GST rate amendment: broad reclassification and rate adjustments across schedules altering taxable classifications and applicability nationwide. Amendment implements Council recommendations by inserting, substituting and omitting tariff entries across Schedules I-IV to reclassify specified goods and adjust applicable central tax rates. It adds new serial numbers, revises column entries and creates exclusions to clarify which supplies fall within particular rate brackets (for example, distinguishing ethyl alcohol for blending), thereby establishing the operative classification and rate framework effective the day after publication.
