M/s Shiva Writing Company Pvt. Ltd. appealed against the ruling of the West Bengal Advance Ruling Authority, which classified the tips and balls used in manufacturing ball point pens under HSN 9608 99 90 and taxed them at 18%. The appellant argued that these items should be classified under a different HSN that would attract a lower tax rate of 12%, as they are used exclusively in ball point pens, which are taxed at 12%. The appellant contended that the WBAAR's decision was arbitrary and not in accordance with the law, citing various notifications and legal precedents. However, the Appellate Authority found the original classification and tax rate to be correct and upheld the WBAAR's decision.
