While the appeal was pending before the Hon’ble Division Bench, the jurisdictional authority issued a Show Cause Notice and passed an Order-in-Original dated 15 March 2024, confirming the demand of differential GST along with applicable interest and penalty.
The company filed an appeal under Section 107 of the CGST Act, 2017 on 23.10.2024 before the Commissioner (Appeals-II), which was rejected vide Order-in-Appeal dated 23 June 2025, thereby upholding the demand in full.

Union of India &amp; Ors. (MAT 364 of 2023), arising out of a classification dispute concerning whether polypropylene leno bags fall under HSN 6305 33 00, taxable at the rate of 5% or 3923 2900, taxable at the rate of 18%. The Court held that the bags manufactured by the Company fall under HSN 3923 2900, and are therefore taxable at 18%.
