and the appeal failed.

Ratio Decidendi: Where a machine in the competing field of Heading 84.34 and Heading 90.10 works with an exposure unit using the photographic principle, it falls under Heading 90.10 and end-use considerations do not control the classification.
