Tariff insertion: Corduroy fabrics added to state GST rate schedule, modifying taxable classification under the State Tax (Rate) notification. An amendment to Notification No.5/2017 inserts serial number 6A, commodity code 5801, for Corduroy fabrics into the Table of State Tax (Rate) entries. The amendment is made under the proviso to sub section (3) of the State GST statute and takes effect retrospectively as specified in the notification, thereby updating the State GST rate schedule to include the corduroy textile heading.
