I am directed to say that doubts have been raised regarding the classification of uninterruptible power supply system (UPSS) under First Schedule CTA ’75 (the Custom Tariff) in the wake of the decision of the Hon’ble CEGAT in the matter of J.K. Synthetic Ltd. v/s. Collector of Customs, Jaipur [1995 (80) ELT 208 (Tribunal)], holding that UPSS are classifiable under heading 8443.80 ibid
