GST rate amendments reclassify goods and adjust schedule entries to change state tax applicability on specified products. Amendments to the Mizoram SGST rate notification revise Schedule I-IV by inserting, substituting and omitting tariff entries and descriptions to reclassify specified goods, adjust unit-value thresholds and add or remove items (including ethyl alcohol for blending, fertilizer-grade phosphoric acid, bamboo flooring, brass kerosene pressure stoves, lithium-ion batteries, refrigerators and washing machines), thereby changing the applicability of state GST rates to those goods; the notification fixes the date on which these changes commence.
